Abstract—In order to improve road traffic safety, reduce congestion, improving driving experience, intelligent transportation systems and vehicular networking concepts arises at the historic moment. In vehicle larger density scene, can’t guarantee safe reliable and information transmission timely, sometimes can also cause problems such as the broadcast storm. Represented by LTE-A evolution of new generation of mobile communication network rapid development. It performance optimization in the system capacity, the peak rate, transmission delay and other key. In this paper, we proposed a privacy-preserving and cross-domain group authentication scheme. It can effectively solve the security problems. Theoretical analysis and simulation results are shown that compared with other authentication protocol, our scheme has more security properties and better performance.
