摘要

Cryptographic protocol is the crucial secure mechanism for sharing network resources. The security of the cryptographic protocol plays a vital role to entire network environment. In this paper,a new Colored Petri Nets (CPN) methodology for security property analysis of cryptographic protocol is proposed. We apply the new approach to modeling the TMN protocol with multiple concurrent sessions,and the model is categorized based on session configuration and session schedule. Using the state space search method,several attack states of multiple concurrent sessions are found,and a new attack pattern is obtained.
