    Abstract: An anomaly detection device is located between a network and a first ECU in the plurality of ECUs, and includes: a communication circuit; a processor; and a memory including a set of instructions that, when executed, causes the processor to perform operations including: receiving a message from the first ECU and transmitting the message to the network, and receiving a message from the network and transmitting the message to the first ECU, using the communication circuit; holding, in the memory, a received ID list; when an ID of the message received by the communication circuit from the network is not included in the received ID list, adding the ID to the received ID list; and when an ID of the message received by the communication circuit from the first ECU is included in the received ID list, causing the communication circuit not to transmit the message to the network.

    Abstract: In an anomaly detection method that determines whether each frame in observation data constituted by a collection of frames sent and received over a communication network system is anomalous, a difference between a data distribution of a feature amount extracted from the frame in the observation data and a data distribution for a collection of frames sent and received over the communication network system, obtained at a different timing from the observation data, is calculated. A frame having a feature amount for which the difference is predetermined value or higher is determined to be an anomalous frame. An anomaly contribution level of feature amounts extracted from the frame determined to be an anomalous frame is calculated, and an anomalous payload part, which is at least one part of the payload corresponding to the feature amount for which the anomaly contribution level is at least the predetermined value, is output.

    Abstract: An anomaly detection electronic control unit connected to an in-vehicle network includes: a communicator that receives a first communication message indicating speed information of a vehicle including the in-vehicle network and a second communication message indicating peripheral information of the vehicle; a processor; and a memory including at least one set of instructions that, when executed by the processor causes the processor to perform operations including: (A) determining a first traveling state of the vehicle based on the speed information and a second traveling state of the vehicle based on the peripheral information; (B) determining, by comparing the first traveling state with the second traveling state, that the first communication message is anomalous when the first traveling state is different from the second traveling state; and (C) executing processing to handle an anomaly when the first communication message is determined to be anomalous.

    Abstract: An electronic control unit connected to a bus of a first network where first-type frames are transmitted following a first communication protocol and a second network where second-type frames are transmitted following a second communication protocol in an onboard network system. The electronic control unit sequentially receives the first-type and the second-type frames from the bus and the second network respectively, and stores in first and second reception buffers, respectively. The electronic control unit sequentially generates first-type data and second-type data by referencing the contents of the first reception buffer and the second reception buffer, and stores the first-type and second-type data in first and second transmission buffers, respectively. The first-type data is traveling control data for a vehicle, and the second-type data is other data. The first-type or second-type data that is priority type data is transmitted with priority.
