The invention discloses an information security monitoring system and method of a vehicle internal network system. A first exclusive identification code and a second exclusive identification code areset in an electronic control unit in a vehicle, and a second exclusive identification code is set in a warning unit; the electronic control unit monitors other control messages in the CAN network at any moment except for sending the first control message of the electronic control unit, if the other control messages are monitored to contain the first exclusive identification code, the other controlmessages are judged to be illegal messages, and a warning message containing a second exclusive identification code is sent; and when the warning unit receives a warning message containing the secondexclusive identification code, a warning signal is sent out. The exclusive identification code is set in the electronic control unit in the vehicle, whether an external illegal message exists or notis judged by monitoring whether the message which is not sent by the vehicle contains the identification code or not, safety monitoring of the CAN network information of the vehicle is achieved, and the method is simple, reasonable and effective.

    本发明公开了一种车辆内部网络系统的信息安全监控系统及方法。它在车辆内部的电子控制单元中设置第一专属识别码和第二专属识别码,在警示单元中设置第二专属识别码;电子控制单元在发送自身第一控制报文以外的任何时刻监控CAN网络中的其他控制报文,若监控到其他控制报文中包含所述第一专属识别码,则判断该其他控制报文为非法报文,发送包含第二专属识别码的警示报文;警示单元接收到包含第二专属识别码的警示报文时,则发出警示信号。本发明在车辆内部的电子控制单元中设置专属识别码,通过监控非自身发送的报文中是否包含该识别码来判断是否有外来非法报文,实现车辆CAN网络信息的安全监控,方法简单,合理有效。
