An improved method for reverse engineering ECU firmware

We found that there are existing academic studies on reverse engineering the firmware that implements Bluetooth and USB protocols to study their security. Electronic Control Unit (ECU) firmware implements the Controller Area Network (CAN) protocol, which is commonly used to implement the communication of the vehicle’s internal network. With the development and growth of electric vehicles, the security of the vehicle network is becoming increasingly important. This paper proposes a method to reverse engineer ECU firmware, which can efficiently help us quickly identify the library functions in the firmware and reduce the errors that may occur during reverse engineering.
