针对车载CAN与CAN-FD网络的未授权传输安全问题，提出基于修改CAN控制器的高性价比硬件防护方法，可阻止ECU异常频率传输并经实验验证有效。
AI 中文摘要
近年来已有大量针对控制器局域网（CAN）的安全攻击案例被报道，但当前车载控制网络的电子控制单元（ECU）中未包含任何安全功能，因此车载控制网络尤其需要高性价比的安全特性。为此，本文提出一种方法，通过修改CAN控制器以阻止ECU以异常频率向CAN总线传输消息，从而阻断未授权的CAN总线访问。我们还验证了该防护机制在灵活数据速率CAN（CAN-FD）总线上的有效性。
英文摘要
There have been a quite number of security attack cases against Controller Area Network (CAN) reported in recent years, but in the meantime no security function is included in the ECU in the current in-vehicle control network. Thus, in-vehicle control networks particularly require cost-effective security features. In this paper, therefore, we propose a method to block unauthorized CAN-bus access using a CAN controller that is modified to prevent the ECU from transmitting messages to the CAN-bus at abnormal frequency. Then, we have also demonstrated the effectiveness of the disabler on CAN with flexible data-rate (CAN-FD) buses.
