Abstract

La présente invention concerne un procédé de contrôle d'accès pour un dispositif de communication de type machine (MTC), consistant en ce qui suit : après qu'un élément de réseau de commande de connexion de dispositif MTC a reçu une demande d'accès d'un dispositif MTC, s'il est determiné que le serveur MTC auquel le dispositif MTC souhaite se connecter est un serveur MTC qui autorise la connexion, le dispositif MTC est autorisé à se connecter au serveur MTC; et s'il est déterminé que le serveur MTC auquel le dispositif MTC souhaite se connecter est un serveur MTC qui n'autorise pas la connexion, la demande d'accès du dispositif MTC est rejetée. L'invention concerne également un système de contrôle d'accès pour un dispositif MTC. Le dispositif MTC de la présente invention ne peut se connecter qu'au serveur MTC autorisé, empêchant ainsi le dispositif MTC d'accéder à un serveur MTC inapproprié, économisant ainsi les ressources du système et améliorant également l'efficacité du serveur MTC. En outre, dans la présente invention, le processus d'accès du dispositif MTC au serveur MTC est restreint, ce qui réduit les risques d'attaque du serveur MTC, et renforce également la sécurité du système.
