A Security Framework for In-Vehicle FlexRay Bus Network

Jin-Hui Piao, Yu-Jing Wu, and Yi-Nan Xu

Abstract—With the continuous development of automotive electronic technology and the maturity of system integration technology, the real-time performance and security have attracted more and more attention in automotive industries. However, identically with other in-vehicle bus protocol (e.g. CAN, LIN and MOST), their security are not considered in the origin of design. Therefore, security of FlexRay bus is directly related to human's privacy and life. In this paper, we proposed a security framework for FlexRay network. Considering the limitation of computing resources and the real-time performance of in-vehicle ECUs, we optimize the original MAC(Message Authentication) algorithm. To strength the security level and robutness of the system, we recommend to use ECC (Elliptic Curves Cryptography) encryption algorithm and dual channel model for our security framework. By using our proposed model, the bandwidth can be reduced 25% and the computational time can decrease evidently.

Index Terms—In-vehicle network security, FlexRay, encryption, message authentication.
