Symbolic semantics and analysis for Crypto-CCS with (almost) generic inference systems

Crypto-CCS is a formal description language for distributed protocols which is suitable to abstractly model the cryptographic ones. Indeed, this language adopts a message-manipulating rule which may be used to mimic some features of cryptographic functions. We equip the Crypto-CCS calculus with a symbolic operational semantics. Moreover, we provide a mechanized method to analyze the security properties of cryptographic protocols (with finite behaviour), symbolically. Our work extends the previous one on symbolic verification techniques for cryptographic protocols modeled with process algebras since it deals with (almost) generic inference systems instead of fixed ones.
