Research of Authenticated Encryption Security Protocol for FlexRay In-vehicle Network

Meng-Zhuo Liu, Yi-Hu Xu, Yu-Jing Wu, and Yi-Nan Xu

Abstract—Since the appearance of internet of vehicle (IoV), the in-vehicles network is no longer an isolated system. The OBD-II hardware, GPS, and the WiFi system could cause intrusions during communications. There are many unresolved network security problems yet in in-vehicle bus protocol, like controller area network (CAN), local area network (LIN), and FlexRay. In this paper, having considered the vulnerabilities and a hidden attacking of FlexRay, an authenticated encryption protocol is designed based on the Advanced Encryption Standard (AES)-128 and SHA-1 algorithm for FlexRay. We apply the protocol into a simulated FlexRay bus system which is build by CAN software environment. The protocol is also applied in a real Flexray network build by MC9S12XF512 evaluation board The both experimental results show that the security and reliability of in-vehicle bus system are enhanced.

Index Terms—FlexRay, in-vehicle bus network, network reliability, security protocol.
