Jul 26, 2021: Isabel García defended successfully her thesis: "A scalable static analysis framework for reliable program development exploiting incrementality and modularity"

The researcher from the IMDEA Software Institute,, Isabel García successfully presented her thesis last Wednesday, July 21. "A scalable static analysis framework for reliable program development exploiting incrementality and modularity" is the title of the work developed by the researcher, directed by the distinguished professor and former director of the Institute, Manuel Hermenegildo. With this thesis, Isabel completes her doctoral studies in artificial intelligence at the Polytechnic University of Madrid (UPM).

Her object of study comes in response of the trend pattern, automatic source code analysis and verification is of great importance both at the level of software development and software maintenance.

Automatic static analysis tools allow inferring properties about software without executing it and without the need for human interaction. When these tools are based on formal methods, the properties are guaranteed to hold and come with a mathematical proof. The usage of these tools during the coding, testing, and maintenance phases of the software development cycle helps reduce efforts in terms of time and cost, as they contribute to the early detection of bugs, automatic optimizations, or automatic documentation. The increasing importance of the reliability of evolving software is evidenced by the current number of tools and on-line platforms for continuous integration and deployment. In this setting, when changes happen fast, analysis tools are only useful if they are precise and, at the same time, scalable enough to provide results before the next change happens.

In this thesis she studies scalable analyses in the context of abstract interpretation. Since a way to improve scalability is to perform coarser abstractions, she first inspect what effect this may have in effectively proving the absence of bugs. Second, she presents a framework for scalable static analyses which is generic, that is, independent of the data abstraction of the program. Isabel presents several algorithms for incrementally reanalyzing whole programs in a context-sensitive manner, reusing as much as possible previous analysis results. A key novel aspect of the approach is to take advantage of the modular structure of programs, typically as defined by the programmer, while keeping a fine-grained relation between the analysis result and the source program.

Additionally, she presents a mechanism for the programmer to help the analyzer in terms of precision and performance by means of assertions. She shows that these assertions together with incremental analysis are specially useful when analyzing generic code. All these algorithms have been implemented and evaluated for different abstract domains within the CiaoPP framework.

Lastly, she presents an application of the analysis framework to perform on-the-fly assertion checking, providing continuous and almost instantaneous feedback to the programmer as the code is written. Her initial experience with this integrated tool shows quite promising results, with low latency times that provide early, continuous, and precise “on-the-fly” semantic feedback to programmers during the development process. This allows detecting many types of errors including swapped variables, property incompatibilities, illegal calls to library predicates, violated numeric constraints, unintended behavior w.r.t. termination, resource usage, determinism, covering and failure, etc.

Jun 18, 2021: A study develops a new protocol that makes cryptocurrency transactions faster and safer

Researchers from the research unit "Security and Privacy" at TU Wien (Lukas Aumayr and his supervisor Prof. Matteo Maffei) in collaboration with the IMDEA Software Institute (Prof. Pedro Moreno-Sánchez, previously postdoc at TU Wien) and the Purdue University (Prof. Aniket Kate) have jointly developed a protocol that makes more secure and faster transactions in cryptocurrencies like Bitcoin.

Nowadays in cities like Tokyo we can subsist with cryptocurrencies like Bitcoin. Buying a coffee, going shopping, taking the bus, paying a taxi drive or even a meal are all accessible if you only got Bitcoin in your (electronic) wallet. This may seem strange for some European countries, -even though there are many cryptocurrencies in the market like ATM and coinradar (Spanish market)- but we are walking at a steady speed to that model that may or may not co-exist with our bank cards in the future.

The popularity of cryptocurrencies is increasing very fast due to the many advantages compared to, for example, Mastercard or Visa. Transactions are usually anonymous, decentralized and global (i.e., same currency is accepted worldwide).

But there is still work to do in security, privacy and efficiency. Fraud can be possible, users can discover information about other users that should be kept secret, the number of transactions is limited, and sometimes delays occur.

The researchers from the IMDEA Software Institute, TU Wien, and Purdue University, aware of these problems, have developed an improved protocol. The article, in which these ideas are based on, will be presented at the [USENIX Security Symposium 2021], one of the best IT security conferences worldwide.

The bottleneck of Bitcoin

"It has long been known that Bitcoin and other blockchain technologies have a scalability problem: There can only be a maximum of ten transactions per second," says Lukas Aumayr of the Security and Privacy research unit at TU Wien. "That's very few compared to credit card companies, for example, which perform tens of thousands of transactions per second worldwide."

An approach to solve this problem is the "Lightning Network" - an additional network of payment channels between blockchain users. For example, if two people want to process many transactions in a short period of time, they can exchange payments directly between each other in this way, without each individual transaction being published on the blockchain. Only at the beginning and at the end of this series of transactions is there an official entry in the blockchain.

As demonstrated by other works of Pedro (IMDEA Software Institute), the apparent privacy gain of the Lightning Network due to off-chain payments isn’t real. In fact, previous work of Pedro has demonstrated that payment intermediaries can learn who pays what to whom. This is an issue that needs to be solved for a system like Lightning Network to become widely used.

A second big issue is that “in addition, everyone in this chain has to contribute a certain amount of money, which is locked as collateral. Sometimes a transaction fails, and then a lot of money can remain locked for a relatively long time – the more people involved, the longer time it will take” says Pedro Moreno-Sánchez.

Mathematically ruling out vulnerabilities

“This project has advanced the state of off-chain payments both theoretically and practically. From the theory point of view, we have provided a formal model of the new payment system, proving mathematically its correctness and security against an adversary. Moreover, while current Lightning Network requires two rounds of communication across all participants in a payment, Blitz (the new protocol) reduces it to a single round of communication. This is a milestone result since Lightning Network and other approaches proposed so far where all using two rounds and it was unknown whether we could beat this barrier” in the IMDEA Software researcher’s words.

“In practice, a single round of communication implies great benefits in practicality” As Lukas said: In the first round, the money is locked, in the second round it is released - or refunded if there were problems. That could mean an extra day of delay for each user in that chain. With our protocol, the communication chain only has to be run through once”

Simulation proves practicality

However, it is not only the fundamental logical structure of the new protocol that is important, but also its practicality. Therefore, the team simulated in a payment channel network how the new technology behaves compared to the previous Lightning network. The advantages of the new protocol became particularly apparent: depending on the situation, such as the number of attacks and fraud attempts, the new protocol results in a factor of 4 to 33 fewer failed transactions than with the conventional Lightning network.

Pedro and Lukas are putting efforts on disseminating the results with the Lightning Network developers as well as other Bitcoin organizations. One of the most attractive points so far is that Blitz is totally backwards compatible with currently deployed technologies and could be immediately deployed as a more secure and faster alternative for off-chain payments.

Jun 7, 2021: The IMDEA Software Institute was present at the IEEE International Conference on Robotics and Automation

The researchers of the IMDEA Software Institute, César Sánchez and Felipe Gorostiaga together with Gerardo Schneider (University of Gothenburg), Sebastian Zudaire and Sebastian Uchitel (both from Universidad de Buenos Aires) have presented the paper: "Assumption Monitoring Using Runtime Verification for UAV Temporal Task Plan Executions" at IEEE International Conference on Robotics and Automation (ICRA 2021).

Temporal task planning guarantees a robot will succeed in its task as long as certain explicit and implicit assumptions about the robot’s operating environment, sensors, and capabilities hold. A robot executing a plan can silently fail to fulfill the task if the assumptions are violated at runtime. Monitoring assumption violations at runtime can flag silent failures and also provide mitigation and remediation opportunities. However, this requires means for describing assumptions combining temporal and quantitative data, automatic construction of correct monitors and ensuring a correct interplay between the planning execution and monitors.

"In this paper we propose combining temporal planning with stream runtime verification, which offers a high-level language to describe monitors together with guarantees on execution time and memory usage. We demonstrate our approach both in real and simulated flights for some typical mission scenarios."

May 26, 2021: Hardware-Software Contracts for Secure Speculation wins the Best Paper Award at the 42nd IEEE Symposium on Security and Privacy

IMDEA Software Institute researchers Marco Guarnieri and Pepe Vila together with Boris Köpf (Microsoft Research) and Jan Reineke (Saarland University) won a best paper award at the 42nd IEEE Symposium on Security and Privacy (S&P) for their paper “Hardware-Software Contracts for Secure Speculation”.

The paper develops a framework for defining hardware-software contracts that capture hardware side-channel security guarantees in a simple, mechanism-independent manner. The framework provides foundations for principled co-design of hardware and software for side-channel resistant systems. Using this framework, the authors characterize the security guarantees provided by recent hardware mechanisms for secure speculation; mapping each mechanism to a set of hardware-software contracts. Contracts are also the basis for secure programming, where different contracts impose distinct software-level requirements for end-to-end security.

Apr 22, 2021: Achieving privacy and integrity in the cloud

Data has emerged as the oil of the 21st century. The importance of data is no longer surprising, but its growing relevance is beginning to take on worrying overtones. Our lives are increasingly dependent on technology that seems to need our data. But where is our data? Where is it stored? Due to the ubiquity of the Internet, everything is now migrated to the cloud.

Zara, Spotify, Netflix, Twitter, practically all companies today use data on which they compute to give us a better service. For example, a music recommendation service should store what we have listened to and cross-reference that data with the data of other people with whom there is a match to try to deduce what else we might like. A financial service could do something similar with investment funds, which is arguably more sensitive information. The same could happen with health data, held by the public health provider or a private company. And all of them, moreover, often have personal information: addresses, email accounts, bank account numbers...

Almost all of these companies rely on external providers for their computing needs: storing data (i.e., delegating its storage) and using it to extract results by running programs on these providers' computers (delegating a computation).

How can we ensure that data and computations that are delegated to third parties are protected against espionage and run correctly? Data can be encrypted, but in order for it to be used by existing software, it needs to be decrypted. At that point, a malicious provider (or a provider that gets hacked) can inspect it and learn data that the company that stored it does not want to disclose and that the person to whom it refers probably does not want to disclose either. Similarly, it could change the program that executes the calculations and return incorrect results, which raises the question of how to check that such results are correct without redoing the computation?

Cryptographic techniques exist to solve both problems. Advancing on them and making them usable in practice is the main objective of the PICOCRYPT project (Cryptography for Privacy and Integrity of Computation on Untrusted Machines), proposed by Dr. Dario Fiore, a researcher at the IMDEA Software Institute of the Madrid Regional Government, which has recently been awarded a Consolidator ERC grant from the European Union (Horizon 2020 research and innovation programme*) to receive funding worth 2 million euros over five years. The European Research Council is the European Union's most prestigious scientific and funding programme. With PICOCRYPT, the IMDEA Software Institute has been granted three projects by this programme (together with RACCOON and MATHADOR).

For Dr. Dario Fiore, cryptography is already a key component to keep our data secure during communication, but "the challenge of PICOCRYPT is to invent new cryptographic protocols to keep our data secure also during computation. The benefits of this paradigm are innumerable. For example, there are people and companies who refrain from using external IT resources because of the risks of this model. With the solutions we intend to design in PICOCRYPT, they could instead use these services securely and without having to fully rely on the providers of these services". It will therefore guarantee the integrity and privacy of computation made with data stored in the cloud and also make it efficient to ensure that delegation is cost-effective.

The IMDEA Software Institute is one of the seven IMDEA Institutes promoted by the Regional Government of Madrid with the aim of carrying out research and scientific development at the highest level.

Mar 20, 2021: Maximiliano Klemen defends sucesfully his thesis: "A General Framework for Static Resource Analysis and Profiling of (Parallel) Programs and an Application to Runtime Checking"

PhD Defense

The IMDEA Software Institute researcher Maximiliano Klemen has successfully defended his PhD thesis on: "A General Framework for Static Resource Analysis and Profiling of (Parallel) Programs and an Application to Runtime Checking", supervised by Prof. Pedro López, on March 5th.

The goal of static cost analysis is to automatically estimate the resources used by program executions without running the programs with concrete data, as functions of input data sizes and possibly other (environmental) parameters. In this thesis he improves and extends state-of-the-art static cost analysis techniques by developing a novel, general and flexible framework for resource usage analysis that can be easily instantiated to infer a wide range of resources, notions of costs, and approximations, which can deal with different programming languages, platforms and execution models.

For some applications, standard resource analyses, which estimate the total resource usage of a program, do not provide the information required. For example, helping developers make resource-related design decisions requires knowing how such total resource usage is distributed over selected parts of a program. The novel, general, and flexible framework developed in Maximiliano's thesis solves this problem, by allowing setting up cost relations that can be instantiated for performing a wide range of resource usage analyses, including both static profiling and the standard notion of cost. He shows how to instantiate such framework to perform static profiling of accumulated cost (also parameterized by input data sizes). Such information identifies the parts of the program that have the greatest impact on the total program cost.

