Automobile electronic identification and V2X authentication combined method

Abstract

The invention relates to the technical field of V2X authentication, and discloses an automobile electronic identifier and V2X authentication combined method. The method comprises the steps of S1, obtaining a unique vehicle identifier; S2, applying for a registration certificate of the vehicle-mounted unit by using the unique vehicle identifier; S3, applying for a security certificate corresponding to the V2X device by using the registration certificate. According to the invention, the automobile electronic identifier is used as the unique identifier of the vehicle-mounted unit for applying for the security certificate, so that the credibility and reliability of the V2X data are ensured, the overall application process is simple, and the vehicle network equipment has a safe and reliable communication mode.

Description

technical field [0001] The invention relates to the technical field of V2X authentication, in particular to a method for combining automotive electronic identification and V2X authentication. Background technique [0002] Vehicle-road coordination is the latest development direction of intelligent transportation system, which adopts advanced wireless communication and new-generation Internet technologies. In the V2X business, the secure communication of the V2X communication system is handled by the application layer, which is responsible for certificate application, certificate storage, secret key management, message signature and signature verification and other functions. [0003] In V2X business, V2X devices exchange data information through Uu port or PC5 interface to realize important data exchange in various application scenarios. Communication security is very important. Only safe and reliable data information can achieve safe, efficient, and improved performance. T...

Problems solved by technology

[0004] The safety certification process of the existing technology is complicated, different certification processes are used for the on-board units that require privacy protection and non-privacy protection, and the certification system architecture is different, and those that require privacy protection The vehicle-mounted unit adopts the KPI (Public Key Infrastructure) certification system architecture, and the non-privacy-protected vehicle-mounted unit adopts the IBC (Identity-Based Cryptograph) certification system framework. The identity authentication system and method of vehicle-road coordination, although the authentication method integrates the existing KPI system and IBC technology, makes the authentication based on IBC technology as a whole, uses the security module embedded in the device to generate a public-private key pair, and uses the private key Sign the car electronic identification card number, and then apply to the CA certification body

Although the authentication process has been simplified to a certain extent, the overall authentication process is still cumbersome and prone to security risks, such as:

[0005] 1. The device uses its own generated key to sign KH1, which is not credible;

[0006]Second, the KH2 read by the radio frequency reading and writing device has the risk of tampering during transmission to the vehicle-mounted unit. To sign, there is a possibility of forgery, that is, use KH1 to replace KH2 and then sign

[0007] To sum up, the CA authentication request of the vehicle-mounted unit in the prior art is untrustworthy, and the security certificate of the obtained V2X device does not have the uniqueness of security verification , and the overall certification process is cumbersome
