Certificate-based vehicle identity authentication method in Internet of Vehicles

Abstract

The invention relates to a certificate-based vehicle identity authentication method in the Internet of Vehicles. Vehicles use time-sensitive certificates issued by regional servers instead of their real identities to achieve independent authentication of vehicle identities. The vehicle sends the detected identity information of the malicious vehicle to the regional server. After receiving the identity of the malicious vehicle and its signature, the regional server traces the regional registration information of the real identity of the vehicle and sends the information to the authentication center, which confirms the identity of the malicious vehicle. The true identity of the vehicle and revoke its identity. The identity authentication method proposed by the present invention solves the attack detection delay caused by the inability of the vehicle to independently complete the identity authentication process in the existing Sybil attack detection method, as well as the extra space and calculation overhead caused by the revocation of the vehicle identity, and realizes the independence of the vehicle identity Authentication and privacy protection, and the ability to trace the true identity of malicious vehicles to prevent malicious vehicles from launching attacks again.

Description

technical field [0001] The invention belongs to the field of vehicle identity authentication in the Internet of Vehicles, and in particular relates to a certificate-based vehicle identity authentication method. Background technique [0002] Vehicle identity authentication technology is the basis of Internet of Vehicles services. Without identity authentication technology, vehicles cannot judge the authenticity and validity of received messages, and under the influence of Sybil attacks launched by malicious vehicles, vehicles will make wrong judgments and cause serious damage. traffic accident. [0003] At present, in the existing Sybil attack detection technology, the vehicle needs the help of the roadside infrastructure (RSU) to complete the vehicle identity authentication. These technologies are used in an Internet of Vehicles environment where RSUs are sparsely arranged. Malicious vehicles launch Sybil attacks in an environment where there are no RSUs nearby. The attacke...

AI Technical Summary

Problems solved by technology

However, the number of identities in the vehicle identity revocation list will increase over time, which not only increases the storage overhead of the vehicle, but also increases the authentication overhead in some methods, and these overheads are not helpful to the Internet of Vehicles service.
