| 摘 要： | CAN由于其突出的可靠性和灵活性，已成为当代汽车应用最广泛的现场总线。但是标准CAN协议没有提供足够的安全措施，易遭受窃听、重放、泛洪、拒绝服务攻击。为了有效检测 CAN 总线是否遭受到攻击，并在遭受泛洪攻击时将恶意报文滤除。对车载 CAN 总线报文通信特征进行了分析，提出一种入侵检测方法，该方法可以有效进行入侵检测、恶意报文滤除。通过实验验证，该方法可以100%检测出CAN总线是否遭受攻击，恶意报文过滤的准确率可达99%以上。

| Abstract: | CAN has become the most extensive fieldbus for contemporary automotive applications due to its outstanding reliability and flexibility.However,the standard CAN protocol does not provide sufficient security measures and is vulnerable to eavesdropping,replay,flooding,and denial of service attacks.In order to effectively detect whether the CAN bus is attacked,and to filter malicious messages when subjected to flooding attacks.The characteristics of vehicle CAN bus message communication were analyzed,and an intrusion detection method was proposed,which could effectively perform intrusion detection and malicious message filtering.Through experimental verification,the method can detect whether the CAN bus is attacked by 100%,and the accuracy of malicious packet filtering can reach over 99%. |
