CryptoVerif

CryptoVerif^[1] is a software tool for the automatic reasoning about security protocols written by Bruno Blanchet. Contrary to ProVerif by the same creator that uses a symbolic abstraction, it is sound in the computational model.

It can prove secrecy and correspondences properties. The latter include in particular authentication.

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 can 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).
