Abstract

The embodiment of the invention discloses a CAN signal analysis method and system. The method includes: the encryption device encrypts the target original CAN signal according to the preset encryption method to obtain the target encrypted CAN signal, and transmits the target encrypted CAN signal to the signal analysis end; wherein the preset encryption method is loaded on the encrypted In the device, the preset encryption method includes modifying the information of the original CAN signal; the signal analysis terminal analyzes the target encrypted CAN signal according to the encryption analysis protocol to obtain a valid target signal; the encryption analysis protocol is based on the It is obtained by encrypting the original analysis protocol with a preset encryption method, and the original analysis protocol is used to analyze the original CAN signal to obtain a corresponding valid signal. This embodiment can prevent the leakage of the analysis protocol.

Description

technical field [0001] Embodiments of the present invention relate to the field of vehicle CAN signals, in particular to a CAN signal analysis method and system. Background technique [0002] CAN (Controller Area Network, Controller Area Network) is one of the most widely used field buses in the world, especially in the backbone network of automobiles. Analyzing effective key vehicle parameters from international advanced vehicle CAN signals is of great value to the development of electric vehicles and fuel cell vehicles in my country. The protocol provider spends a lot of time and energy to crack the CAN signal analysis protocol of the target model, and provides the CAN signal analysis protocol to the authorized car company to carry out the benchmarking analysis of the model. [0003] In the existing technology, the CAN signal analysis protocol is mostly represented as a protocol file, and the use method is simple and easy to learn. After some authorized car companies obta...
