Abstract

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.
改进的 ECU 固件逆向工程方法
我们发现,目前已有学术研究对执行蓝牙和 USB 协议的固件进行逆向工程,以研究其安全性。电子控制单元(ECU)固件实现了控制器局域网(CAN)协议,该协议通常用于实现汽车内部网络的通信。随着电动汽车的发展和壮大,汽车网络的安全性变得越来越重要。本文提出了一种对 ECU 固件进行逆向工程的方法,可以有效地帮助我们快速识别固件中的库函数,减少逆向工程中可能出现的错误。
