摘要

随着智能网联汽车(ICV)的不断发展和升级,智能网联汽车的车载网络通信已逐步从传统的CAN总线向CAN- fd、FlexRay、车载以太网等复杂的车载通信网络转变。然而,复杂的网络架构在极大提高通信性能的同时,也带来了潜在的网络安全风险。本文主要从车辆信息安全的角度研究了不同总线的安全性,提出了CAN总线和车载以太网的保护方法,并对其进行了保护设计验证。

Risk Analysis of CAN Bus and Ethernet Communication Security for Intelligent Connected Vehicles
With the continuous development and upgrading of Intelligent Connected Vehicles (ICV), the on-board network communication of intelligent connected vehicles has been gradually transformed from the traditional CAN bus to the complex on-board communication network such as CAN-FD, FlexRay and on-board Ethernet. However, while the complex network architecture brings the communication performance greatly improved, it also brings the hidden cyber security risk. This paper mainly studies the security of different buses from the perspective of vehicle information security, proposes the protection method of CAN bus and vehicle Ethernet, and carries on the protection design verification to them.
