WebCryptoVerif 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. WebJan 3, 2024 · We then perform symbolic execution of that path to extract a model expressed in a process calculus similar to the one used by the CryptoVerif tool. The symbolic execution uses a novel algorithm that allows symbolic variables to represent bitstrings of potentially unknown length to model incoming protocol messages.
