CryptoVerif: Cryptographic protocol verifier in the computational model

Project implementer:

• secrecy;
• correspondences, which include in particular authentication.

The generated proofs are proofs by sequences of games, as used by cryptographers. These proofs are valid for a number of sessions polynomial in the security parameter, in the presence of an active adversary. CryptoVerif can also evaluate the probability of success of an attack against the protocol as a function of the probability of breaking each cryptographic primitive and of the number of sessions (exact security).

This prover is available below. This software is under development; please use it at your own risk. Comments and bug reports welcome.