Moreover, parallel computing has become the dominant paradigm in computer architecture, and predicting resource usage on such platforms poses a difficult challenge. We address it by extending and instantiating our general framework for performing resource usage analysis of parallel (logic) programs. Besides cost functions, the analysis also infers other useful information to better exploit and assess the potential and actual parallelism of a system. He also develops a novel application of his cost analysis framework: inferring static performance guarantees for programs with run-time checks. Instrumenting programs for performing run-time checking of properties, such as regular shapes, is a common and useful technique that helps programmers detect incorrect program behaviors. However, such run-time checks inevitably introduce run-time overhead (in execution time, memory, energy, etc.). He proposes a method that uses static analysis to estimate such overhead. This approach can provide guarantees for all possible execution traces, and allows assessing how the overhead grows as the size of the input, which is a parameter of the estimated cost functions, grows. His method also extends an existing assertion verification framework to express “admissible” overheads, and statically and automatically checks whetherthe instrumented program conforms with such specifications.

The accuracy and applicability of his framework strongly depend on the capabilities of the component in charge of solving (or safely approximating) the cost and size recurrence relations generated during the analysis. In this thesis he proposes techniques for solving recurrence relations that extend state-of-the-art solvers, addressing some of their limitations. In particular, he develops a novel approach for solving arbitrary, constrained recurrence relations. It is a guess and check approach that uses well-known machine learning techniques for the guess stage, and a combination of an SMT-solver and a Computer Algebra System for the check stage. Additionally, he develops a method for solving cost relations involving a maximization operator, which appears when representing complex size and cost relations.

Finally, he reports on the implementation of the techniques developed in this thesis within the CiaoPP system and their experimental evaluation, obtaining encouraging results.

Mar 4, 2021: Alejandro Aguirre has succesfully defended his thesis: "Relational logics for higher-order effectful programs"

PhD defense

The researcher from thr Institute IMDEA Software, Alejandro Aguirre, advised by Prof. Gilles Barthe, has recently defended his thesis successfully: "Relational logics for higher-order effectful programs".

Relational logics are used to express what properties of two executions of the same program or two executions of two different programs have in common. Properties such as program equivalence, non-interference, differential privacy, robustness or sensitivity fall under this umbrella.

Although traditional program verification offers the capability to prove relational properties by using program transformation, ultimately these fall short because they are unable to use the program structure to guide the reasoning. On the other hand, novel logics explicitly designed for relational reasoning are often overly reliant on reasoning synchronously, that is, about programs with similar syntactic structure.

In this study, Alejandro starts by developing Relational Higher-Order Logic (RHOL), a logic to prove relational properties of a pair of pure functional programs that can reason synchronously when the programs have the same syntax, but also has a wide variety of one-sided rules that allows the reasoning to progress when the programs lack this similarity. RHOL also has a companion system, Unary Higher-Order Logic (UHOL) that can be used to prove unary properties (i.e., properties of a single program). Both RHOL and UHOL are based on a standard Higher-Order Logic (HOL). RHOL is not only a logic in its own right, but can also be seen as a framework in which to embed other relational reasoning systems to prove their soundness, as well as a base on top of which to build more expressive logics.

The author demonstrates the versatility of RHOL by using it to support different extensions with the aim of reasoning about probabilistic programs. He first focus on lifting-based properties. Liftings provide a way to erase the computational side effects from logical specifications, so that they can reason about them using standard logics. Some properties that can be proven in this manner are bounds on the probability that the program output satisfies a certain property, or differential privacy. He respectively embed reasoning about these two properties into two novel logics: Higher-Order Union Bound Logic (HO-UBL) and Higher-Order Relational Probabilistic Logic (HO-RPL). He then extends these logics to support reasoning about adversarial properties that specify the behavior of a known program (an oracle) with respect to an unknown program or environment (the adversary). These properties are important concepts in fields such as security or privacy.

Also, in this study, Aguirre considers other related topics. First he looks into proving properties of Markov chains. Many of these properties are inherently relational (e.g., stochastic dominance, recurrence, transience). He adapts the Guarded Lambda Calculus, and the Guarded HOL -a language and logic to reason about infinite streams-, to his setting by extending them with probabilities and developing a relational logic on top of Guarded HOL. Second, he presents a relational logic for higher-order probabilistic programs that is not lifting-based. This requires an extension of the assertion language and an axiomatization of probability theory in the base logic. Finally, Alejandro develops a predicate transformer to reason about expected sensitivity of probabilistic programs.

With this work, the researcher Alejandro Aguirre manages to make a leap in the world of privacy and computer security. He has made several achievements that allow us to learn more about the operation of some programs with probabilistic behaviour.

Feb 26, 2021: Niki Vazou, elected as member of the Interim Board Of Directors of the Haskell Foundation

The researcher of the IMDEA Software Institute, Niki Vazou, has been elected as part of the members of the board of the Haskell Foundation. It is the first time the Foundation decides to create a Board of Directors, so the presence of Vazou is historic.

The Haskell Foundation Board of Directors are responsible for managing and setting the direction of the Haskell Foundation. HF's current board will serve on an interim basis during the launch phase and will manage the establishment of the first full board in early 2021.

Haskell is not “just another programming language”: it embodies a radical and elegant attack on the entire enterprise of writing software. It profoundly influences the world of software for the better. The Haskell Foundation (HF) is an independent, non-profit organization dedicated to broadening the adoption of Haskell, by supporting its ecosystem of tools, libraries, education, and research.

It is not a secret that Niki's research interests include refinement types, automated program verification, and type systems and her goal is to make theorem proving a useful part of mainstream programming. Liquid Haskell is an SMT-based, refinement type checker for Haskell programs that has been used for various applications ranging from fully automatic light verification of Haskell code, e.g., bound checking, to sophisticated theorem proving, e.g., non-interference.

Feb 1, 2021: Dario Fiore, Aikaterini Mitrokotsa, Luca Nizzardo and Elena Pagnin receive the 2020 Premium Award for Best Paper in the IET

Scientific results

The researchers Dario Fiore (IMDEA Software Institute), Aikaterini Mitrokotsa (Chalmers University of Technology), Luca Nizzardo (Protocol Labs Research) and Elena Pagnin (Lund University) receive the 2020 Premium Award for Best Paper in the IET (The Institution of Engineering and Technology) for the paper: "Multi-Key Homomorphic Authenticators."

The technological innovations offered by modern IT systems are changing the way digital data is collected, stored, processed, and consumed. As an example, think of an application where data is collected by some organisations (e.g. hospitals), stored and processed on remote servers (e.g. the Cloud) and finally consumed by other users (e.g. medical researchers) on other devices. On the one hand, this computing paradigm is very attractive, particularly as data can be shared and exchanged by multiple users. On the other hand, it is evident that in such scenarios, one may be concerned about security: while the users that collect and consume the data may trust each other (up to some extent), trusting the Cloud can be problematic for various reasons. More specifically, two main security concerns to be addressed are those about the privacy and authenticity of the data stored and processed in untrusted environments.

While it is widely known that privacy can be solved in such a setting using, e.g. homomorphic encryption, in this work, the authors focus on the orthogonal problem of providing authenticity of data during computation. Towards this goal, their contribution is on advancing the study of homomorphic authenticators (HAs), a cryptographic primitive that has been the subject of recent work.

Homomorphic authenticators (HAs) enable a client to authenticate a large collection of data elements and outsource them, along with the corresponding authenticators, to an untrusted server. At any later point, the server can generate a short authenticator vouching for the correctness of the output y of a function f computed on the outsourced data. The notion of HAs studied in prior work, however, only supports executions of computations over data authenticated by a single user.

In this paper, the authors introduce and formally define multi‐key HAs, they propose a construction of a multi‐key homomorphic signature based on standard lattices and supporting the evaluation of circuits of bounded polynomial depth, and they provide a construction of multi‐key homomorphic MACs based only on pseudorandom functions and supporting the evaluation of low‐degree arithmetic circuits.

In conclusion, this paper provides an innovative solution through the notion of multi‐key HAs. This primitive guarantees that the corruption of one user affects the data of that user only, but does not endanger the authenticity of computations among the other (un‐corrupted) users of the system. Moreover, the proposed system is dynamic, in the sense that compromised users can be assigned new keys and be easily reintegrated.

This paper is an extended version (with additional results and detailed proofs) of the paper "Multi-Key Homomorphic Authenticators" presented by the same authors at ASIACRYPT 2016.

Jan 28, 2021: The paper "Angel or Devil? A Privacy Study of Mobile Parental Control Apps" has won the Research and Personal Data Protection Emilio Aced Award

The researchers Álvaro Feal (IMDEA Networks Institute), Paolo Calciati (IMDEA Software Institute), Narseo Vallina-Rodríguez (IMDEA Networks Institute), Carmela Troncoso (Spring Lab EPFL), and Alessandra Gorla (IMDEA Software Institute) have won the "Emilio Aced Award for the Research and Personal Data Protection" given by the Spanish data protection agency (AEPD), for the paper "Angel or Devil? A Privacy Study of Mobile Parental Control Apps."

Parental control apps are used by parents to monitor the use that their children make of their mobile phones, and to block access to certain features. These apps are highly intrusive by definition, as they can track the actions and movements of the children’s phone (and thus of the child). Therefore, the use of parental control apps can have implications on the privacy of both children and parents.

The study

Existing recommendations by official bodies (such as SIP4 by the European Commission) do not take privacy into consideration, benchmarking only features such as price, capabilities, or usability. To assess such privacy risks, Álvaro, Paolo, Narseo, Carmela and Alessandra relied on a combination of static and dynamic analysis to study 46 parental control apps.

In their work, the researchers found that almost 75% of the apps contain data-driven third-party libraries for secondary purposes (namely advertisement, social networks, and analytic services) and that 67% of the apps share private data without user consent, including apps recommended by public bodies, such as IS4K (Internet Segura For Kids by INCIBE).

They also found that these apps were not transparent about their data collection practices, as 80% of the apps that share data with third parties do not name them in their privacy policy.

Conclusions

The researchers have presented the first multi-dimensional study of the parental control apps ecosystem from a privacy perspective. With their findings they open a debate about the privacy risks introduced by these apps. Does the potential of parental control apps for protecting children justify the risks regarding the collection and processing of their data? This is worrisome, as current legislation (such as the GDPR) protects children’s data from being accessed without clear parental consent. So, given the potential risks of this type of software, they recommend parents to rely on non-technical solutions when possible and to have privacy in mind when choosing one of these applications.

They believe that public bodies should take privacy into account when recommending a given parental control app to raise awareness and encourage developers to follow privacy-by-design principles. The researchers from the IMDEA Software Institute, IMDEA Networks Institute and Spring Lab EPFL stress that it is fundamental to complement current benchmarking initiatives with a security and privacy analysis to help parents to choose the best application while taking these aspects into consideration.

The former researcher of the IMDEA Software Institute, Platon Kotzias, defended his thesis: “A Systematic Empirical Analysis of Unwanted Software Abuse, Prevalence, Distribution, and Economics” in 2019, directed by the Associate Professor, Juan Caballero. Today he works at NortonLifeLock on a wide range of system security topics including malware detection on Android and Windows, application of AI on security topics, and network security.

This month the UPM has resolved the two winners of the Extraordinary Award and Platon's thesis is one of them. In which he investigates how Potentially Unwanted Programs (PUP) can pose significant risks to users’ security and privacy. In particular, he analyzed in both breadth and depth the PUP abuse, prevalence, distribution, and economics.

His PhD shed light on various unknown facets of PUP that affected millions of Internet users. His work has been published in top-tier security conferences like Usenix Security, ACM CCS, IEEE Security & Privacy, and NDSS Symposium.

The four contributions of the thesis

Platon Kotzias performs a systematic study on the abuse of Windows Authenticode code signing by PUP and malware. Building an infrastructure that classifies potentially malicious samples as PUP or malware and using this infrastructure to evaluate 356K samples. He also evaluates the efficacy of Certification Authority (CA) defenses such as identity checks and revocation. CA revocations were equally low for both malware and PUP, so, he concludes that current CA defenses are largely ineffective for PUP.

He measured the prevalence of unwanted software on real consumer hosts using telemetry from 3.9 million hosts. He found PUP installed in 54% of the hosts in their dataset. They also analyzed the commercial pay-per-install (PPI) service ecosystem showing that commercial PPI services play a major role in the distribution of PUP.

