    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, when an unauthorized frame is detected on an onboard network installed in another vehicle, an inter-vehicle communication message transmitted from a device installed in the other vehicle is received as an anomaly detection notification, and an anomaly handling processing is selected from a plurality of predetermined anomaly handling processing in accordance with the received content (e.g., step S304 in level determination) to transition to a safe state for example, and the selected anomaly handling processing is executed (e.g., steps S305 through S311).

    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 bus and a fraud-detection ECU connected to the bus, the fraud-detection ECU includes a memory that stores rule information indicating a rule regarding transmission of a message to be transmitted on the bus, the fraud-detection ECU determines whether or not a message transmitted on the bus is malicious by using the rule information, and, in a case where the message is malicious, transmits an error message including a message identifier of the malicious message. The fraud-detection ECU acquires updated rule information transmitted from an external server, and updates the rule information by using the updated rule information.
