【Abstract】 In order to realize identity authentication and key distribution in Internet of Vehicle(IOV) scenario, this paper proposed an enhanced identity authentication scheme for the IOVs based on extended quantum key distribution. The features of this scheme are:(1) Quantum key mobile distribution was completed through quantum security module and preset quantum key in wireless communication, online negotiation of quantum key was completed through Quantum Key Distribution(QKD) equipment in wired communication, to achieve extended quantum key distribution;(2) Basic identity authentication based on post-quantum cryptography encryption and signature algorithms was conducted, and enhanced authentication through preset quantum keys.Finally, through security analysis and performance testing, it is confirmed that this scheme has sufficient security and low computational overhead. The total computational overhead is 1.689 ms, and the performance improvement is 60.43%～70.72%.更多还原
