Publication Abstract

This paper introduces an authentication protocol for vehicular communications, which uses two techniques to preserve privacy namely pseudonym and group signcryption. The main features of this protocol: Firstly, it offers conditional anonymous authentication: a message sender is authenticated anonymously on behalf of a group of potential signers while only a trusted entity (group manager) can reveal the real identity of a message issuer. Secondly, it guarantees message integrity and prevents replay attacks. Thirdly, it is efficient in terms of storage requirements in vehicle, message verification cost and tracing complexity in case of dispute.
