PROBLEM TO BE SOLVED: To effectively improve security of a vehicle.SOLUTION: A gateway ECU 12 receives a frame transmitted from an external device (for example, an unauthorized device 26) of a vehicle 10. The gateway ECU 12 determines whether the received frame is authorized on the basis of an ID set to the received frame. When the gateway ECU 12 determines that the received frame is authorized, the gateway ECU 12 transfers the received frame to a processing ECU 14, and when the gateway ECU 12 determines that the received frame is unauthorized, the gateway ECU 12 transfers the received frame to a dummy ECU 16. The dummy ECU 16 transmits a positive response for the frame determined to be unauthorized to the external device (for example, the unauthorized device 26) that is the transmission source of the frame.SELECTED DRAWING: Figure 1

    【課題】車両のセキュリティを効率的に向上する。【解決手段】ゲートウェイECU12は、車両10の外部装置(例えば不正装置26)から送信されたフレームを受信する。ゲートウェイECU12は、受信フレームに設定されたIDに基づいて、受信フレームが正当か不正かを判定する。ゲートウェイECU12は、受信フレームを正当と判定した場合、受信フレームを処理ECU14へ転送し、受信フレームを不正と判定した場合、受信フレームをダミーECU16へ転送する。ダミーECU16は、不正と判定されたフレームに対する肯定的な応答を、当該フレームの送信元である外部装置(例えば不正装置26)へ送信する。【選択図】図1