In his thesis, Platon performed an analysis of enterprise security and measured the prevalence of both malware and PUP on real enterprise hosts. He used AV telemetry collected from 28K enterprises and 67 industry sectors with over 82M client hosts. Almost all enterprises, despite their different security postures, encounter some malware or PUP in a three year period.

And lastly, he performed an analysis of PUP economics. He proposed a novel technique for performing PUP attribution. Then, he used it to identify the entities behind three large Spanish-based PUP operations and measure the profitability of the companies they operate. The analysis showed that in each operation a small number of people manages a large number of companies, and that the majority of them are shell companies. In the period 2013–2015, the three operations have a total revenue of 202.5M euros and net income of 23M euros. Finally, he observed a sharp decrease on both revenue and income for all three operations starting mid-2014. So, he concludes that improved PUP defenses deployed by various software and security vendors significantly had an impact on the PPI market.

Dec 9, 2020: Dario Fiore is awarded an ERC Consolidator Grant for the PICOCRYPT project

Research Results

The European Research Council (ERC) announced today the awardees of its latest Consolidator Grant call for mid-career researchers. Its funding is part of the EU's current research and innovation programme, Horizon 2020, and worth in total €655 million.

The ERC has granted 327 Consolidator Grants in 2020 to researchers from 23 countries, of which 22 were given to Spanish proposals (consult statistics). The proposal of the IMDEA Software Institute researcher, Dario Fiore, with the project "Cryptography for Privacy and Integrity of Computation on Untrusted Machines (PICOCRYPT)" is one of them.

Dr. Fiore's proposal, planned for five years, has a budget of €2 million, which will allow him to consolidate his research team and make far-reaching advances. PICOCRYPT becomes the third ERC grant awarded to researchers from the IMDEA Software Institute.

The PICOCRYPT project

Due to phenomena like the ubiquity of the Internet and cloud computing, it is increasingly common to store and process data on third-party machines. In spite of its attractive aspects, this trend raises a number of security concerns, including: How to ensure that the results computed by third parties are correct (integrity) and no unauthorized information is leaked (privacy)? The current way to deal with these problems is to trust third parties under legislation guarantees. This approach assumes that third-party machines stay honest all time, even if they get hacked! This is unrealistic and contradicted by the numerous security incidents that are regularly reported.

Instead, Dr. Fiore's view is that it should be possible to store and process data on untrusted machines without risking for privacy and integrity and without the need of trusting these machines. Recent trends in cryptography promise solutions to realize this vision but the existing generation of protocols is limited due to its high costs and its poor support to emerging applications such as data stream processing. The grand challenge of this project is to invent a new generation of cryptographic protocols for commputing securely on untrusted machines in a way that is cost-effective and suitable for future application scenarios.

The solutions provided by the PICOCRYPT project will have the potential to generate a paradigm shift in the way privacy and integrity are ensured and will have an impact on the world of information technology by making delegated computing more secure not only for citizens but also for public and private organizations that, due to current risks, may give up using these services.

Nov 30, 2020: On Algebraic Abstractions for Concurrent Separation Logics, has been accepted at POPL 2021

Research Results

The researchers František Farka, Aleksandar Nanevski, Anindya Banerjee (from the IMDEA Software Institute), Germán Andrés Delbianco (Nomadic Labs), and Ignacio Fábregas (Universidad Complutense de Madrid) have recently published "On Algebraic Abstractions for Concurrent Separation Logics", that has been accepted at POPL 2021.

Concurrent separation logic is a logic for verification of stateful programs. This logic is distinguished by transfer of state ownership upon parallel composition of threads. The semantics ownership transfer is given by the algebraic structure of partial commutative monoids(PCMs). Extant research considers ownership transfer primarily from the logical perspective while comparatively less attention is drawn to the symbolic manipulation on the level of specifications expressed in the assertion language.

This paper provides an algebraic formalization of assertion language for ownership transfer in concurrent separation logic by means of structure-preserving partial functions (i.e., morphisms) between PCMs, and an associated notion of separating relations.That is, when verifying software, they can assert specifications in symbolic languages of standard mathematics; the only concession they are forced to is relaxation from total domains to partial ones.

Morphisms, that is structures preserving maps, are a standard concept in algebra and category theory. However, morphisms haven't seen ubiquitous use in separation logic before. Separating relations are binary relations that generalize disjointness and characterize the inputs on which morphisms preserve structure. The two abstractions facilitate verification by enabling concise ways of writing specs, by providing abstract views of threads' states that are preserved under ownership transfer, and by enabling user-level construction of new PCMs out of existing ones.

The presented work constitutes a novel approach to assertion language of separation logics as the algebra of PCMs, their morphisms and constructions has not been considered before in this context.

Nov 20, 2020: Manuel Hermenegildo gives the Opening Keynote, on "Cost Analysis of Smart Contracts via Parametric Resource Analysis," at the top conference on Static Program Analysis SAS 2020

Research Results

IMDEA Software Institute researcher, Manuel Hermenegildo, gives the Opening Invited Talk at the 27th Static Analysis Symposium (SAS'20), on "Cost Analysis of Smart Contracts via Parametric Resource Analysis," work co-authored with Víctor Pérez, Maximiliano Klemen, Pedro López-García and José Francisco Morales.

This line of research is motivated by the fact that, in blockchains, contract execution and storage are replicated across large numbers of nodes, and this makes resource consumption an important concern. The few cost analyzers that exist for smart contracts are for specific platforms and languages. However, blockchain platforms present significant variability, also over time.

Parametric Resource Analysis (also referred to as User-Defined Resource Analysis) is a generic approach, proposed by the IMDEA Software Institute team, for developing analyzers that infer safe bounds on different resources and with different resource models. In the talk, Manuel Hermenegildo reviews this approach and explores its application to the static inference of gas and storage consumption bounds for smart contracts, reporting on a concrete case study: developing an analyzer for the Tezos platform and its Michelson language. The results show that the approach is an effective method for the rapid development and maintenance of cost analyzers for smart contracts.

The Parametric Resource Analysis approach was awarded the 10 year Test-of-Time Award at the 2017 International Conference on Logic Programming, the premier conference in the area.

IMDEA Software's CiaoPP framework implements this approach and allows its application to different programming languages, by translation into a Horn clause-based intermediate representation.

The series of International Static Analysis Symposia (SAS) serves as the primary venue for presentation of theoretical, practical, and application advances in this area. This edition of SAS is co-located with SPLASH'20 in an online form, coordinated from Chicago, USA, from November 18 to November 20, 2020. SPLASH embraces all aspects of software construction and delivery, to make it the premier conference on the applications of programming languages - at the intersection of programming languages and software engineering.

The associated work is conducted in the context of the collaboration of the Tezos foundation and Nomadic labs with the IMDEA Software Institute.

Oct 21, 2020: Around 80 people attended the virtual 15th REDIMadrid 2020 Conference

The 2020 edition of the REDIMadrid Conference has been completely virtual due to the COVID-19, but efforts have been made to make the conference very interesting, shorter in order to continue to attract a very determined audience.

Blanca Gutiérrez, Communication Manager of the IMDEA Software Institute, began the conference with a brief introduction and was followed by Manuel Carro, Director of the IMDEA Software Institute, who gave the conference's opening speech.

Manuel, spoke about the origin of the network as well as high-speed networks that offer services to the educational and scientific community. In this sense, he stated that teleworking, forced by the arise of the pandemic, would not have been possible without fibre optic networks such as REDIMadrid. "The leap into the digital world and into education has come to stay despite the fact that regulations must also be updated" he confirmed.

"The state of REDIMadrid. Present and Future" was the first presentation, given by César Sánchez, director of REDIMadrid and Associate Research Professor at the IMDEA Software Institute, in which he commented that REDIMadrid is the last mile of the RedIRIS network in Madrid as part of the European GEANT network.

David Rincón, Coordinator of REDIMadrid, spoke about the Denial of Service (DDoS) attacks in the educational environment that have resulted with the tendering of a software to mitigate these attacks. "This is a new service offered by REDIMadrid which has had to be adjusted to the change in profile caused by COVID-19" he said of the GENIE tool. The traffic is mitigated before it reaches the institutions, so the network's clients are protected.

The following talk: "The Madrid Quantum Network", was given by Vicente Martín, professor of the Computer Science Faculty, UPM. His presentation was based on the quantum network that is being deployed in Madrid as part of the OpenQKD project. "Quantum computing is characterised by the basic information unit Qubit. Qubits communication consists of the propagation of photons and, when these are in transit, they cannot be touched without modifying their characteristics, for this reason they cannot be intercepted in transit and this is what gives the technology total security" confirms Vicente.

After the talk on quantum communications came the WhiteBox colloquium in which the following took part: Diego Nuevo, Network & Data Center Arquitect at Axians; Víctor López, technology expert in the General Directorate of Systems and Networks at Telefónica; and Óscar Rebollo, engineer at REDIMadrid. The situation of integration, costs and support of the whiteboxes was discussed, as well as the state of penetration of this equipment in the clients' networks, exemplified by the TIP project (Telecom Infra Project).

The conference continued with the talk "The Lockdown Effect: Implications of the COVID-19 Pandemic on Internet Traffic", based on a publication that will be presented soon and whose authors are Juan Tapiador, professor of computer science at UC3M, and Narseo Vallina-Rodríguez, Research Assistant Professor at the IMDEA Networks Institute. REDIMadrid has contributed to this study by providing traffic data.

The next to participate was Marta Vázquez, from INTECCA-UNED, who presented the AVIP application. "From COVID-19, videoconferencing has become compulsory at the UNED and thanks to the application's scalable architecture, it has been possible to absorb the large increase in traffic, which has peaked at over one hundred thousand users on some days".

And finally, Gibran Gómez, researcher at the IMDEA Software Institute, gave a talk on "Malicious TLS Traffic Detection using Unsupervised Machine Learning". According to Gibran "there are few protocols that send clear information, so attacks on protocols that use encryption such as TLS are beginning to increase. Machine Learning (ML) techniques are used to detect and combat MITM and malware attacks and the system developed detects them and generates alerts".

Oct 9, 2020: Elena Gutiérrez's defended her thesis: "New Perspectives on Classical Automata Constructions"

Research Results

The researcher of the IMDEA Software Institute, Elena Gutiérrez, supervised by Pierre Ganty, defended recently her thesis titled: "New Perspectives on Classical Automata Constructions".

She focuses in this thesis on the models of finite-state automata, pushdown automata and context-free grammars. These models have been proved useful for a wide number of applications such as program verification, natural language processing tasks or digital-image compression techniques. These applications strongly rely on language-theoretical notions where, still today, many questions are open.

The goal of this thesis is to give new theoretical perspective on a collection of open problems, that are at the core of classical automata constructions and well-established algorithms.

The underlying mathematical tool to approach these questions are equivalence relations on words as abstractions of languages. So, she studies three main questions:

In this thesis, she aims to get a better understanding of the language-theoretical basis of the double-reversal method and its connection with the partition-based techniques. As a result, we provide a uniform framework of deterministic automata constructions based on finite-index equivalences on words that allows us to give a new simple proof of the double-reversal method and shed light on the relation between this algorithm and the partition-based techniques.

Her main contribution is to provide an infinite family of PDAs defined over a singleton alphabet that allows her to extract lower bounds on the number of grammar variables of the smallest CFG.

To sum up, "in this dissertation we leverage equivalences on words as abstractions of languages. More pointedly, these abstractions are regular approximations of languages. Our results regarding finite-index congruences encourages the study of other kinds of regular approximations of context-free languages and the use of our framework to define congruence-based automata constructions for their finite representation", appointed Elena. On the other hand, her work on the Parikh equivalence assumption shows that, despite being a relaxed version of language equivalence that enables the analysis of certain complex systems, when comparing PDAs against CFGs the situation is not different to that of language equivalence. And also, sets the basis for future directions on the extension of Parikh's Theorem to weighted automata.

Oct 5, 2020: FPGA-Accelerated Analytics: From Single Nodes to Clusters

Research Results

The researchers Zsolt István (IMDEA Software Institute), Kaan Kara, (Oracle Labs), and David Sidler (Microsoft Corporation) have published the book "FPGA-Accelerated Analytics: From Single Nodes to Clusters".

Today datacenters that host data-intensive applications used in online services and machine learning need to store and process data that increases at an exponential rate. Data processing and management applications have become increasingly distributed and this has lead to new data movement bottlenecks at various levels of software and hardware architecture.

