An integrated distributed electric vehicle controller security communication method and system

Abstract

Abstract The invention relates to a secure communication method of integrated distributed electric vehicle controllers. According to the communication method, a gateway is configured in an electric vehicle controller network, vehicle-mounted electric control units in the electric vehicle controller network are connected with the gateway to constitute integrated distributed architecture for communication with an external network, and a first white 5 box encryption algorithm is built in the gateway to encrypt data packet transmission among the vehicle-mounted electric control units in real time. By adoption of the secure communication method provided by the present invention, the data information transmission among the vehicle-mounted electric control units can be monitored and controlled in real time, the white box breaking and decoding of sensitive driving information and keys are effectively defended, and the security of data transmission is improved.

Description

technical field [0001] The invention relates to the technical field of safe communication strategies for vehicle-mounted local area networks, in particular to a method and system for safe communication of integrated distributed electric vehicle controllers. Background technique [0002] With the rapid development of automobile function diversification and integration, especially with the vigorous promotion and use of electric vehicles, the increase and use of on-board electronic equipment, especially the application of electronic car locks, has gradually become popular in the mass market. While the application of on-board electronic equipment has greatly improved the safety factor of traditional vehicles, it has also brought new hidden dangers to the safety of vehicles. Destruction is even used to illegally steal private information, resulting in the leakage of driving electronic control information, the decoding of the lock code and other serious consequences. In view of t...
