摘要： 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.

摘要： An anomaly detection electronic controller performs anomaly detection processing and is connected to a bus, which a plurality of electronic controllers use for communication to communicate following a Controller Area Network (CAN) protocol. The anomaly detection electronic controller includes an anomaly detection processor that performs anomaly detection processing regarding a data frame. The anomaly detection controller also includes an anomaly detection processing requester that decides an anomaly detection processing timing in accordance with a state of a vehicle in which the bus is installed when receiving the data frame, the anomaly detection processing timing being a reception timing of one or multiple fields in the data frame. The anomaly detection processor further performs the anomaly detection processing regarding the data frame at the anomaly detection processing timing decided by the anomaly detection processing requester.

摘要： 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.

摘要： An electronic control unit is connected to an in-vehicle network bus in an in-vehicle network system including a plurality of apparatuses that perform communication of frames via the bus. The electronic control unit includes a first control circuit and a second control circuit. The first control circuit is connected to the bus via the second control circuit over wired communication and/or wireless communication. The second control circuit performs a first determination process on a received frame received from the bus to determine the conformity with a first rule related to at least a reception interval, and, upon determining that the received frame conforms to the first rule, executes a predetermined process based on the content of the received frame. The first control circuit performs a second determination process on the received frame, received via the second control circuit, to determine the conformity with a second rule different from the first rule.

摘要： An anti-fraud method for use in an in-vehicle network system including a plurality of electronic control units that exchange data frames, each having added thereto a message authentication code (MAC), via a bus includes receiving a data frame transmitted on the bus, and generating a first MAC by using a MAC key and a value of a counter that counts a number of times a data frame having added thereto a MAC is transmitted. The method also includes performing verification that the data frame received has added thereto the generated first MAC and incrementing a number of error occurrences when the verification has failed for the data frame, the data frame including a predetermined message ID. When the number of error occurrences exceeds a predetermined threshold, a process associated in advance with the predetermined message ID is executed.