The authors survey recent research on using reconfigurable hardware accelerators, namely, Field Programmable Gate Arrays (FPGAs), to accelerate analytical processing. Such accelerators are being adopted as a way of overcoming the recent stagnation in CPU performance because they can implement algorithms differently from traditional CPUs, breaking traditional trade-offs.

Zsolt, Kaan and David discuss the benefits of using FPGAs in the context of analytical processing, both as an accelerator within a single node database and as part of distributed data analytics pipelines. They also present guidelines for accelerator design in both scenarios, as well as, examples of integration within full-fledged Relational Databases.

Finally, they highlight future research challenges in programmability and integration, and cover architectural trends that are propelling the rapid adoption of accelerators in datacenters and the cloud.

Sep 10, 2020: Liquid Haskell as a GHC Plugin, a superior solution to the old approach

Research Results

The researchers Alfredo Di Napoli, Andres Löh (both from Well-Typed LLP), Ranjit Jhala (University of California at San Diego) and Niki Vazou, from the IMDEA Software Institute have presented: “Liquid Haskell as a GHC Plugin” at the Haskell Implementors’ Workshop (HIW 2020) in ICFP 2020.

Liquid Haskell is a system that extends GHC with refinement types. Constraints arising from the refinement types are sent to an external automatic theorem prover such as z3. By employing such additional checks, one can express more interesting properties about Haskell programs statically.

Up until now, Liquid Haskell has been a separate executable that uses the GHC API, but would run on Haskell files individually and just say “SAFE” or “UNSAFE”. If “SAFE”, one could then proceed to compile a program normally.

Recently, the researchers have rewritten Liquid Haskell to now be a GHC plugin. The main advantages of this approach are:

When checking source files, Liquid Haskell requires information about the constraints already established for dependent libraries. Previously, these had to be hand-distributed for selected modules with Liquid Haskell itself. Now, they become part of normal GHC interface files and can be distributed for arbitrary user packages via Hackage.

In this work, the researchers present the Liquid Haskell plugin workflow and why they think it is superior to the old approach. They also discuss the implementation of the plugin: it is interesting because it does not neatly fit into the plugin categories currently provided. Morally, Liquid Haskell typechecks the code, but in order to generate constraints to feed to the prover, it must access (unoptimised!) core code. They explain the final design, and some of the iterations they needed to get there.

Aug 31, 2020: Pierre Ganty, Elena Gutiérrez and Pedro Valero publish: A Quasiorder-based Perspective in Residual Automata

Research Results

The researchers Pierre Ganty, Elena Gutiérrez and Pedro Valero have recently published "A Quasiorder-based Perspective in Residual Automata" presented at MFCS 2020 (Mathematical Foundations of Computer Science) that took place from the 24th-28th of August. The three researchers of the IMDEA Software Institute propose a different view on a class of finite-state machines of great relevance in practice, the so-called "Residual Automata".

To give a little bit of context, residual automata are classical finite-state automata (FSAs for short), i.e., transition systems with a finite number of states that are used to represent the so-called regular languages, one of the most studied objects in formal language theory.

Actually, finite-state automata are finite representations of regular languages, and this might not be illuminating but it is rather helpful when the languages they represent are infinite!

Going back to our objects, residual automata, among the general FSAs, enjoy interesting properties that make them useful in applications such as grammar inference.

The main goal of grammar inference is to find a target language using a finite set of examples of words in the language. In other words, grammar inference is a machine learning technique by means of which we learn a (possibly infinite) language of words given only a finite number of them.

In this context, residual automata are useful tools as it has been proven that they can represent very concisely (and finitely, since they are FSAs) the target language.

In this paper, they study the properties of residual automata from a theoretical point of view.

Namely, we use quasiorders as a mathematical tool to give a new perspective on the construction of residual automata. Quasiorders are relations between the elements of a set satisfying some properties. For instance, given the set of all natural numbers N, the relation ≤, which relates two elements x and y if x ≤ y, is a quasiorder on N.

In this work, they define quasiorders on words and use them to construct residual automata. By using different quasiorders we construct different residual automata, including the minimal one for some given language.

Concretely, we present a new residualization operation and a generalized Brzozowski's method for building the minimal residual automaton for a given language. We also leverage this technique to offer a new perspective on NL*, an online learning algorithm for residual automata.

Aug 28, 2020: Non-Malleable Secret Sharing against Bounded Joint-Tampering Attacks in the Plain Model

Secret sharing schemes enables a dealer to split a secret into a set of shares, in such a way that certain authorized subsets of shareholders can reconstruct the secret, whereas all unauthorized subsets cannot.

Non-malleable secret sharing schemes (Goyal and Kumar, STOC 2018) additionally require that if the shares have been maliciously modified then the reconstructed secret is completely unrelated one.

The researchers Gianlunca Brian (Sapienza, University of Rome), Antonio Faonio (IMDEA Software Institute), Maciej Obremski (National University of Singapore), Mark Simkin (Aarhus University), Daniele Venturi (Sapienza, University of Rome) have worked jointly to create "Non-Malleable Secret Sharing against Bounded Joint-Tampering Attacks in the Plain Model" paper that was accepted at Crypto 2020.

In their work, they construct non-malleable secret sharing schemes secure against attackers that can maliciously modify the shares more than once in the so-called joint-tampering model.

In particular, assuming one-to-one one-way functions, they obtain:

– A threshold secret sharing scheme secure under attacks where the attacker commits to a partition of the shares, and keeps tampering jointly with the shares within such a partition (so-called selective partitioning).

– A secret sharing scheme for general access structures which tolerates joint tampering with subsets of the shares of size O(√log n), where n is the number of parties. The scheme is secure even if the attacker is allowed to adaptively change the partitions (so-called semi-adaptive partitioning).

Their research lies a new technique showing that every one-time statistically non-malleable secret sharing against joint tampering is in fact leakage-resilient non-malleable (i.e., the attacker can leak jointly from the shares prior to tampering). This may be of independent interest, and in fact they show it implies lower bounds on the share size and randomness complexity of statistically nonmalleable secret sharing against independent tampering.

Jul 30, 2020: Pedro Valero defended successfully his thesis: “On the use of Quasiorders in Formal Language Theory”

Research Results

The researcher from the IMDEA Software Institute Pedro Valero, supervised by Pierre Ganty, defended his PhD thesis with the title “On the use of Quasiorders in Formal Language Theory”, on the 20th of July. He submitted his thesis as partial fulfillment of the requirements for the degree of Doctor of Philosophy in Software, Systems and Computing.

Quasiorders on words, i.e. binary relations between words, have proven useful for reasoning about formal languages from a theoretical perspective. For instance they have been used to characterize the class of regular languages and for showing that all maximal solutions of certain systems of inequalities on languages are regular.

In his work, Pedro shows that quasiorders also have practical applications by placing them at the core of several efficient algorithms.

More precisely, in his thesis, Pedro uses quasiorders on words to offer a new perspective on two well-studied problems from Formal Language Theory: deciding language inclusion, with applications to searching on compressed text, and manipulating the finite automata representations of regular languages.

The Language Inclusion Problem

The thesis considers the language inclusion problem L1 ⊆ L2, where L1 is regular or context-free and L2 is regular.This problem is solved by checking whether an over-approximation of L1 is included in L2, showing that the language inclusion problem is decidable whenever the over-approximating function satisfies a completeness condition (i.e. its loss of precision causes no false alarm) and prevents infinite ascending chains (i.e. it guarantees termination of least fixpoint computations).

Such over-approximation of L1 is defined using quasiorder relations on words where the over-approximation gives the language of all words “greater than or equal to” a given input word for that quasiorder. In his thesis, Pedro presents a range of quasiorders in order to systematically design decision procedures for different language inclusion problems such as regular languages into regular languages or into trace sets of one-counter nets and context-free languages into regular languages.

Some of the obtained inclusion checking procedures correspond to well-known algorithms, like the so-called antichains algorithms, while others correspond to novel algorithms such as the presented greatest fixpoint language inclusion check, which relies on quotients of languages.

Searching on Compressed Text

Secondly, the thesis instantiates the quasiorder-based framework for the scenario in which L1 consists on a single word generated by a context-free grammar and L2 is the regular language generated by an automaton. The resulting algorithm can be used for deciding whether a grammar-compressed text contains a match for a regular expression.

This algorithm is then extended in order to count the number of lines in the uncompressed text that contain a match for the regular expression. Remarkably, this extension runs in time linear in the size of the compressed data, which might be exponentially smaller than the uncompressed text.

Furthermore, Pedro's thesis proposes efficient data structures that yield optimal complexity bounds and an implementation –zearch– that outperforms the state of the art, offering up to 40% speedup with respect to highly optimized implementations of the standard decompress and search approach.

Residual Finite-State Automata

The last technical contribution of this thesis is a framework of finite-state automata constructions based on quasiorders over words that provides new insights on residual finite-state automata (RFA for short).

This framework is used to present a generalization of the double-reversal method for RFAs along the lines of the one for deterministic automata and to offer a new perspective on NL∗, an on-line learning algorithm for RFAs. These results evidence that quasiorders are fundamental to residual automata in the same way congruences are fundamental for deterministic automata.

Jul 2, 2020: Learning secrets and models from execution time

Research Results

The researcher of the IMDEA Software Institute, Pepe Vila, has sucessfully defended his PhD thesis titled: "Learning secrets and models from execution time". Professor Boris Köpf (on leave researcher of the Institute and researcher of Microsoft Research Lab at Cambridge) was his advisor.

In his work he studies some of the problems arising on computer systems that leak information through execution time. They study several instances of how these leaks can be used to both learn secrets—of a confidential computation—and models—of an underlying component—, providing examples that violate previous assumptions about systems’ security or about the attackers’ capabilities.

He studies in particular, time leakage under three different scenarios, providing multiple independent contributions in each of them:

• First, he shows that event-driven software systems are susceptible to side- channel attacks. The key observation is that event loops form a resource that can be shared between mutually distrusting programs. Hence, con- tention of this resource by one program can be observed by the others through variations in the time the latter processes take for dispatching their events. We exploit two different shared event loops in the Chrome web browser, and use the information obtained in three different attacks: for web page fingerprinting, for keystroke detection, and for a cross-origin covert channel.

• Then, he reveals that the contributions are both theoretical and practical. On the theoretical side, we formalize the problem of finding minimal eviction sets, a key primitive for several microarchitectural attacks, and devise novel algorithms that improve the state-of-the-art from quadratic to linear. On the practical side, we perform a rigorous empirical analysis that exhibits the conditions under which our algorithms succeed or fail.

• Finally, he presents a practical end-to-end solution for inferring deterministic cache replacement policies using off-the-shelf techniques for automata learning and program synthesis. The enabling contribution is a chain of two abstractions: a clean interface to the hardware cache replacement poli- cies based on timing measurements on a silicon CPU; and a mapper that exposes a membership oracle to the cache replacement policy abstracting away the details regarding cache content management.

In conclusion, the results of Pepe Vila's thesis constitute an evidence that better models and quantification methods -for both software and hardware systems-, are required in order to reason about the soundness and trade-offs of security countermeasures; and provide a basis for principled countermeasures against, or paths for further improving the efficiency of, several side channel attacks.

Jun 11, 2020: Ignacio Cascudo and Bernardo David have published ALBATROSS: publicly AttestabLe BATched Randomness based On Secret Sharing

The researchers Ignacio Cascudo (IMDEA Software Institute) and Bernardo David (IT University of Copenhagen) have recently published "ALBATROSS: publicly AttestabLe BATched Randomness based On Secret Sharing".

ALBATROSS is a family of multiparty randomness generation protocols with guaranteed output delivery and public verification that allows to trade off corruption tolerance for a much improved amortized computational complexity.

Their basic stand alone protocol is based on publicly verifiable secret sharing (PVSS) and is secure under in the random oracle model under the decisional Diffie-Hellman (DDH) hardness assumption. They also address the important issue of constructing Universally Composable randomness beacons (that can be used in more complex environments), showing two UC versions of Albatross: one based on simple UC NIZKs and another one based on novel efficient "designated verifier" homomorphic commitments. Interestingly this latter version can be instantiated from a global random oracle under the weaker Computational Diffie-Hellman (CDH) assumption.

An execution of ALBATROSS with n parties, out of which up to t = (1/2 − ε) · n are corrupt for a constant ε > 0, generates Θ(n^2) uniformly random values, requiring in the worst case an amortized cost per party of Θ(log n) exponentiations per random value. On Cascudo and David paper they significantly improve on the SCRAPE protocol, which required Θ(n^2) exponentiations per party to generate one uni- formly random value. This is mainly achieved via two techniques: first, the use of packed Shamir secret sharing for the PVSS; second, the use of linear t-resilient functions (computed via a Fast Fourier Transform-based algorithm) to improve the randomness extraction.

