Abstract: A method wherein at least one service of an application stored in a microcontroller card is communicated to a terminal. The terminal transmits a command identifying the selected application to the card immediately after selecting the application. In order to reduce in the card the time for accessing the application service data by the terminal, a reply generator in the card selects the active services related to the application in the card in response to the command, and dynamically establishes a list of data identifying these services, to transmit a reply message including the identification data from the card to the terminal. A reply analyzer in the terminal analyzes the identification data of the reply message to communicate the at least one service of the application identified by the identification data.

Abstract: A method for encrypting/decrypting a message includes the initial step of generating keys by the sub-steps of generating a public key; generating a decryption key; and generating a derivation key. For a first entity, the message is encrypted using the public key and a cipher. For a second entity, the cipher is decrypted to find the message. A trapdoor associated with said message is generated. The trapdoor corresponds to a derivative of the derivation key specific to the message. A test cipher is tested, using the trapdoor associated with the message, to determine if the test cipher is an encryption of the message using the public key.

Abstract: Two service signals are transmitted from a service server through a first network in such a way that users' terminal devices display personalized service data items. When service signals are filtered, a terminal device extracts common data items accessible for several terminal devices and a parameter type from a service signal identified by a stored identifier. An end address is determined by applying a stored parameter, related to the parameter type, to a pre-recorded or transmitted algorithm. The end address is transmitted, through a second network, to a server which transmits a first personalized file associated with the end address and bearing personalized data items displayed with the common data items in the device.

Abstract: The invention concerns a terminal (T) comprising an agent (AS) for processing a secure content encrypted with a key (KCN) and transmitted by a first server (SCN). In order to manage a secure access to the secure content, an application (AG) of a portable communicating object, such as a chip card, associated with a terminal stores one type of related digital right (TDN) and a certificate and transmitted by the agent and stores an access right (DA) and the key (KCN) related to the secure content transmitted from a second server (SAD). The application adapts the access right and the key and modifies the secure content, based on the type of right, and produces a secure access file based on the adapted access right and the key and on the certificate, the produced file being accessible by the terminal so that the agent may process the modified content.

Abstract: The invention relates to the reuse of identity data from an identity module in a user equipment by a peripheral device. In order to enable the reuse of identity data from an identity module, such as a SIM or UICC card, in a user equipment by a peripheral device, the identifier of the peripheral device is transmitted to the module upon establishment of communication and authentication between the module and the peripheral device. Subsequently, identity data are transmitted, preferably selectively, by the identity module to the peripheral device when the transmitted identifier is recognized as one of the identifiers of the peripheral devices that were previously stored in the identity module. The identity data are reused by the peripheral device in order to establish a communication with the home network of the user equipment or with a local wireless network.

Abstract: A chip card needs to be allocated in a secured manner to a network operator via a personalization center in order to determine a final authentication key which is attributed to a subscriber of the operator without its being transmitted via a network. The following is loaded into a card by a module: an algorithm and an allocation key; an algorithm for determination of the authentication key and at least one intermediate authentication key. A module transmits an allocation message which includes a final identity number, a random number and an allocation signature from the center to the card. The card authenticates the message by means of the allocation algorithm as a function of the allocation key and the allocation signature, and determines the final authentication key as a function of the intermediate key and the random number.
