Abstract

Selon l'invention, dans un dispositif de commande, une unité de communication (24) réalise une communication sans fil entre des terminaux de communication portables (4, 6) ayant une fonction de clé électronique. Une unité d'authentification (22, S100-S130) compare les informations de clé de clés électroniques par l'intermédiaire d'une unité de communication et, lorsque la comparaison d'informations de clé a été établie, le terminal avec lequel l'unité de communication a réalisé une communication sans fil est déterminé comme étant une clé électronique permettant l'actionnement d'un appareil, et l'actionnement d'un appareil est autorisé. Une unité de stockage (22a) stocke les informations de clé d'une clé électronique principale pour l'actionnement d'un appareil, en tant qu'informations de clé utilisées par l'unité d'authentification lors de l'authentification d'une clé électronique, et stocke les informations de clé d'une clé électronique secondaire de telle sorte que l'actionnement d'un appareil est temporairement autorisé. Une unité de désactivation (22, S140-S190, S210-S250) désactive des informations de clé nécessaires pour que l'unité d'authentification authentifie la clé électronique secondaire après avoir attendu que des conditions de désactivation de la clé électronique secondaire soient satisfaites lorsque la clé électronique secondaire est authentifiée par l'unité d'authentification sur la base des informations de clé stockées dans l'unité de stockage, et l'actionnement de l'appareil est autorisé au moyen de la clé d'authentification secondaire.
