A BSP Algorithm for On-the-fly Checking LTL Formulas on Security Protocols

Abstract

This paper presents a Bulk-Synchronous Parallel (BSP) algorithm to compute on-the-fly whether a structured model of a security protocol satisfies a LTL formula. Using the structured nature of the security protocols allows us to design a simple and efficient parallelisation of an algorithm which constructs the state-space under consideration in a need-driven fashion. A prototype implementation has been developed, allowing to run benchmarks.
