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.
