Abstract:
Privacy and security are two important issues in vehicular networks. Traditional authentication methodologies such as public/private keys & their corresponding certificates are not feasible to protect location privacy and security due to large computing overhead. In this paper, we propose an Efficient Privacy Preservation (EPP) protocol in vehicular ad-hoc networks, which, uses smart card functionality to authenticate users and employs bilinear pairings method to generate the public and private key. The public key is derived from the signature of the user’s pseudonym identity and private key signed by a trust authority and roadside units, hence, users can verify signatures without their corresponding certificates. Performance analysis shows the proposed EPP protocol can authenticate vehicular users and data messages with low time complexity and preserve users’ privacy.
