A State Space Suppression Method for Formal Verification of Secure Routing Protocols With SPIN

Abstract

ISDSR has been recently introduced as a secure routing protocol of wireless multi-hop networks to guarantee the reliability of routes between nodes by using single signatures from any source to its destination. In this paper, we propose a method for formal verification of ISDSR with SPIN. The proposed method is based on symmetry reduction to mitigate the state space explosion. We also implement the proposed method and conduct preliminary experiments with the original DSR. As a promising result, the proposed method is able to suppress state space and memory usage. However, we also found some technical problem via experiments with ISDSR. Hence, we further discuss improving the proposed method.
