Method and system for credible authentication between modules in intelligent networked vehicle

Abstract

The invention discloses a trusted computing-based method for security authentication between internal modules of an intelligent networked vehicle. The method comprises the processes of system initialization, certificate generation and verification, mutual authentication and key agreement between the modules, rapid message authentication, variable node module revocation and the like. According to the invention, a trusted computing technology is used for guaranteeing the security and credibility of the modules, remote certification is used for verifying the security states of the modules, and efficient message authentication is adopted. According to an intelligent networked vehicle communication model in the invention, module authentication and rapid message authentication can be realized. Whether the modules are in a safe state or not only needs to be verified periodically, and rapid message authentication of the modules can meet the requirement for verification of a large amount of real-time data in the intelligent networked vehicle.

Description

technical field [0001] The invention belongs to the communication security technology of intelligent networked vehicles, and in particular relates to a trusted authentication method and system between modules in intelligent networked vehicles. Background technique [0002] With the development of computer control technology, intelligent networked vehicles have gradually become a research hotspot. Intelligent networked vehicles mainly rely on the computer system in the car to realize unmanned driving. Intelligent networked vehicles mainly include three parts: data perception, data processing and control execution. Various sensors equipped in the vehicle are responsible for collecting real-time data, and the vehicle computing and communication unit (VCU) is responsible for processing the data received from the sensors, making timely decisions and finally sending them to the actuators. The actuator is responsible for receiving instructions collected from the VCU to implement ...
