  Abstract

Various studies have been conducted for VANET (Vehicular adhoc network) security and privacy. There are still many issues to be solved in the previous researches, such as the overhead of communication and computation, and security and privacy issues. In this paper, we withdraw two weaknesses in Ying and Nayak’s authentication protocol over VANET, which are weaknesses focused on the denial of service attack and the anonymity exposure attack. In addition, we propose a privacy preserving authentication protocol for VANET to solve the problems in Ying and Nayak’s authentication protocol. The proposed protocol provides a high level of privacy and security at the same time by removing the usage of verifier table in the trusted server. To validate mutual authentication, we use a formal validation tool ProVerif. In particular, the proposed protocol can resist attacks such as offline password guessing attacks, smart card loss attacks and impersonation attacks, and provide anonymity and unlinkability.
