Abstract

The invention provides a node identity authentication method and system suitable for Internet of Vehicles, and the method comprises a registration application step: enabling a vehicle unit to apply for registration to an RSU, and obtaining registration application result information; an RSU verification step: the RSU verifies the vehicle identity corresponding to the vehicle unit, and obtains thecorresponding vehicle identity verification result information; acquiring legal public key table broadcast information according to the corresponding vehicle identity verification result information;and a legal public key table updating step: according to the legal public key table broadcast information and the vehicle local legal public key table parameters, comparing the legal public key tablebroadcast information with the vehicle local legal public key table parameters, updating the vehicle local legal public key table, and obtaining legal public key table updating result information andvehicle unit identity confirmation result information. According to the scheme based on the legal public key table, more messages can be verified in unit time, and higher efficiency is achieved.

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...
