A Generic Model for Analyzing Security Protocols

Abstract

Formal methods have proved useful in the analysis of security protocols. The paper proposes a generic model for the analysis of the security protocols (GSPM for short) that supports message passing semantics and constructs for modelling the behavior of agents. GSPM is simple, but it is expressive enough to express security protocols and properties in a precise and faithful manner. Using GSPM it is shown how security properties such as confidentiality, authentication, non-repudiation, fairness, and anonymity can be described. Finally an example of formal verification is illustrated.
