A device for communicating with other devices to allow them to access applications, comprises: at least a first application; authentication means for authenticating a communicating device; and access control means accessible by a communicating device requesting access to the first application without the communicating device having been authenticated by the authentication means. The device is further arranged to arbitrate whether access of the communicating device to the first application is granted or refused wherein if the arbitration requires an authentication of the communicating device, the access control means instructs the authentication means to authenticate the communicating device.

Security architecture

The present invention relates to communication system comprising first and second communication devices () each capable of communicating with a telecommunications network (), and both being connectable to each other by a data link () for information transfer and to a method for operating the same. The first communication device () contains individual information, and the second communication device () comprises a special memory area () for storing individual information acquired from the first communication device (). To enable an improved and facilitated usage of the system comparator means () for comparing the individual information contained in the first communication device () with that stored in the special memory area () of the second communication () device are provided. Therefore, only changes of the individual information of the first communication device () are stored in the second communication device () after comparing the individual information from the first communication device () stored in the second communication device () with the individual information in the first communication device () when the first communication device () is connected again to the second communication device ().
