摘要
车联网在交通管理、信息服务等方面有广泛的应用前景,车内网的安全决定了用户能否安全、可靠地使用车联网的服务。为增强车内网安全,提出了应用于CAN总线的异常检测算法。算法适应CAN总线通信的特点,能够检测总线中的异常帧。此外,设计了异常检测系统的结构,能够接入CAN总线,可以应用于车内网,也可以应用于其它基于CAN总线的工业控制系统。实验结果表明,此系统可以有效的检测异常帧。
VANET （Vehicular Ad Hoc Network） enjoys comprehensive application prospect in traffic management, information service, ere. The security of the in-vehicle communication system determines the secure and reliable user experience of VANETs. In order to enhance the security of in-vehicle communication system, an anomaly detection algorithm applied to CAN （Controller Area Network） is proposed. This algorithm adapts to the characteristics of CAN bus communication, and could detect the abnormal frame in the bus. In addition, the structure of anomaly detection system is designed to access CAN bus, and applicable to intranet, and other CAN -based industrial control system. Experiment results indicate that this system could effectively detect abnormal frames.
