Packets implementing physical controls may pose a greater security threat to the vehicle than status message packets. Injecting these types of physical control messages will cause the vehicle to take actual actions, such as starting without applying the brakes Its braking system and the control command to crack the door lock realize the keyless door opening operation, resulting in theft of property in the car

The invention discloses a method for reverse testing a regular packet of a CAN bus, so as to realize the function verification of the regular packet, and then detect the security threat existing therein. The reverse testing method comprises: respectively acquiring conventional packets on the CAN bus under the vehicle dormant state and implementing functional operations on the vehicle; calculating the frame numbers of the conventional packets of each ID within the same duration under the vehicle dormant state and implementing functional operations on the vehicle, And calculate the difference between the number of regular packet frames of the same ID in the vehicle sleep state and the vehicle's functional operation; send the same data packet with the ID with the largest difference to the CAN bus to verify the ID of the largest difference The functionality of the regular package. In addition, the invention also discloses a CAN bus conventional packet reverse testing system, electronic equipment and a computer-readable storage medium.
Description
technical field [0001] The invention relates to the technical field of vehicle network security, in particular to a CAN bus conventional packet reverse testing method, system, electronic equipment and computer-readable storage medium. Background technique [0002] With the rapid development of Internet technology and vehicle manufacturing technology, the degree of intelligence and networking of vehicles has been continuously improved, and various convenient and fast vehicle services (such as navigation and positioning, real-time road conditions, social entertainment, vehicle condition monitoring, remote control, etc.) have been greatly improved. driving experience of the vehicle. But at the same time, more and more vehicle components are exposed to the Internet environment, causing vehicle terminals, Apps, electronic keys and OBD (On-Board Diagnostics, on-board diagnostic system) interfaces to become potential targets for attackers to attack vehicles. Entrance. Once these ...
