Abstract

The controller area network (CAN) is one of the most popular intra-vehicular communication protocols in the automotive industry. Due to its simplicity and broadcasting technique, the CAN bus protocols have some vulnerabilities. In the last couple of years, security attacks on vehicles have been increasing significantly. These acute attacks remain undetected by the conventional CAN protocol. In this paper, we propose a method that can prevent many kinds of CAN bus monitoring attacks without any change in the underlying CAN protocol. The experimental results demonstrate that our proposed methodology is useful for preventing as well as defending against attacks on the CAN bus. In the worst-case scenario, the proposed algorithm requires 0.41 s to detect an attack and prevent the attack by dynamically updating the message arbitration ID of a system comprising twelve types of message IDs.