The main application of these protocols is in proof-of-stake blockchains, which, every certain period of time, requires to elect a "leader" among the users of the protocol, and where this selection must not be possible to be biased, and the correctness of this process needs to be able to be verified publicly.

Jun 1, 2020: Learning Replacement Policies from Hardware Caches towards more secure systems

The IMDEA Software Institute researchers Pepe Vila, Pierre Ganty and Marco Guarnieri, and Boris Koepf, from Microsoft Research, are the authors of the recent paper “CacheQuery: Learning Replacement Policies from Hardware Caches” accepted at the 41st ACM SIGPLAN Conference on Programming Language Design and Implementation (PLDI 2020).

Caches are small and fast memories that sit between the CPU and the main memory (DRAM) of computers. Their main goal is to speed up computations by reducing the time it takes to load and store data, and since their capacity is limited, they must anticipate which data is going to be used in the near future. The better this prediction, the better the performance.

Thus, the cache replacement policy is the logic that decides which data is kept in the memory cache and which is replaced to make room for more useful data. It is a critical component for the performance of modern computers.

In most modern processors these policies are not documented, and since they have a huge performance impact, the absence of precise models makes it very difficult to predict and analyze the behavior and security of programs.

“We lack precise models of our hardware. With our approach, we close this gap, and we allow other people to understand how the policy optimizes certain workloads, so that they can predict the timing behavior of critical systems (i.e., cars or planes), calculate limits on the information leakage of cryptographic programs, or write more accurate hardware simulators” comments Pepe Vila, predoctoral researcher of the IMDEA Software Institute.

Transparency, is the first step towards improving the security and safety of computer systems. In this sense, the researcher of the Institute, Marco Guarnieri, says that: “microprocessors and memories are central components of our computing infrastructure. Security vulnerabilities in these components may result in attacks affecting any program running on top of them. To assess and study the security of microprocessors and memories, researchers need high-level models documenting and describing their behaviors. Unfortunately, many crucial details of how these components work are undocumented. We see our research as a first step towards automatically generating such high-level models from hardware measurements and, ultimately, towards more secure systems”.

Through this partnership, the IMDEA Software Institute and BBVA have created a joint framework to research the use of this technology in the development of digital solutions that make it possible to harness data’s potential while also ensuring that users’ data remain private, anonymous and secure.

The agreement is especially relevant in the current context marked by the coronavirus crisis, which is demonstrating the importance of having robust systems to safeguard the privacy and security of data. On the one hand, this is due to the rise of cyber-attacks in recent weeks in which cyber criminals are taking advantage of users’ increased use of digital channels during the lockdown. And on the other, due to the interest sparked by the creation of COVID-19 tracking apps that respect data privacy, for which technologies of this kind could be very useful.

With this new partnership, both institutions will explore the application of a series of cryptographic techniques in the financial sector - techniques that make it possible for data to be shared and analyzed without exposing their content to third parties thanks to algorithms, protocols and encryption systems. These technologies, known as PET, or privacy-enhancing technologies are one of the fields in which the IMDEA Software Institute specializes, as well as one of the areas of interest that BBVA researches in its Research and Patent area.

Within this group of technologies, one that has the greatest potential and which will be the main subject of the new team’s study is zero knowledge proofs (ZKP). This technology uses cryptographic algorithms to make it easier to verify the accuracy of information, without having to share the data that comprise it. This way, it can help to create data-based solutions in which customers’ sensitive data is not exposed to third parties (as it is not necessary to share the data with them to prove that they are accurate).

Thanks to this agreement, both institutions are combining their capacities and knowledge in these areas. The goal is for the research to translate into tangible advances that make it possible to transfer the benefits of this technology to the financial sector, the corporate world, the scientific community and society as a whole.

To do so, in the first stage, the joint team will research how to solve some of the current challenges that the roll-out of this technology is still facing in order to share the results with the scientific community to foster progress in this discipline. Some of these challenges involve its integration with the current communication systems that companies are using, or the lack of common standards for the use of cryptographic protocols, which complicates its adoption on a large scale.

BBVA and the IMDEA Software Institute will also work on a series of real use cases identified in the financial sector, as well as the development of viable prototypes that can be incorporated in the digital products and services offered to BBVA customers.

Mar 11, 2020: Pepe Vila explains at RootedCON the automata theory for reversing modern CPUs

The pre-doctoral researcher at the IMDEA Software Institute, Pepe Vila, participated at RootedCON 2020 last 7th of March giving a talk titled ‘The '80s never died: automata theory for reversing modern CPUs’ (view presentation). He explained his latest paper developed with the support and of the researchers Pierre Ganty and Marco Guarnieri, from IMDEA Software Institute, and Boris Köpf, from Microsoft Research, 'CacheQuery: Learning Replacement Policies from Hardware Caches' which reveals the previously unknown implementation of cache replacement policies used in modern processors.

Understanding the timing behavior of modern CPUs is crucial for optimizing code and for ensuring timing-related security and safety properties. Unfortunately, the timing behavior of modern processors depends on subtle and poorly documented details of their microarchitecture, which has triggered laborious efforts to reverse-engineer microarchitectural details. Cache replacement policies have received special attention, because they control the content stored in the memory hierarchy and hence heavily influence execution time.

In the paper, which has been accepted into PLDI'20 (Conference on Programming Language Design and Implementation), researchers from the IMDEA Software Institute and Microsoft Research present an end-to-end solution for automatically learning cache replacement policies from hardware time measurements. Their contribution is based on two main contributions: a tool, called CacheQuery, that provides an interface to any set in the cache hierarchy, freeing the user from having to deal with intricate details such as address translation, index mapping, interference from other cache levels or measurement noise; and, an algorithm, called Polka, that provides an abstract automaton for the cache replacement policy, and exploits various symmetries that make the automaton learning techniques applicable to the problem. In addition, they have been able to synthesize programs to automatically derive readable descriptions of the learned replacement policy.

In the experimental phase, their tests have been successful in learning several cache replacement policies used in Intel's latest processors, including two previously undocumented policies.

Feb 20, 2020: Almost 100 students from various schools came to 'Breaking Codes: Women and Girls in Science'.

The 11th of February, on the occasion of the International Day of Woman and Girl in Science, the IMDEA Software Institute organised the conference 'Breaking Codes: Women and Girls in Science' with the support of various researchers from the Institute, as well as other centres on the Campus, such as the Center for Biomedical Technology CTB.

Blanca Gutiérrez, Communication Manager at the IMDEA Software Institute, was in charge of opening the conference in which she explained the importance of research for the advances in society and highlighted the need to promote scientific and research vocations in women and girls in a sector that is mainly masculine.

The first workshop was on reconstruction of neurons. Marta Domínguez and Marta Turégano, researchers at the CTB showed what a neuron is and helped the young women in the audience to differentiate between the different parts of a neuron: synapses, mitochondria, as well as spinal apparatus and myelin sheaths. In addition, they showed the software they use in their laboratory by which it automatically detects each differential element to be studied.

The cryptography workshop was led by three researchers from the IMDEA Software Institute: Anaïs Querol, Elena Gutiérrez and Isabel García. The first to open the workshop was Anaïs, who spoke about the origin of ciphered messages and how to encrypt and decrypt them. On the other hand, Isabel explained how to break mono-alphabetic ciphers. And finally, Elena delved into the workings of the enigma machine and how ciphers were broken at Bletchley Park.

After the workshops, the wikiton began. We divided the audience into groups and gave them a choice between seven Spanish scientists from different fields to create, through information provided, their page on Wikipedia.

The day ended with the 20 questions of the scientific trivial in which the knowledge acquired during the day was tested, as well as the general culture of the public.

Feb 12, 2020: Three days of hackathon, over 24 hours of coding and three awards. This is how chainrEaction ended

The first blockchain hackathon for environmental action in Spain, organized by the IMDEA Software Institute and EIT Digital, whose awards were sponsored by the Tezos Foundation, ends with 11 award-winning participants from the three groups selected by the jury.

ChainrEaction had overall 26 participants, from 10 different countries. 10 of them were university students, 12 master students and 8 doctoral students. Almost 95% of the people respondents have interest (answering yes or maybe) in working at the IMDEA Software Institute. 50% of them punctuated 4 or 5 out of 5 according to their interest in a research-oriented career before chainrEaction, and this figure increased by 22,2% after the hackathon.

Three intensive days that began with presentations, and the introduction to the event given by Blanca Gutiérrez, Communication Manager, as well as Zsolt István, Assistant Research Professor, as part of the chanrEaction organizing committee of the IMDEA Software Institute. The morning continued with an inspiring talk by David Dao, Founder of Forest X, on "Decentralized Sustainability: Beyond the Tragedy of the Commons with Smart Contracts (and AI)".

Daniel Pérez, Chief Technology Officer at the Imperial College London, gave a tutorial on Ethereum as a mentor of chainrEaction that was a valuable, practical and challenging information for participants.

The second talk of the first day was given by Chrysa Stathakopoulou, a chainrEaction mentor and PhD student at ETH Zurich, on how to use and apply blockchain technology in businessess.

Meanwhile, Matteo Campanelli, postdoctoral researcher at the IMDEA Software Institute, organizer of chainrEaction and also a mentor, presented the second tutorial of the day on the chain code of Fabric Hyperledger and websites to interact with it.

During the last part of the day the participants presented their ideas, selected the seven teams that were formed and started coding.

The second day began with an interesting talk by Matej Šima, CEO os Stove Labs, who gave a beginner's guide to SmartContracts through Tezos technology. For the rest of the day participants had the opportunity to code practically the whole day, as well as to listen to the two EIT Digital Student Ambassadors, Renato Pinto and Cristina Ríos.

On the morning of the third day the seven groups were able to finish preparing their sustainable solutions. From 11 to 13 they presented their results to the jury made up of: the director of the IMDEA Software Institute, Manuel Carro; the director of the EIT Digital Co-Location Center, Jesús Contreras; the advisor to the Regional Ministry of Science, Universities and Innovation, Juan Jiménez; representative of the Blockchain Competence Center of Telefónica, María Teresa Nieto; the Head of Blockchain at iecisa, María Salgado; and the CEO of Stove Labs, Matej Šima.

Dec 30, 2019: César Sánchez: The ElasTest project improves the efficiency and effectiveness of the testing process and the overall quality of large software systems

Research Results

The researcher of the IMDEA Software Institute, César Sánchez, talks about the ElasTest project in a video interview published on the Youtube channel of the Institute.

ElasTest is a Project funded by the European Union under the Horizon 2020 program. The main goal of the project is to provide a tool and an infrastructure to test end to end elastic applications. The modern cloud applications back ends are essentially elastic which means that they demand, they consume, they need more resources when they have, for example, more users, more access in the service, so this applications are notoriously difficult to test and to provide a software reliability which is a big challenge for mid-size and small enterprises. The project essentially is building an infrastructure to do this end to end testing and the different circumstances, for example: different users, many users at a time, different browsers, failures in the network and such, even failures in the components on the application itself.

The role of the IMDEA Software Institute in the project ElasTest has been to one, test security in the application and the other is to provide monitoring that allows to describe the test in an easier manner and to assess the test dynamically. César Sánchez ends the interview saying that: “All in all, I think that the ElasTest project has been very successful in both academic and in terms of developing the tool.”

Dec 27, 2019: Marco Guarnieri: “Using Spectector, we detected subtle bugs in the way countermeasures against speculative execution attacks are placed by major compilers”

Research results

Micro-architectural attacks, like the recently discovered Spectre and Meltdown attacks, exploit critical vulnerabilities in modern processors to compromise a system's security.

These attacks affect all modern general-purpose processors (such as those used in our computers). Concretely, they can bypass common security defenses at the software level by exploiting hardware side-effects.

In Marco Guarneri’s research, he developed tools for better understanding how micro-architectural attacks work. He then leverages this understanding to design new defense techniques against these attacks.

As a concrete example, Marco Guarnieri, José F. Morales and Andrés Sánchez, from the IMDEA Software Institute, Boris Köpf, from Microsoft Research, and Jan Reineke, from Saarland University recently developed SPECTECTOR, an automated technique for determining whether programs are vulnerable to a specific class of micro-architectural attacks called speculative execution attacks.

“Using Spectector, we detected subtle bugs in the way countermeasures against speculative execution attacks are placed by major compilers. These bugs may result in insecure programs or inefficient programs” ended Marco.

