Abstract:
(EN) Disclosed is a wireless communication system which is to be premised on one-way communication from a wireless terminal, and which simply and safely performs authentication on the wireless terminal. This wireless communication device is provided with a decryption unit and an authentication unit. The decryption unit decrypts encrypted node position information with an own secret key of the wireless communication device. This encrypted node position information is included in transmission information transmitted through the one-way communication from a node. The authentication unit performs an authentication process on a node under an authentication condition in which the decrypted node position information indicates an inside of a prescribed area.
(FR) L'invention concerne un système de communication sans fil basé sur une communication unidirectionnelle à partir d'un terminal sans fil, le système étant apte à exécuter une authentification sur le terminal sans fil simplement et en toute sécurité. Le dispositif de communication sans fil selon l'invention comprend une unité de déchiffrement et une unité d'authentification. L'unité de déchiffrement déchiffre des informations de position de nœud chiffrées avec une clé secrète propre au dispositif de communication sans fil. Les informations de position de nœud chiffrées sont incluses dans des informations de transmission transmises via la communication unidirectionnelle à partir d'un nœud. L'unité d'authentification exécute un processus d'authentification sur un nœud dans une condition d'authentification dans laquelle les informations de position de nœud déchiffrées indiquent l'intérieur d'une zone prescrite.
(JA) 無線端末からの片方向通信を前提とした無線通信システムにおいて、簡単かつ安全に無線端末の認証を行う。 無線通信装置は、復号部と認証部とを具備する。復号部は、暗号化ノード位置情報を、その無線通信装置自身の秘密鍵により復号する。この暗号化ノード位置情報は、ノードから片方向通信により送信された送信情報に含まれる情報である。認証部は、復号されたノード位置情報が所定のエリア内を示すことを認証条件としてノードの認証処理を行う。
