Abstract: For the security and efficiency of anonymous authentication in vehicular networks, an identity-based anonymous authentication scheme for vehicular networks is proposed by using bilinear pairing theory. The security of the scheme is further enhanced and the load of the trusted center is reduced by collaborating between the tamper-proof device of the onboard unit and the trusted center, the efficiency of the anonymous authentication of the onboard network is improved by batch verification. Security and efficiency analysis show that the scheme not only satisfies the security characteristics of anonymity, unforgeability and non-repudiation, but also has better time complexity and space complexity. The simulation results show that the scheme has certain advantages in both effectiveness and feasibility.

Key words: identity-based, vehicular network, anonymous authentication, random oracle model
