Security testing method for automotive ECU network

Abstract

A security testing method for ECU network includes: providing a host computer to simulate the key information given by the vehicle, and then simulating the notification to an ECU on the vehicle host through a CAN analyzer. Through data comparison, it is judged whether the key loading in the ECU is correct, whether encryption and decryption functions are successful, and whether the CMAC is complete. There is no need to test the whole vehicle host. It only needs the host computer and the CAN analyzer to complete, and the cost is greatly reduced. Moreover, the present invention is based on the C language platform, has high portability, is easy for secondary development, has a simple interface, and is easy to operate, and has high testing efficiency.
