The invention provides a fusion detection system for automobile network attacks. The fusion detection system comprises an automobile body state abnormity detection module, an automobile network attack detection module and an automobile network attack detection module. The automobile body state abnormity detection module acquires original state signal data of an automobile and converts the original state signal data into action data; performing aggregation processing to obtain first feature data; inputting the received current state signal data into a first training model to obtain a first output result; the uplink and downlink flow time sequence anomaly detection module collects automobile flow data; performing aggregation processing on the flow types, the flow sizes and the component IDs of the different components to obtain second feature data; inputting the received current automobile flow data into a second training model to obtain a second output result; the network connection time sequence anomaly detection module collects network connection data of the automobile; performing feature construction according to the quintuple to obtain third feature data; inputting the collected current network connection data into a third training model to obtain a third output result; and the fusion decision module carries out fusion processing on the first to third output results and judges whether the vehicle is abnormal or not.

    本发明提供了一种汽车网络攻击的融合检测系统,包括:车身状态异常检测模块获取车辆的原始状态信号数据并转换为动作数据;进行聚合处理,得到第一特征数据;将接收到的当前状态信号数据输入第一训练模型,得到第一输出结果;上下行流量时序异常检测模块采集汽车流量数据;对不同部件的流量类型、流量大小和部件ID进行聚合处理,得到第二特征数据;将接收到的当前汽车流量数据输入第二训练模型,得到第二输出结果;网络连接时序异常检测模块采集汽车的网络连接数据;根据五元组进行特征构建得到第三特征数据;将采集到的当前网络连接数据输入第三训练模型,得到第三输出结果;融合决策模块对第一至第三输出结果进行融合处理,判断车辆是否异常。
