    Abstract: An anomaly detection electronic control unit (ECU) that detects unauthorized messages on a communication path is provided. An ECU that periodically transmits a first-type message including data to be monitored, and an ECU that periodically transmits a second-type message including data for comparison, are connected to the communication path. The anomaly detection ECU includes: a receiver that successively receives first-type and second-type messages; a processor that determines whether a first-type message received is normal or anomalous; and a transmitter that transmits a predetermined message in accordance with results of the determining. The determining is performed based on content of the first-type message, content of a second-type message last received at the time of receiving this first-type message, and at least one of content of a first-type message received further in the past than this first-type message, and content of a second-type message received further in the past than the second-type message last received.

    Abstract: A security device connected to at least one bus in a vehicle is provided. The security device determines, with regard to a frame received from the at least one bus, whether predetermined conditions are satisfied to determine whether the frame is a suspect of being an attack frame. The security device transmits, a determination request to an external device outside of the vehicle in a case where the predetermined conditions are satisfied, and obtains determination results from the external device in accordance with the determination request. The security device outputs first presentation information in the case where the predetermined conditions are satisfied, and outputs second presentation information in a case where the determination results are obtained from the external device.

    Abstract: In a fraud-detection method for use in an in-vehicle network system including a plurality of electronic control units (ECUs) that exchange messages on a plurality of buses, a plurality of fraud-detection ECUs each connected to a different one of the buses, and a gateway device, a fraud-detection ECU determines whether a message transmitted on a bus connected to the fraud-detection ECU is malicious by using rule information stored in a memory. The fraud-detection ECU transmits an error message including a message identifier of a message determined to be malicious. The gateway device receives updated rule information transmitted to a first bus among the buses, selects a second bus different from the first bus, and transfers the updated rule information only to the second bus. A fraud-detection ECU connected to the second bus acquires the updated rule information and updates the rule information stored therein by using the updated rule information.

    Abstract: An anomaly handling method that suitably handles a case where the possibility of a vehicle being unauthorizedly controlled so as to suppress the effects thereof is provided. In an anomaly handling method used in one or a plurality of electronic control units installed in one vehicle, an inter-vehicle communication message transmitted from a device installed in the other vehicle is received as an anomaly detection notification, the anomaly detection notification being issued when an unauthorized frame is detected on an onboard network installed in another vehicle, and an anomaly handling processing is selected from a plurality of predetermined anomaly handling processing in accordance with the received content to transition to a safe state for example, and the selected anomaly handling processing is executed.
