Dear students,

Please find attached the homework for the cryptography module of the Computer Security course. Sorry for the slight delay with respect to what I had said on Monday.

Here are some instructions: - You have to return it no later than October 27. - Please return the solution by email to both Dario and Ignacio (ignacio.cascudo@imdea.org , dario.fiore@imdea.org ). - You can return the solution either handwritten or typeset (appreciated). You can even edit directly the latex file attached. - The homework must be done individually. Any spotted collaboration will result in the annulment of the homework.

In case you have some questions about the homework you can send us an email (ignacio.cascudo@imdea.org , dario.fiore@imdea.org)

Best regards, Ignacio and Dario
