CASCADE

Cryptography, or the "Science of Secret", aims at protecting digital data during communications, or while they are locally stored. On this security track, two activities fight: the design of systems achieving the security goal, and the attack that tries to defeat security protections. The CASCADE project-team studies a very large range of cryptography: design of primitives and protocols, together with the security analysis, which can turn out to provide attacks at various levels: on the mathematics or algorithmic, on the actual implementation, or exploiting side-channel informations for the hardware.
