Abstract

La présente invention concerne un dispositif électronique et un procédé de connexion pour dispositifs électroniques, permettant d'améliorer l'aptitude au fonctionnement par l'utilisation d'une configuration selon laquelle des fonctions utilisables grâce à une connexion à un réseau sont rendues explicites et sont déplacées directement. Ce dispositif électronique comporte : un moyen de communications en champ proche ; un moyen d'établissement de groupe de communications; un moyen de commande de connexion mutuelle ; un moyen de détection de services ; et un moyen de commande de démarrage. Le moyen de communications en champ proche émet un signal de recherche qui recherche des dispositifs partenaires de connexion positionnés à l'intérieur d'une zone de communications, reçoit un signal de réponse en réponse au signal de recherche, et spécifie que le partenaire de connexion est positionné à l'intérieur de la zone de communications. Lorsque le moyen de communications en champ proche a spécifié qu'un partenaire de connexion est positionné à l'intérieur de la zone de communications, le moyen d'établissement de groupe de communications établit le groupe de communications entre le dispositif électronique et le dispositif partenaire de connexion, exécute une authentification auprès du partenaire de connexion, et partage une clé partagée préparatoire par une opération appropriée d'utilisateur. Le moyen de commande de connexion mutuelle établit une adresse utilisée dans le groupe de communications vers le dispositif partenaire de connexion. Le moyen de détection de services utilise l'adresse et obtient une information concernant des services à utiliser, depuis le dispositif partenaire de connexion. Le moyen de commande de démarrage fournit un moyen de réception d'entrées capable d'émettre une instruction pour l'exécution d'une fonction correspondant à l'information de services fournie depuis le moyen de détection de services.
