Model-based verification of privacy preserving authentication protocol for VANETs

摘要

The paper presents the verification of a privacy preserving authentication protocol using a finite state model checker SPIN. Authentication of various entities, vehicles and road side units, is vital for accepting the authenticity of messages broadcast by them. These messages are critical and actions taken by vehicles are related to human life. The authentication protocol is a distributed and asynchronous in nature. In the present work, the correctness of the protocol is verified using SPIN and its structure is depicted using finite state and sequence diagram. The results indicate that the proposed protocol is correct and meet the requirements of VANET.