Dec 26, 2019: Liquidate your Assets has been presented to POPL2020

Research results

Niki Vazou, researcher at the IMDEA Software Institute, Martin A.T. Handley and Graham Hutton, from the University of Nottingham, UK have developed “Liquidate your Assets” a paper they presented to POPL2020 . You may find it here.

Liquid Haskell is an extension of Haskell’s Type system that allows annotating types with refinement predicates. It is great for ensuring correctness of code, but it can also be used to improve the performance of code.

Vazou, Handley and Hutton have designed and implement a system that allows Liquid Haskell to be used to formally reason about the resource usage of pure Haskell programs. Moreover, it supports reasoning about correctness and efficiency properties in a combined, uniform manner. "Our system takes the form of a library and requires no modifications or extensions to the compiler" comments Niki Vazou.

They have proven that their library’s approach to cost analysis is correct with respect to an underlying model of execution cost using the metatheory of Liquid Haskell.

In the end, they have demonstrated the applicability of their library on a wide range of case studies, ranging from standard sorting algorithms to sophisticated relational cost properties.

Dec 20, 2019: Luca Nizzardo’s thesis: "Cryptographic Techniques for the Security of Cloud and Blockchain Systems" has won the UPM extraordinary award 2017-2018

Luca Nizzardo, was a PhD student of the IMDEA Software Institute and his thesis “Cryptographic Techniques for the Security of Cloud and Blockchain Systems” defended in 2018 was directed by the Associate Professor, Dario Fiore. Nowadays he works for Protocol Labs helping to build protocols, systems, and tools to improve how Internet works.

This month the UPM has resolved the two winners of the Extraordinary Award and Luca’s thesis is one of them. In which he investigates how to enforce the honest behavior of parties involved in a digital interaction over the Internet. In particular, considering two emerging paradigms in this setting: Cloud computing and E-commerce.

The Human interactions often involve people who have different and sometimes contrasting interests, like buyers and sellers or consumers and providers. For what regards physical interactions, the society has developed during the years many different ways to protect users against misbehaviors. Nevertheless, when this communication happens in the digital world through the Internet, where people do not meet or even know each other, such a protection is more challenging to obtain, and additional digital tools are needed in order to defend users.

Two main security concerns that have given attention by the research community are those about the privacy and authenticity of the data stored and processed in untrusted environments. Intuitively, for privacy a Client does not want the server to learn any information about the outsourced data. For authenticity, the Client instead wants to be sure that the Cloud computed correctly on the outsourced data.vIn his thesis he focused on this second problem, advancing the study of homomorphic authenticators. In homomorphic authenticators a Client C outsources authenticated data to the Cloud. Later on, a third entity (the Verifier) can ask the Cloud to compute a function f over the Client’s outsourced data. Using a special procedure, the Cloud can provide the Verifier with an authenticator for the output of the function, which allows the Verifier to check the validity of the computation queried.

The contribution of the thesis addresses three different aspects of homomorphic authenticators: definitions, efficiency and functionalities.

First, it introduces a new security model which is stronger and easier to deal with compared with the existing one, along with two compilers which allow one to go from the old model to the new one. Second, it provides the first linearly homomorphic signature scheme whose verification keys have size sublinear in that of the outsourced dataset. Third, it formalizes the notion of homomorphic authenticators for functions which take inputs authenticated using different keys, providing concrete constructions both in the case of private and public verification.

For what regards E-commerce and, more in general, the possibility of transferring value through the Internet, this work is focused on achieving fair exchange by profiting of the Blockchain features, where with fair exchange we mean the possibility for two users to swap digital goods such that neither can cheat the other through Zero Knowledge Contingent Payments (ZKCP) protocol.

Dec 10, 2019: Dario Fiore, Anaïs Querol and Matteo Campanelli have developed LegoSNARK, an efficient and modular framework to certify private data with minimal disclosure

Research results

Dario Fiore, Anaïs Querol and Matteo Campanelli, researchers of the IMDEA Software Institute, have talked about the new framework they have developed, called LegoSNARK, which paper was published at the ACM Conference on Computer and Communications Security.

Dario Fiore, Associate Research Professor, started saying that "in our society we often experience a tension between the privacy of our data and the utility of its use. For example, assume that you want to rent a house and the landlord ask you to prove that your monthly income exceeds the rental fee. Now, you would not like to reveal exactly how much you earn because for example this may induce the landlord to increase the price in the future. So, how can you then make this proof and without revealing too much information. Zero-knowledge proofs are a magical cryptographic tool that allows to prove a statement about private data without revealing more information than the fact that the statement is true".

The PhD student, Anaïs Querol started showing a physical example of how it is possible to convince the landlord that you can afford the rent. "Suppose that the rent costs 4 coins and we earn 10 coins. We insert those 10 coins inside this opaque coin dispenser, so by the shape of the dispenser at least you can see that I have 3 coins. How can I prove the landlord that I have at least 1 more? It is very simple, I simply get this one out and now you can see that I have 1,2,3 and 4. So the landlord knows that I can afford the apartment, but they have no clue about our spare money". She ends up saying that this can look quite simple, but in a digital transaction when you have to convince someone on the other side of the world cool mathematical techniques come into play to make it possible!

Matteo Campanelli, post-doctoral researcher, adds that now the emerging technologies like blockchains or cryptocurrencies are pressing out to make all these systems practical. "Recently at IMDEA what we did was tackling two of the main challenges in the space. The two main challenges are one, that these things, the digital analogy of the physical world opaque coin dispensers are very complex and the other is that they are slow. In order to tackle these problems, we develop a framework called LegoSNARK. Basically, we design techniques that allow to construct these systems not in a monolithic way but more modularly. So, think of not a whole piece of clay, but made of different construction blocks of sort, and that’s why we called it LegoSNARK. The interesting thing is that this approach also gives you more efficient zero-knowledge proofs in general".

Dec 4, 2019: Pedro Valero: On Facebook I have been studying the applications of grammar-based compression algorithms within industry

Scientific results

The pre-doctoral researcher of the IMDEA Software Institute, Pedro Valero, explains the work he has done recently that has taken him to Facebook.

"Technological giants generate vast amounts of information constantly and the only way they have to manage this information efficiently is by compressing it. However, they keep this information because they want to process it later, so saving the information in compressed form means that every time they want to query the information it is necessary to decompress it and perform the search on the original data. We specifically have been working with textual data. In this scenario, when compressing the file you need to find parts of the text that are repeated several times. Then the repeated text is written the first time it occurs and, for the rest of the occurrences, we simply indicate that what comes next is the fragment that appeared previously. This idea allows us to compress the file and save space but it also allows us to speed up the searches because, when we are processing the text, each time we find that what comes next has already occurred before, we can reuse the information we had already obtained when processing that same string of text. This idea is conceptually simple, but we have been among the first ones to put it into practice. We have developed an algorithm that allows us to perform these searches and really saves time.

If the file can be well compressed then the search in the compressed text without decompression can be faster than the whole process of decompressing and searching.

The problem with this approach is that not every compression algorithm works. Only a certain set of algorithms that are known as dictionary algorithms, or grammar-based, are worthwhile, and those algorithms are typically not studied within industry since they are generally slightly slower and more expensive, although they can produce good results.

The work that I have been doing with Facebook is to study this type of algorithms and find out in what context they can be used since, as usual, it is not always convenient to use them, but there are some scenarios in which it is worth to spend a little more time to compress the file in exchange for being able to search faster".

Dec 4, 2019: The directors of the seven IMDEA Institutes meet at IMDEA Energy to receive the Vice-President of the Community of Madrid and the Regional Minister of Science, Universities and Innovation

The vice-president of the Community of Madrid, Ignacio Aguado, the Regional Minister of Science, Universities and Innovation, Eduardo Sicilia, and the General Director of Research and Technological Innovation visit the IMDEA Energy Institute to learn about various initiatives against climate change. The political representatives have been received by the directors of the seven IMDEA Institutes.

During the tour through several laboratories, researchers of IMDEA Energy explained several projects in which they participate and, among other things, they highlighted that they have managed to produce kerosene from CO2, water and concentrated solar energy, which constitutes a worldwide milestone that could have important consequences both for long-distance aviation and for the naval sector.

In his speech to the media, Ignacio Aguado stated that "investing in scientific innovation and cutting-edge research programmes is a priority for this Government", which allocates 1.71% of its GDP to R&D activities.

The IMDEA Software Institute also contributes to the climate cause. Computer systems, from data processing centres to personal mobile devices such as smartphones, are major energy consumers. Reducing this consumption without cutting performance is a major challenge with a clear positive impact on the environment. Traditionally, there have been attempts to improve hardware, and currently, the focus is on improving software to perform the same functions with lower energy consumption.

Dec 2, 2019: Manuel Bravo designs algorithms for transaction processing in FARM-like databases to increase confidence in the correctness

Manuel Bravo, Post-doctoral Researcher at the IMDEA Software Institute has proposed elegant algorithms for transaction processing in FARM-like databases, proved their correctness and identified how they should be changed to exploit Remote Direct Memory Access (RDMA), a new networking technology that has the potential to drastically increase the scalability of distributed databases. However, to realize this potential, the algorithms for transaction processing in such databases have to be radically redesigned.

The first industrial database to use RDMA is the recent FARM system from Microsoft, which is now used to compute some of the search queries in Microsoft Bing. Unfortunately, the theoretical foundations of FARM have been shaky: its algorithms have not been proven correct and the rationale many of its design decisions was unclear.

Bravo, that has presented this proposal as a paper to PODC, demonstrates that the methodology for modifying transaction processing algorithms to run over RDMA also opens the door to exploiting RDMA for scaling up other industrial databases. This work has increased confidence in the correctness of FARM design, and allowed proposing its simplifications,

Nov 14, 2019: Researchers from the IMDEA Software Institute, Microsoft Research, and Saarland University have created Spectector, a tool that detects speculative leaks

Speculative execution attacks, such as Spectre, exploit critical vulnerabilities in modern processors to leak sensitive information. Marco Guarnieri, José F. Morales and Andrés Sánchez, from the IMDEA Software Institute, Boris Köpf, from Microsoft Research, and Jan Reineke, from Saarland University, have created Spectector, a tool for proving programs secure against such attacks. The research has been supported by a grant from the Intel Strategic Research Alliance.

Spectector implements the first principled approach for reasoning about the information leaks exploited by Spectre-style attacks. Spectector leverages symbolic execution and self-composition to automatically prove that programs satisfy a property called speculative non-interference, which guarantees the absence of speculative leaks, or detect violations.

Using Spectector, they detected subtle bugs in the way Spectre-countermeasures are placed by several major compilers, which may result in insecure programs or unnecessary countermeasures.

One of the evidences of the tool’s success is that this month the paper has been accepted at the IEEE Symposium on Security and Privacy 2020.

Nov 11, 2019: The activity of the Science and Innovation Week, The Roots of Software, welcomes more than 150 high school students

More than 150 high school students attended the activity "The Roots of Software", on the occasion of the Science and Innovation Week, an initiative from the Comunidad de Madrid, coordinated by the Knowledge Foundation Madri+d, aimed at introducing young talents to software research through challenges, games and videos. A different way of disseminating the science of the IMDEA Software Institute, promoting STEM vocations and attracting future promises.

The director of the Institute, Manuel Carro, was in charge of opening the event and welcoming the students. After him, a promotional video was presented. It tells in a direct and impressive way, the work that is done in software research.

Once the video broadcast was over, the pre-doctoral researchers Silvia Sebastián and Pedro Valero, began to tell what they do and quickly moved on to the games that entertained young people for more than two hours.

They taught the students how problems can be solved faster thanks to parallelization, with sums of large numbers in parallel. Several volunteers were invited to go out on the whiteboard and try to solve the equation in the shortest possible time. In addition, they explained that when working in parallel, it is necessary to coordinate the processes (concurrence). In this sense, the students successfully tried to solve the problem of the philosophers' dinner.

Cryptography was also present, Silvia and Pedro hid a report and the attendees had to break the encryption to know its location.

Another themes of the games were formal systems, the turing test to differentiate humans from machines and finally they used the Kahoot tool so that the young people could vote if the people from the images and videos that were shown to them were fruit of an artificial intelligence or human.

Oct 1, 2019: The IMDEA Software Institute and EIT Digital organize the first hackathon in Spain on the use of blockchain for environmental action

Blockchain is not a fad, it is a promising technology that has wide applicability. Sustainability is not only a noun; protecting our planet has become a moral obligation. This is why chainrEaction has been created. It is the first hackathon organized by the IMDEA Software Institute y EIT Digital on the use of blockchain technology to develop sustainable solutions for the communities of the future and thus slow down climate change.

