Title (EN) LOCATION GUARANTEEING SYSTEM
(FR) SYSTEME DE GARANTIE DE POSITION
(JA) 位置保証システム
Abstract: front page image
(EN)It is possible to strictly guarantee that a mobile body was at a certain location at a certain time. A location module Mi sends an identifier (IDi) to a location server Sxyz to request for location guarantee. The location server Sxyz creates a signature for a message formed by the location information, the time information, the identifier of the location server Sxyz, and the location module identifier by using a secret key of the location server Sxyz. By adding the signature to the message to create a location certificate, which is sent to the location module Mi. The location module Mi sends the location certificate to a verifier V. The verifier V verifies the signature of the location certificate by using a public key of the location server Sxyz. If the verification is successful, the location information and the time information are received.
(FR)Grâce à cette invention, il est possible de garantir absolument qu’un corps mobile se trouvait à une position donnée à un moment donné. Un module de position Mi envoie un identifiant (IDi) à un serveur de position Sxyz pour demander une garantie de position. Le serveur de position Sxyz crée une signature pour un message constitué par les informations de position, les informations de temps, l’identifiant du serveur de position Sxyz, et l’identifiant du module de position en utilisant une clé secrète du serveur de position Sxyz. La signature est ajoutée au message pour créer un certificat de position qui est transmis au module de position Mi. Le module de position Mi transmet le certificat de position à un vérificateur V. Le vérificateur V vérifie la signature du certificat de position en utilisant une clé publique du serveur de position Sxyz. Si la vérification est positive, les informations de position et les informations de temps sont reçues.
(JA) 移動体がある時刻にある位置に存在したことを厳密に保証する。  位置モジュールMiは、位置サーバSxyzに識別情報(IDi)を送り、位置保証を依頼する。位置サーバSxyzは、位置情報と時刻情報と自己の識別情報と位置モジュールの識別情報からなるメッセージについて、位置サーバSxyzの秘密鍵を使って署名を作成する。メッセージに署名を付加した位置証明書を生成して、位置モジュールMiに送る。位置モジュールMiは、位置証明書を検証者Vに送る。検証者Vは、位置サーバSxyzの公開鍵を使って、位置証明書の署名を検証する。検証が成功すれば、位置情報と時刻情報を受理する。
