Operational models of (security) protocols, on the one hand, are readable and conveniently match their implementations (at a certain abstraction level). Epistemic models,on the other hand, are appropriate for specifying knowledge-related properties such as anonymity or secrecy. We propose a unified framework for formal specification and verification of both epistemic and behavioral aspects of security protocols. The framework provides explicit support for cryptographic constructs, which are among the most essential ingredients of security protocols. The main practical motivation for this work came from the domain of e-voting protocols. Hence, we investigate the applicability of the framework...
