Problems solved by technology

[0002] At present, with the increase of vehicle function requirements year by year, more and more electronic control devices are applied to automobiles, and each electronic control device is integrated into the vehicle network in the form of modules. Electronic control devices are inseparable from the security of the vehicle network. , the On Board Diagnostics (OBD) interface in the vehicle network is exposed to the outside, and there is a security risk in the vehicle network
[0003] At present, the automotive field is developing rapidly. Although the automotive general bus in the vehicle has the characteristics of reliable transmission, strong implementation and high flexibility, there are also huge security risks. External attack devices can conduct denial of service attacks on the entire vehicle network through the OBD interface. Attacks such as preempting the bus and changing controller data have an impact on vehicle safety and a real threat to the driver's life safety
