Reasoning About Recognizability in Security Protocol Analysis

Although verifying a message has long been recognized as an important concept in security protocol analysis, there is no consensus on its exact meaning. Such a lack of formal treatment of the concept makes it extremely difficult to evaluate the vulnerability of security protocols. This talk addresses the question: what is meant by saying that a message can be verified? The core technical innovation is a third notion of knowledge in security protocols -- recognizability. It can be considered as intermediate between deduction and static equivalence, two classical knowledge notions in security protocols. I will then give several examples to show how recognizability shed important lights on the study of security protocols.
