Abstract

The invention relates to the technical field of vehicle diagnosis, and discloses a vehicle system firmware safety protection method and device and computer equipment, the safety performance of firmware of each system of a vehicle is detected based on vehicle-mounted data, a detection report is generated, firmware safety risk information in the system can be known, and the safety performance of the system is improved. According to the firmware security risk information, the selection instruction is acquired according to the firmware security risk information, so that the diagnosis equipment enters the system corresponding to the firmware, the diagnosis equipment can conveniently extract and analyze the system data of the system, firmware protection data corresponding to the system data can be conveniently generated according to the acquired system data, and the system protection efficiency is improved. According to the firmware protection method, the firmware protection data is acquired and sent to the system, so that the system can perform security protection on the firmware in the system according to the firmware protection data, the security protection can be performed on the firmware which has a firmware security risk, original data of the firmware is prevented from being further maliciously tampered or key data is prevented from being leaked, and the security of the firmware is improved. And the safety of firmware in each system of the vehicle is improved.

Description

technical field [0001] The present application relates to the technical field of vehicle diagnosis, in particular to a vehicle system firmware security protection method, device and computer equipment. Background technique [0002] In modern automobiles, the two electronic systems of car body control and on-board service constitute the electronic system of the car. Among them, the on-board diagnostic system (On-Board Diagnosis System, OBD) equipment can be connected to the local area network of the car controller, and through the diagnosis session Initiate information acquisition or status control on the in-vehicle controller to help maintenance personnel quickly locate and repair faults in the vehicle. Due to the widespread use of OBD, damage to the device firmware will have an impact on car maintenance and even driving safety. In addition, OBD itself has a complex structure and is closely related to the communication and control of the vehicle. Therefore, it is difficult a...
