Abstract
In this paper, protocol insecurity problem is described, and AI planning system is used to solve the problem. Based on running characteristics and laws of cryptographic protocols, a planning-based formal model for cryptographic protocol analysis is presented, after its first-order syntax, formal definition and operational semantics are given, formalization for protocol honest agents, the intruder and protocol insecurity goals are presented, and a SAT-based solving algorithm for attack planning is proposed.
