We present a framework for modeling adversaries in security protocol analysis, ranging from a Dolev-Yao style adversary to more powerful adversaries who can reveal different parts of principals’ states during protocol execution. Our adversary models unify and generalize many existing security notions from both the computational and symbolic settings. We extend an existing symbolic protocol-verification tool with our adversary models, resulting in the first tool that systematically supports notions such as weak perfect forward secrecy, key compromise impersonation, and adversaries capable of state-reveal queries. In case studies, we automatically find new attacks and rediscover known attacks that previously required detailed manual analysis.
