The Formal Verification and Improvement of Simplified SET Protocol
Meihua Xiao, Zilong Wan, Hongling Liu · Journal of Software · 2014
Abstract—Model checking has been successfully applied to verify the security properties of network protocols. In this paper, we propose a formal modeling method using the PROMELA language based on simplified model of SET payment protocol proposed by Lu & Smolka, and use LTL to describe authentication property. Under the hypothesis of the network environment being controlled by the intruder, we use SPIN to find the attacks and improve the verification efficiency by using the optimization strategies of atomic steps and Bit-state hashing technology. Finally, we improve the existing vulnerabilities of the SET protocol.
