Risk Analysis of CAN Bus and Ethernet Communication Security for Intelligent Connected Vehicles

Abstract

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.
