Conditional privacy-preserving authentication using registration list in vehicular ad hoc networks.

AbstractVehicular ad hoc networks (VANETs) have increased in popularity in recent years and play an extremely important role in the intelligent transportation field. However, the demands of larger communication networks and the integrated message verification process for ensuring security incur more communication and computation overheads, and directly affect the efficiency of existing VANET schemes. To address this issue, this paper proposes a novel and practical conditional privacy-preserving authentication (CPPA) scheme, which uses the registration list instead of the revocation list to reduce the communication overhead. Specifically, our scheme can prevent malicious vehicles from disrupting the security features of VANETs. Moreover, we do not use the bilinear pairing operation, which is the most complicated operation in modern cryptography, thus significantly reducing the computation overhead and communication overhead. Security and performance analyses demonstrate that our proposed scheme is more secure and efficient than current schemes, and that the proposed scheme is more suitable for VANET deployments.
