Analyzing Cryptographic Protocols Using AI Planning Technology

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.
