A roaming authentication protocol based on Elliptic Curve Cryptography in IOV

With the development of Internet of Vehicles, security and privacy issues have become a research hotspot. As the specific application of IOV, roaming service also faces privacy threats such as position sensitive information leakage. In this paper, we propose a framework of roaming authentication protocol based on Elliptic Curve Cryptography system in the scene of roaming scene in IOV. We describe the registration, login, authentication process systematically in order to obtain outside services from hometown to another place. In the security analysis, we use SVO to prove the security of the protocol. Through the comparison of the simulation data with existing protocols, the proposed protocol framework is proved to have a low computational cost.