ChainrEaction has two main objectives: bring students closer to research and innovation in the area of blockchain; and contribute to the creation of novel solutions for a more sustainable future.

The event will take place from the 3rd to 5th of February 2020 in Madrid, Spain. A maximum of 33 students can attend and to make sure that you can get here, we will provide travel grants. You will enjoy a unique learning and hacking experience, with a program composed of research and industry talks, technical tutorials and ample time for hacking in groups of 3. You will be guided by top researchers from the IMDEA Software Institute and other research institutions.

The key areas of chainrEaction are:

  1. Transforming urban communities. How can cities and citizens directly use blockchain to reduce pollution, carbon emissions, etc. and to incentivize greener living?
  2. Greener infrastructures and preservation of natural resources. How can blockchains incentivize greener business practices or improve oversight by regulatory agencies?

We accept applications from students in Computer Science and related fields, at the BSc, MSc and PhD level. We will select the all-round strongest candidates – blockchain experience is not a must! Applications until the 17th of November 2019 (23:59 UTC) through: https://apply.chainreaction.es/.

Sep 30, 2019: IMDEA Software participates in the 3rd season of IMDEA-CSI in the European Researchers Night

The third season of the IMDEA-CSI activity took place last Friday, the 27th of September, on the occasion of the European Researchers' Night coordinated by the Knowledge Foundation, Madri+d.

The IMDEA Software Institute participated one more year, in this occasion, with the representation of the director of the Institute, Manuel Carro and the postdoctoral researcher Matteo Campanelli.

Carro welcomed the nearly 200 young people who attended. He introduced the crime simulation format that was going to be recreated and assured that "today there are no actors, the researchers that you will see are part of the staff of all the IMDEA Institutes and the members of the Police are not only part of the General Direction of the Scientific Police, but everything they will do at the crime scene is the same as they would do in real life". Finally, the director of the Institute ended by making the room aware that science is behind almost everything.

In this occasion the action takes place in a research center. One of its members appears dead in his office and from there the Scientific Police, as well as researchers come into action to collect and analyze evidence from the crime scene.

The researcher Matteo Campanelli talked about privacy during his presentation and how some tools that are sold as secure offer sensitive user information with which many things can be deduced, such as a person's identity. In this sense, he analyzed the Tablet of the corpse and finds an anonymized clinical database that along with other public data on the web, reveals that he had information about the pregnancy of a partner. From which it can be deduced that the victim was blackmailing her.

Once again, in the end thanks to the joint collaboration between investigators and the National Police, the victim was found guilty of the crime.

Sep 2, 2019: IMDEA Software, through REDIMadrid, will participate in the EU Project OPENQKD

Today marks the launch of a pilot project, OPENQKD, that will install a test quantum communication infrastructure in several European countries. The IMDEA Software Institute will participate in the recently funded EU project OPENQKD by providing physical infrastructure and the expertise of personnel of the REDIMadrid innitiative, managed by the Institute. The whole consortium is composed by 38 members, 4 of them from Spain.

Classical and quantum communications will jointly ensure the ICT needs of European governments, service industries (e.g. health, finance), businesses and citizens, even in the presence of quantum computers, or other sophisticated algorithmic attacks against public key infrastructures.

The Project mission is the establishment of QKD-based secure communication as a well-accepted, robust and reliable technology instrumental for securing traditional industries and vertical application sectors, and to prepare the deployment of Europe-wide QKD-based infrastructure in future.

The high level objetives are: raising the awareness of the maturity of QKD; working with end-users to test and validate end-to-end security for businesses and industry sectors based on QKD; advancing QKD systems and QKD-based secure-communication solutions to meet market demands in terms of specifications, standards & certification; and finaly, provide several open test facilities to encourage the development of new QKD-based applications by a wide community.

REDIMadrid is deploying a research network over its own infrastructure. The aim is to avoid a hired capacity network, with new dark-fiber laid out and used exclusively for research activities.

In this context, REDIMadrid will facilitate that quantum lambdas can coexist with lambdas of research traffic, so, it will be possible to verify how the solution works in a real environment.

To achieve its ambitious goals, the OPENQKD project will last three years and have a budget of €15 million funded under H2020-EU.2.1.1. This project has received funding from the European Union´s Horizon 2020 research and innovation programme under the grant agreement no. 857156.

Jul 15, 2019: The Madrid Regional Ministry of Education and Research visits SENER to get to know the 'Madrid Flight on Chip' project

The aerospace division of the engineering and technology group (SENER) has received today the Madrid Regional Minister of Education and Research, Mr. Rafael van Grieken, and the General Director of Research and Innovation, Mr. Alejandro Arranz, to present the company activities in the aerospace sector, especially the 'Madrid Flight on Chip' project, partially funded by the Madrid Regional Government and the European Regional Development Fund.

The General Manager of SENER Aerospace, Mr. José Julián Echevarría, and the Business Development and Strategy Manager of SENER Aerospace, Mr. Diego Rodríguez, welcomed the attendees, gave an initial presentation of the work being carried out at SENER, and briefly explained the 'Madrid Flight on Chip' (MFoC) project. Afterwards, there was a tour showcasing some of the main projects and capabilities of SENER in the aerospace sector.

The visit ended with a more in-depth presentation of the MFoC project by the representatives of the partners: SENER (project coordinator), the Carlos III University of Madrid (uc3m), the IMDEA Software Institute, The Reuse Company, Centum Solutions, Genera Tecnologías, and MARM.

The scientific director of IMDEA Software, Manuel Carro, said: "software is playing a predominant role in aerospace technology today. Moving from embedded, intercommunicating, and certified systems to having system-on-chip makes developing their software much more challenging than before". In addition, Carro has declared how important it is for the IMDEA Software Institute to participate in a project of this caliber: "we are very happy to collaborate in MFoC because it gives us exposure to a type of software - -aerospace software- to which we do not normally have access. By its characteristics, we believe it is a class of complex software that performs essential functions and that we see a an opportunity to apply and evolve our capabilities, while still posing an affordable challenge".

Rafael van Grieken, Regional Minister of Education and Research, stated that Madrid is a focus of attraction for companies today but that there is still a need to strengthen business initiatives, particularly based on advanced technologies. "I am convinced that the Madrid Flight On Chip project will impact more satellites, more companies, and many more people on planet Earth than those of us who are here in Madrid and in Spain", concluded Mr. van Grieken.

Jun 11, 2019: The Demo by Lucas Kuhring and Zsolt István on "Bionic Distributed Storage for Parquet Files", accepted at VLDB'19

Lucas Kuhring and Zsolt István, researchers at the IMDEA Software Institute, will present a demo "I Can't Believe It's Not (Only) Software! Bionic Distributed Storage for Parquet Files" at the 45th International Conference on Very Large Data Bases (VLDB'19) in Los Angeles, USA.

The size of data to be stored and processed as part of data science applications is increasing and leading to bottlenecks and inefficiencies in the datacenter. A way to reduce these bottlenecks is by tailoring the underlying distributed storage solution to the application domain, using resources more efficiently. Lucas and Zsolt have explored this idea in the context of a popular column-oriented storage format used in big data workloads, namely Apache Parquet.

The prototype they have created uses a storage node based on Field Programmable Gate Arrays (FPGAs) that offers high bandwidth data deduplication and, in the future, near data processing for machine learning workloads. The hardware is combined with a software library that allows transparent access to Parquet files.

The demonstration shows that it is possible to implement in-line deduplication without increasing latencies significantly or reducing throughput by relying on the FPGA's dataflow processing model. It also highlights the benefits of implementing the application-specific aspects in a software library instead of FPGA circuits and how this enables, for instance, regular data science frameworks running in Python to access the data on the storage nodes.

Mar 18, 2019: Zsolt István awarded Marie Skłodowska-Curie Individual Fellowship for the ACCORD project

IMDEA Software IMDEA Software Institute Faculty Zsolt István was awarded a Marie Skłodowska-Curie Individual Fellowship, for the Project Accelerated Ordering Service for Distributed Ledgers (ACCORD). The project sets out to improve blockchain systems that target Business to Business use-cases and builds on earlier success in the use of specialized hardware to implement distributed algorithms.

Distributed ledgers (DLs), or blockchains, have the potential of transforming the ways individuals and businesses interact by reducing the cost of transactions and the associated delays dramatically. How can this be done? Delegating today’s trusted third party guarantee to a distributed computing network that relies on cryptographic operations and sophisticated distributed consensus algorithms to ensure that transactions are recorded durably and in a tamper-free manner.

The adoption of DLs outside of crypto-currency use cases has been slow for performance reasons. The ACCORD project aims to increase distributed ledger throughput by at least an order of magnitude, while lowering latencies by a similar factor. To achieve this, the focus is on the core component of DL systems, namely, distributed consensus that is used to establish an absolute order of transactions. This ordering operation is one of the main performance bottlenecks in DLs. So, to fully exploit emerging network technologies and to overcome stagnating CPU performance, ACCORD is planning to use hardware acceleration to offload the steps required by the ordering service.

In the end, the foreseen outcome of the ACCORD project is a DL design with performance that allows it to be deployed in use-cases in which DLs are inadequate today as, for example, trading.

This project has received funding from the European Union’s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie grant agreement No. 842956.

Jul 14, 2018: Four papers by IMDEA researchers presented at ICLP/FLoC 2018

IMDEA Software Institute researchers have presented several papers at the 34th International Conference on Logic Programming (ICLP'18), that this year was a part of the Federated Logic Conference (FLoC'18), held July 14-17, 2018, in Oxford, UK. FLoC is a major event celebrated once every four years which gathers all the major conferences related to logic and computer science. ICLP is the top international venue in the area of Logic Programming and is part of FLoC.

IMDEA Software Institute director Manuel Carro was a member of the Program Committee of ICLP this year. PhD student Joaquin Arias presented s(CASP), a system developed in collaboration with Manuel Carro and researchers from the University of Texas at Dallas. s(CASP) evaluates non-monotonic programs with constraints avoiding the combinatorial explosion due to the grounding phase. The paper entitled "Constraint Answer Set Programming without Grounding", to be published in Theory and Practice of Logic Programming, describes this novel execution model and shows through several examples the enhanced expressiveness of s(CASP) w.r.t. ASP, CLP, and other CASP systems.

PhD student Maximiliano Klemen presented a technical communication on his work with recent PhD graduate Nataliia Stulova, and IMDEA Software faculty members Jose F. Morales, Pedro Lopez-Garcia, and Manuel Hermenegildo, entitled "Towards Static Performance Guarantees for Programs with Run-time Checks". This work presents a framework for reasoning statically about the overhead added to programs by run-time checks in terms of both algorithmic complexity and actual cost changes. Moreover, the framework allows programmers to specify an "admissible" overhead level per program routine (function, predicate, etc.), and automatically and statically check whether the program with run-time checks adheres to such specification for all possible executions.

PhD student Isabel Garcia presented a technical communication on her work with IMDEA Software faculty members Jose F. Morales and Manuel Hermenegildo, entitled "Towards Incremental and Modular Context-sensitive Analysis". This work tackles the issue of the high cost of context-sensitive static analysis on large code bases during the development process. The authors present an approach that combines fine-grain incrementality and modularity, which was not covered by previous approaches. Analysis results are updated at the particular places where the changes to the code are introduced (incrementality), which is significantly less costly than performing global system-level analysis. Local updates are propagated as necessary to the affected program units (modularity), obtaining the same results as standard modular global analysis with greatly reduced cost.

Faculty member Pedro Lopez-Garcia presented his work with PhD student Maximiliano Klemen, recent PhD graduate Umer Liqat, and faculty member Manuel Hermenegildo, entitled "A General Equational Framework for Static Profiling of Parametric Resource Usage" at the 19th Workshop on Logic and Computational Complexity (LCC'18). This novel framework for setting up cost relations can be instantiated for performing a wide range of resource usage analyses, including both static profiling of accumulated cost and the inference of standard notions of cost. This allows identifying statically the parts of programs that have the greatest impact on the total cost.

Jul 10, 2017: Juan Caballero's team receives the Most Influential Paper Award at DIMVA

IMDEA Software Institute researcher Juan Caballero, graduated Ph.D. student Antonio Nappa, and former intern M. Zubair Rafique have received the Most Influential DIMVA paper 2009-2013 Award for their paper "Driving in the Cloud: An Analysis of Drive-by Download Operations and Abuse Reporting". The award recognizes the most influential paper published in a period of 5 years at DIMVA, the International Conference on Detection of Intrusions and Malware & Vulnerability Assessment. The authors received their award at the gala dinner of DIMVA 2017, which was held on July 6-7 2017 in Bonn, Germany.

