Safety control method, device and computer equipment

Abstract

The present invention proposes a security control method, device and computer equipment, wherein the method includes: acquiring a key generated according to the ECU identity information of the vehicle control unit ECU to be authenticated and the gateway identity information of the vehicle gateway, and generating the corresponding ECU identity information The verification information is encrypted with the key to generate the first verification information, and the second verification information generated based on the first verification information sent by the ECU is received, and the second verification information is decrypted with the key to obtain the carried verification information. The verification information and ECU identity information, by judging whether the verification information obtained by decryption has a corresponding relationship with the ECU identity information, the security verification of the ECU is performed. In each verification, the gateway uses different verification information for each ECU to perform security verification. At the same time, when the verification information is transmitted, it is encrypted with different keys, which makes the transmission process more secure, realizes the security verification of the ECU, 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
