Zusammenfassung: | To provide a relay device and a vehicle communication method capable of improving security in an in-vehicle network.SOLUTION: A relay device 100 includes: an authentication processing unit 140 that is mounted on a vehicle equipped with a TCU 200A, an in-vehicle ECU 200B, and an in-vehicle ECU 200C which are a plurality of functional units in an in-vehicle network, and acquires authentication information for the functional units from an external device outside the vehicle, and performs authentication processing for the functional units using the acquired authentication information; and a relay processing unit 120 that relays information between the functional units on the basis of a result of the authentication processing by the authentication processing unit. When the validity of the authentication information expires, the authentication processing unit acquires new authentication information from the external device.SELECTED DRAWING: Figure 4
【課題】車載ネットワークにおけるセキュリティを向上させることが可能な中継装置および車両通信方法を提供する。【解決手段】中継装置100は、車載ネットワークにおける複数の機能部であるTCU200A、車載ECU200B及び車載ECU200Cを備える車両に搭載され、機能部の認証情報を車両の外部における外部装置から取得し、取得した認証情報を用いて機能部の認証処理を行う認証処理部140と、認証処理部による認証処理の結果に基づいて、機能部間の情報を中継する中継処理部120と、を備え、認証処理部は、認証情報の有効期限が切れた場合、外部装置から新たな認証情報を取得する。【選択図】図4 |
