To improve the reliability of data access authentication.SOLUTION: An authentication system 1 comprises a plurality of on-vehicle devices 2 and an authentication server 3. When acquiring a diagnosis request, the authentication server 3 determines a first security level related to an access to data to be read of a vehicle for which an access is requested based on the type of an operator, an IP address, and a DID included in the diagnosis request. The DID indicates the type of the data to be read. The on-vehicle device 2 determines a second security level based on vehicle position information and the DID. When successful in verification using first and second keys for authentication generated based on the first and second security levels, the on-vehicle device 2 permits transmission of the data to be read from the on-vehicle device 2 to the authentication server 3.SELECTED DRAWING: Figure 1
【課題】データアクセス認証の信頼性を向上させる。【解決手段】認証システム１は、複数の車載装置２と認証サーバ３とを備える。認証サーバ３は、診断リクエストを取得すると、操作者の種別と、ＩＰアドレスと、診断リクエストに含まれるＤＩＤとに基づいて、アクセス要求の対象となる車両の読出対象データへのアクセスに関する第１セキュリティレベルを決定する。ＤＩＤは、読出対象データの種別を示す。車載装置２は、車両位置情報とＤＩＤとに基づいて、第２セキュリティレベルを決定する。車載装置２は、第１，２セキュリティレベルに基づいて生成された第１，２認証用鍵を用いた検証に成功した場合に、車載装置２から認証サーバ３への読出対象データの送信を許可する。【選択図】図１
