CryptoVerif is a software tool for the automatic reasoning about security protocols written by Bruno Blanchet. Supported cryptographic mechanisms It provides a mechanism for specifying the security assumptions on cryptographic primitives, which can handle in particular symmetric encryption, message authentication codes, public-key encryption, signatures, hash functions. Concrete security CryptoVerif claims to evaluate the probability of a successful attack against a protocol relative to the probability of breaking each cryptographic primitive, i.e. it can establish concrete security.
