Verification of Privacy Preserving Authentication Protocol for VANETs

The paper presents verification of privacy preserving authentication protocol for VANETs using SPIN tool. The authentication process involves authentication of the moving vehicle and the corresponding road side unit (RSU) by a fixed infrastructure from (CTA) through RSU. The whole process needs only one request and reply between different entities. The work described the impact of known attack on the protocol, graphically specification, its behavior in terms of reliability and its correctly verification using the integrated specification verifying JSPIN tool.
