초록
Recently, Various security techniques are developed to provide security for In-vehicle CAN, but the limited characteristics of CAN protocol make it hard to apply them to a real vehicle. In this paper, we propose a sender authentication and key management schemes considering the limitations of In-vehicle CAN. Our proposed security scheme is designed considering the computing power of automotive ECU and the limited-size CAN data frame. Further, we suggest an efficient key management scheme causing no communication overhead in a session key update process. The security scheme has a structure that may be implemented without change of CAN standards. To evaluate the performance and security of the proposed scheme, we conduct hardware and network simulator based evaluation. Finally, through the analysis on the security and performance, we prove that our proposed scheme is suitable for solving the problem of In-vehicle CAN authentication.
