Abstract: A user system includes terminal equipment, a removable integrated circuit card and a removable memory card configured to cooperate with the terminal equipment, a card link application provided in the integrated circuit card to establish and manage a secure logical connection between the integrated circuit card and the memory card through the terminal equipment, and an application programming interface provided in the terminal equipment to receive and execute commands from the card link application and to cooperate with the card link application to establish the secure logical connection between the integrated circuit card and the memory card through the first terminal equipment.

Abstract: A user system includes terminal equipment configured to receive and send data through a communication network; a terminal security support system removably insertable in, and configured to cooperate with, the terminal equipment; and a trusted user platform for the terminal equipment. The trusted user platform includes an information protection system configured to implement security functionalities, configuration instances for the information protection system, and a trusted communication agent configured to provide a safe communication between the terminal security support system and a remote management centre through the terminal equipment to allow the information protection system to be remotely configured from the remote management centre.

Abstract: A method is provided which allows a service to be enjoyed through a mobile telephone terminal without the need of paying for this service. This can be achieved by allowing a first subscriber to use the credit or subscription of a second subscriber. The subscriber identification cards at least of the two subscribers involved are provided with short range radio communication transceivers and establish a short range communication channel between them so that one card may request the other card to pay for this service and the other card may grant this request through this channel. Then the mobile telephone networks of the cards are informed of the granted request. Before, during and after the grant of the request, the subscriber identification cards remain active and operative in communicating together and with the associated terminals.
