Abstract:
(EN) A vehicle-mounted computer generates a message authentication code concerning a log of the computer using the computer's signing key, and transmits a message authentication code-attached log to a vehicle information collection device. The vehicle information collection device generates a signing key of the vehicle-mounted computer, uses the generated signing key to verify the message authentication code of the message authentication code-attached log received from the vehicle-mounted computer, and if the verification of the message authentication code is successful, stores the log in a storage unit.
(FR) Selon l'invention, un ordinateur embarqué génère un code d'authentification de message concernant un journal de l'ordinateur à l'aide de la clé de signature de l'ordinateur, et transmet un journal attaché au code d'authentification de message à un dispositif de collecte d'informations de véhicule. Le dispositif de collecte d'informations de véhicule génère une clé de signature de l'ordinateur embarqué, utilise la clé de signature générée pour vérifier le code d'authentification de message du journal attaché au code d'authentification de message reçu de l'ordinateur embarqué et, si la vérification du code d'authentification de message est concluante, enregistre le journal dans une unité de stockage.
(JA) 車載コンピュータは、自己のログについてのメッセージ認証符号を、自己の署名鍵を使用して生成し、メッセージ認証符号付きログを車両情報収集装置に送信し、車両情報収集装置は、車載コンピュータの署名鍵を生成し、車載コンピュータから受信したメッセージ認証符号付きログのメッセージ認証符号を、該生成した署名鍵を使用して検証し、メッセージ認証符号の検証が合格したログを記憶部に格納する。