The winning paper was published in DIMVA 2013. It proposed a technique to identify exploit servers managed by the same organization. Exploit servers are Web servers that try to exploit vulnerabilities in the browser and browser plugins (e.g., PDF or Flash players) of visitors. If exploitation is successful, malware is installed on the visitor's computer. This process is known as a drive-by download. In the drive-by ecosystem many exploit servers run the same exploit kit software and it is a challenge understanding whether the exploit server is part of a larger operation. The paper results revealed that although individual exploit servers have a short median lifetime of a few hours, attackers were able to sustain long-lived malware distribution by turning to the cloud, hosting their exploit servers in specialized cloud hosting services.

As a result of the paper the authors released the Malicia dataset, which comprised 11688 malware binaries collected from 500 drive-by download servers over a period of 11 months, a database that details when and from where the malware was collected, and the malware classification into families. The dataset enables, among other applications, evaluating malware clustering and labeling approaches. Since its release, the Malicia dataset has been requested by 73 research institutions worlwide.

Jun 20, 2017: Pedro López-García and Manuel Hermenegildo recipients of Test of Time award at top conference

IMDEA Software Institute faculty members Pedro López-García and Manuel Hermenegildo are, with co-authors Jorge Navas (SRI) and Edison Mera (PDC), the recipients of the 10 year Test of Time Award at the 33rd International Conference on Logic Programming (ICLP 2017), the premier conference in the area, for their paper "User-Definable Resource Bounds Analysis for Logic Programs", published in ICLP 2007. The 10 year Test of Time Award recognizes the paper published 10 years ago which has had the largest impact.

The winning paper by Navas, Mera, López-García, and Hermenegildo proposed and developed a technique that allows programmers to implement analysis and verification tools for a very wide class of resources (including execution time, energy consumption, and other user-defined quantitative properties) in a straightforward way, by just defining these resources and other parameters through simple program annotations. The program together with these annotations and resource specifications constitute the input to a customizable analyzer (implemented within the CiaoPP tool) which automatically, and without running the program, predicts the usage of the resources defined in order to guarantee that the program's resource usage will be within the specified limits.

Since its proposal in 2007 the approach and its implementation in CiaoPP have been applied by different groups for computing upper and lower bound functions on resources such as memory consumption, execution time, or energy, for a wide variety of programming languages, ranging from high-level source to bytecode and to machine code. It has also been improved, extended, and generalized in several ways over the last 10 years.

Faculty member Juan Caballero and Ph.D.student Platon Kotzias Platon Kotzias have a paper at the 36th IEEE Symposium on Security and Privacy, a top-ranked conference held in San Jose, CA. The paper was in collaboration with Chaz Lever and Manos Antonakakis from Georgia Institute of Technology and Davide Balzarotti from Eurecom, France. The work, that can be found here, performs a large-scale analysis of malware network communication using 26.8 million malware samples in combination with over 5 billion DNS queries collected from a large North American internet service provider (ISP). Among other, they discover that domains contacted from malware are observed in ISP network traffic often weeks or months before the malware shows up in the malware feeds. They also show that potentially unwanted programs (PUPs) rely on a surprisingly stable DNS and IP infrastructure.

The paper has been recently presented at the 40th M3AAWG General Meeting in Lisbon on June 15th.

Dec 16, 2016: A new prestigious ERC Grant awarded to an IMDEA Software researcher

IMDEA Software Institute faculty member Aleks Nanevski receives a prestigious ERC Consolidator Grant for the project "Mathador - Type and Proof Structures for Concurrent Software Verification".

Concurrent programs are notoriously difficult to write because of the complexity of interaction between their components. This complexity comes into the sharpest focus if one tries to develop a mathematical, computer-checkable, proof that a concurrent program produces the desired result. The required effort for developing such a proof today is overwhelming even for the simplest concurrent programs, because of the combinatorial explosion associated with the component interaction.

The goal of the Mathador project is to study, decompose, and simplify the structure of mathematical proofs of concurrent programs, to the point where they can be developed on a regular basis. Mastering these proofs will mean that we know how to describe the interaction between concurrent components in an intellectually manageable way. In turn, this will directly impact how we think about, write, and understand concurrent software.

Sep 10, 2015: IMDEA Software Institute PhD student Alejandro Sánchez graduates

The thesis studies the formal verification of temporal properties of safety and liveness of parametrized concurrent systems, with a special focus on programs that manipulate complex concurrent data structures in the heap. This work presents a formal framework based on deductive methods which cleanly separates the analysis of the program control flow from the data manipulated by the program. The program control flow is analyzed using novel specialized deductive verification techniques specifically designed for coping with parametrized systems. Starting from a concurrent program and a temporal specification, the techniques generate a finite collection of verification conditions whose validity entails the satisfaction of the temporal specification by any client system, in spite of the number of threads. Additionally, the thesis explores the construction of decidable theories equipped with decision procedures that can automatically check the generated verification conditions for some complex concurrent data structures. Finally, the whole framework is evaluated over some safety and liveness properties for a collection of mutual exclusion protocols and concurrent pointer-based data structures.

Alejandro Sánchez was advised by IMDEA Software Institute faculty member César Sánchez and obtained his degree from Universidad Politécnica de Madrid with a "cum laude" mention.

May 5, 2015: COST Action “Runtime Verification Beyond Monitoring (ARVI)” Begins

The first scientific meeting of the EU COST Action "Runtime Verification beyond Monitoring (ARVI)" has taken place in Valletta, Malta on April 9th and 10th. IMDEA Software Institute faculty member César Sánchez is a member of the management committee and a workgroup leader, and a leader in the COST Action proposal’s elaboration.

Runtime verification (RV) is a computing analysis paradigm based on observing a system at runtime to check its expected behavior. RV has emerged in recent years as a practical application of formal verification, and a less ad-hoc approach to conventional testing by building monitors from formal specifications.

The main goals of the action are:

  1. to create an infrastructure that supports comparing tools and reusing existing infrastructure in runtime verification,

  2. to explore potential impactful applications of runtime verification to industrial settings like hardware, medical devices, cloud computing, and even human centric systems, and

  3. to explore challenging application domains for monitoring and runtime verification, such as hybrid systems and distributed systems.

Given the importance of computer-based industries in Europe, novel applications of RV have a large impact in terms of the new class of designs enabled and their reliability and cost effectiveness.

This COST Action is funded for 4 years, until 2018.

Apr 23, 2015: IMDEA Software Institute PhD student Miguel Ángel García de Dios graduates

The thesis presents a novel, tool-supported model-driven methodology for developing secure data-management applications. With the methodology defined, developers proceed by modeling three different views of the desired application: its data model, security model, and GUI model. These models formalize respectively the application's data domain, authorization policy, and its graphical interface together with its behavior. Afterwards a model-transformation function automatically lifts the policy specified by the security model to the GUI model. Finally, a code generator automatically generates a multi-tier application, along with all support for access control, from the security-aware GUI model. Miguel Ángel García de Dios was advised by IMDEA Software Institute faculty member Manuel Clavel and obtained his degree from Universidad Complutense de Madrid.

Mar 4, 2015: TLS Encryption-Breaking FREAK Exploit Discovered

IMDEA Software Institute faculty researcher Pierre Yves Strub, together with his colleagues at INRIA Rocquencourt, France and Microsoft Research have uncovered a vulnerability in the popular SSL encryption mechanism used widely on the Internet to access web pages securely. The flaw, dubbed “FREAK: Factoring RSA Export Keys” can be exploited to trick web browsers into interacting with malicious websites. The problem affects a large number of web servers and clients and has thus received major media impact.

This discovery was made within the ongoing SMACK TLS project, which is aimed at developing increasingly-secure Internet authentication software. Pierre Yves Strub and his colleagues have developed an automated technique to discover vulnerabilities in implementations of authentication protocols, and uncovered several vulnerabilities which, gone unnoticed, could be exploited by hackers to compromise Internet security.

The researchers focused on the family of authentication protocols know as “Transport Layer Security” (TLS), which is the increasingly-popular successor to the ubiquitous “Secure Sockets Layer” (SSL) protocol family. By building formally-verified reference implementations of TLS protocols, they were able to systematically generate inadmissible protocol responses, which should be disallowed by the protocol, and test whether any of those responses were in fact admitted by existing implementations. Inadmissible responses suggest potential vulnerabilities, and were to converted into exploits in actual TLS implementations. “FREAK” is one of the vulnerabilities discovered.

This work was performed in collaboration with Benjamin Beurdouche, Karthikeyan Bhargavan, Antoine Delignat-Lavaud, Alfredo Pironti, and Jean Karim Zinzindohoue of INRIA Rocquencourt, France, and Cedric Fournet and Markulf Kohleiss of Microsoft Research.

Dec 23, 2014: IMDEA Software Verifier Wins Gold Medals in International Competition

The International Competition on Software Verification (SV-COMP) is a driving force for the invention of new methods, technologies, and tools for the automated verification of computer software. Software verification is an unarguably-important research area as society becomes more and more dependent on its correct functionality: software bugs can cost lives and great monetary loss. Though the goal of verified software has existed since the dawn of computer science, the technology enabling widespread use of software verifiers has been extremely challenging to develop, due to fundamental philosophical limitations, practical engineering obstacles, and the challenge in surmounting both simultaneously. SV-COMP aims to advance software verification technology by bringing together the top international minds.

This year marks the 4th annual installment of an increasingly-competitive event, in which 22 entries from top research institutions including New York University, Ecole Normale Supérieure (ENS) of Paris, University of Freiburg, Tsinghua University, Microsoft Research, and IMDEA Software Institute compete across 13 categories of software verification problems.

Each competition entry is a computer program called a “verifier”, and each “problem” is a computer program whose correctness must be verified by the verifier. The verifiers are submitted as executable code, and the problems are provided as source code written in the C programming language. The verifiers classify problems either as “correct”, “incorrect”, or “unknown”, within a time limit of 900 seconds per problem. Points are awarded according to the accuracy of classification. In each problem category, the three highest-scoring verifiers are awarded medals: gold, silver, and bronze.

In collaboration with the University of Utah and Microsoft Research, the IMDEA Software Institute’s competition entry, named SMACK+Corral, was awarded medals in four categories — two gold, one silver, and one bronze — placing it among the top-performing verifiers. Only one entry earned more gold medals, and only three entries earned more medals total.

Technically, SMACK+Corral is the fusion of two programs. SMACK is an open-source project led by Zvonimir Rakamaric of the University of Utah, and Michael Emmi of the IMDEA Software Institute. The role of SMACK is to translate the C-language verification problems into mathematical representations which can be more-easily processed by automated logical-reasoning engines known as “theorem provers”. Corral, developed by Microsoft Research, applies novel reasoning algorithms to decide whether the given mathematical representation should be classified as “correct”. Combined, the two function as a powerful verifier of C-language programs.

The SV-COMP 2015 post-competition event is being held on the week of April 13th, 2015, as part of the 21st International Conference on Tools and Algorithms for the Construction and Analysis of Systems (TACAS), in London, UK. The event includes a short presentation by the authors of each entry, and an official announcement of the competition results.

December 8, 2011: Dragan Ivanović, Manuel Carro and Manuel Hermenegildo win Best Paper Award at ICSOC 2011

The paper Constraint-Based Runtime Prediction of SLA Violations in Service Orchestrations, co-authored by IMDEA Software Institute and UPM Researchers Dragan Ivanovic, Manuel Carro, and Manuel Hermenegildo, was selected as the Best Paper Award at ICSOC 2011, the 9th International Conference on Service Computing held at the Paphos, Cyprus, Dec 5–8, 2011.

The paper presents and evaluates a technique to detect ahead of time whether there will be or not SLA violations in service orchestrations, and to determine under which conditions these will (or will not) happen. The technique uses a model of the process which can evolve as the process executes, thus making it possible to reflect dynamic changes. At every inspection point, the continuation of the process model is sent to the predictor which produces a constraint model by means of symbolic execution using a constraint-generating interpreter. The constraint system is fed into a Prolog-based constraint solver which is, additionally, given boundary conditions to represent scenarios of failure and non-failure. The results of the constraint solver indicate the cases under which these scenarios will or may occur. Evaluations under realistic conditions obtained using the Microsoft Workflow Engine indicate significant prediction capacity with very small numbers of false positives / negatives.

August 15, 2011: Gilles Barthe and Santiago Zanella win Best Paper Award at CRYPTO 2011
