Node identity authentication method and system applicable to Internet of Vehicles

Abstract

The invention provides a node identity authentication method and system applicable to the Internet of Vehicles, including: registration application step: the vehicle unit applies for registration to the RSU, and obtains registration application result information; RSU verification step: the RSU verifies the vehicle identity corresponding to the vehicle unit, and obtains Corresponding vehicle identity verification result information; according to the corresponding vehicle identity verification result information, obtain legal public key table broadcast information; legal public key table update steps: according to legal public key table broadcast information, vehicle local legal public key table parameters, legal public key table The table broadcast information is compared with the local legal public key table parameters of the vehicle, the local legal public key table of the vehicle is updated, and the update result information of the legal public key table and the vehicle unit identity confirmation result information are obtained. The scheme based on the legal public key table of the present invention can verify more messages per unit time, and has higher efficiency.

Description

technical field [0001] The present invention relates to the communication field of the Internet of Vehicles, in particular to a node identity authentication method and system suitable for the Internet of Vehicles. Background technique [0002] In recent years, with the development of intelligent transportation and the maturity of 5G technology, the Internet of Vehicles has received extensive attention. In the Internet of Vehicles, there are three typical communication scenarios, namely vehicle-to-vehicle communication (V2V), vehicle-to-roadside unit (RSU) communication (V2R), and vehicle-to-cloud communication (V2I). Due to the interaction of sensitive information such as vehicle position and speed in the Internet of Vehicles, and the vehicle will formulate a series of strategies through the received messages broadcast by surrounding vehicles, once it is attacked by Sybil, replay, etc., it will receive tampered and forged information , causing serious damage to the safety o...
