Abstract: To solve the security and efficiency problem of the existing privacy protection schemes in vehicular network, a new privacy protection scheme was proposed based on security multi-party computation and anonymous authentication. Because of linear equations and secure and efficient oblivious transfer mechanism, the traditional public key cryptography algorithm is avoided. It is shown that the proposed scheme not only can fulfill multiple security requirements, such as privacy of sender, privacy of receiver, anonymity, collusion attack, replay attack, etc, but also can improve the authentication efficiency. The scheme is of significance and application value in limited computational performance environments such as Internet of Things.

Key words: secure multi-party computation, vehicular Ad hoc network, privacy protection, anonymous authentication
