英文摘要 | As the infrastructure of intelligent transportation systems, Vehicular Ad hoc Networks (VANETs) improve the efficiency of transportation. Meanwhile, key management and privacy leakage of users in VANETs are two vital security aspects. It is extremely important to perform these actions promptly and efficiently. Based on the idea of batch authentication and ring signcryption, a conditional privacy protection scheme of anonymous multi-receiver is proposed in this paper. On the one hand, the scheme with ring list selection has an optional privacy level. On the other hand, the blockchain prevents the single point of failure problem in key management and shares the public keys of vehicles promptly in Road Side Units (RSUs). Finally, experiments show that the proposed scheme has higher efficiency with certain security as the security analysis shows.
