Safety control method, device and computer equipment

Abstract

The invention provides asafety control method, a device and a computer equipment, wherein the method comprises: obtaining a key generated according to ECU identity information of a vehicle control unit ECU to be authenticated and gateway identity information of a vehicle gateway, and generating check information corresponding to the ECU identity information;a key is used to encrypt the verification information to generate the first authentication information;receiving second authentication information generated based on the first authentication information transmitted by the ECU;the second authentication information is decrypted by using a key to obtain the carried check information and the ECU identity information;by judging whether the decrypted check information and the ECU identity information have a corresponding relationship, the ECU is verified securely. The gateway verifies each ECU securely with different verifying information and encrypts with different keys when transmittingthe verifying information, which makes the transmission process more secure, realizes the ECU security verification and ensures the communication security.

Description

technical field [0001] The invention relates to the technical field of vehicle safety communication, in particular to a safety control method, device and computer equipment. Background technique [0002] With the improvement of people's living standards, more and more vehicles are used by people. Various functions in the vehicle are realized by the electronic control unit ECU. If the ECU in the car is not legal or is controlled by hackers, then The life safety of passengers will be endangered, so the communication safety among the various ECUs in the car is particularly important. [0003] In related technologies, when communicating between ECUs, there is no identity authentication process, or a fixed software encryption algorithm with a relatively simple algorithm is used for authentication. Since the authentication algorithm is relatively simple, it is easy to be cracked, and the ECU is easily replaced by an illegal ECU. , leading to the communication security between ECU...

AI Technical Summary

Problems solved by technology

[0005] For this reason, the first purpose of the present invention is to propose a security control method. During each verification, the gateway generates verification information, and uses different verification information for each ECU to perform safety verification, avoiding the use of a single verification At the same time, when the verification information is transmitted, it is encrypted with different keys, making the transmission process more secure, realizing the legality verification of the ECU, ensuring the security of in-vehicle communication, and solving related problems. In the technology, the security verification of the identity is not performed when the ECU communicates, which leads to the technical problem that the communication security between the ECUs cannot be guaranteed
