    Abstract: 【課題】CANプロトコル等に従って通信する車載ネットワークシステムにおいて、MACに対する総当たり攻撃への耐性を高め、不正なフレームの送信に対して適切に対処する不正対処方法を提供する。【解決手段】車載ネットワークにおいてMACが付加されたデータフレームの授受を行う複数の電子制御ユニットを備える車載ネットワークシステムにおいて用いられる不正対処方法は、車載ネットワークに送信されたデータフレームを受信する受信ステップ(シーケンスS4004)と、データを利用してMACを生成して、受信ステップで受信されたデータフレームに当該MACが付加されていることを検証する検証ステップ(シーケンスS4005)と、検証ステップでの検証が失敗した場合に、MACの生成に利用されるデータについての更新処理を行う更新処理ステップ(シーケンスS4007等)とを含む。【選択図】図43

    Abstract: 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 MAC, via a bus includes a receiving step of receiving a data frame transmitted on the bus, a verification step of generating a MAC by using data and verifying that the data frame received in the receiving step has added thereto the MAC, and an update processing step of performing an update process on the data used for generating the MAC in a case where verification has failed in the verification step.

    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.
