Abstract: Services are distributed via a distribution network to terminal devices. One of the services is an electronic service guide stored in the terminal devices and providing descriptive data on the distributed services. To control access to the services distributed to a terminal device, the device includes a module for filtering descriptive data on the distributed services in accordance with at least one filtering criterion, and a graphics module for displaying the filtered descriptive data that meets the filtering criterion so as to enable services associated with the displayed filtered descriptive data to be selected.

Abstract: A method of producing a smart card having a reduced format in relation to a second standard format and an adapter with the second format, which is associated with the smart card. A card body has a zone for the extraction of the smart card and a zone for the extraction of the adapter. At least the smart card is extracted from the support. The smart card is extracted from a zone located outside the peripheral outline of the adapter extraction zone. The invention also relates to the support thus obtained.

Abstract: A method for securing the execution of a session with a data processor, such as a smart card, under the control of at least two entities, such as servers. Session numbers and session keys are transmitted to the entities. The session number and key are applied to an algorithm in the data processor and the respective entity to produce a result and signature. The results and the signatures are transmitted to the data processor. A session corresponding to the results from the data processor is executed when the signatures are identical to the results. In another embodiment, one of the entities receives a delegation of a third entity to authorize execution of the session.

Abstract: Access rights lists, such as capacity or access control lists, are dynamically managed in a data processing element such as a smart card from an administrator server. To access an access rights list from the server, the list is signed in the server so that a signature can be transmitted to the card. The card compares the signature received from the server to signatures determined according to the access rights lists contained in the card and keys associated with those lists. Server access to an identified list is only authorized when it corresponds to a signature which is found among the determined signatures in the card and which is identical to the received signature.

Abstract: A method and associated device for checking a biometric signature by a simple and secure calculation adapted to personal objects of the chip card type. The method is based on the storage within the object of an obscured biometric signature and an associated authentication code. A terminal capturing a fingerprint compares the fingerprint data with the obscured biometric signature transmitted by the card and transfers the result of this comparison to the chip card, which validates this result with the authentication code.

Abstract: A table establishes correspondence between first sets of at least one number, expressed in accordance with a signed code where each number may have the value of 0, 1 or ?1, and second sets of at least one number, expressed according to a simple form where each number may have the value 0 or 1. An input sequence of numbers is decomposed into sets of numbers present in the correspondence table. For each set of numbers derived from the decomposition, a corresponding set of numbers is given by the correspondence table. A sequence of numbers is compiled from the sets retrieved from the table. The invention is in particular useful in various algorithms, such as in cryptography, for example to store values in signed binary mode, in compact non-adjacent form with only the numbers 0, 1 and/or for rapidly producing random numbers in the non-adjacent form.

Abstract: Access control to data processing means, such as a smart card, is made secure by simulating a comparison block by block of part of a secret code with part of a presented code through a block-by-block comparison of part of the presented code and part of a determined number when the presented code is found to be erroneous. Each time the card is used, a constant number of operations are applied to the presented code and at least for part of the secret code, and at most for a complementary part to the determined number, thus avoiding different signatures of power consumption for different presented codes.

Abstract: A method for dynamically authenticating an executable program, that is the continuation of the instructions defined thereby, is performed repeatedly during the very execution of the program. The method for making secure an electronic portable object through execution of a program supplied by another insecure electronic object uses, inter alia, a secret key protocol.

Abstract: The invention concerns a method for activating unlocking of a mobile terminal (TM) to be connected to a radio communication network (RR) and co-operating with a smart card (CP), wherein an unlocking activating indicator stored in a first state in the card is periodically read by an application of the terminal to maintain the terminal locked if the indicator is in the first state. A server (SO) transmits an updating message including a state-changing command to the card via the terminal after a predetermined usage time interval so that an application in the card shifts the unlocking activating indicator into a second state. If the unlocking activating indicator is read in the second state by the terminal application, the latter commands the unlocking of the mobile terminal.

Abstract: In order to request the presentation of an operator indicator in a user's terminal having a first mobile terminal connected to a first cellular radiocommunications network, the operator is related to a second mobile terminal whose call number is stored in the user's terminal and is transmitted therefrom to a server of the first network. The server compares the transmitted call number with call numbers of the first network mobile terminal contained in a first list, in such a way that it is enabled to read the operator indicator corresponding to the transmitted call number. A module in the form of a UICC card stores the indicator and submits it to the user for informing the user whether the call number belongs to the first network or belongs to another network.

Abstract: A mini card has a size smaller than a card that conforms to established standards, and includes a hole for attachment to a key ring or other external device. Increased durability is provided by means of a substrate that includes a core made of PVC material, sandwiched between two durable layers of polyester material. Printing on these layers is protected by transparent overlay layers made of PVC. The durability of the card is measured by means of a test procedure in which random multi-dimensional motion is imparted to an assembly of the card and an attached weight. The durability is quantitatively indicated by the amount of elapsed time until the weight becomes separated from the card while undergoing the vibrational movement.

Abstract: A smart card that is compatible with the USB protocol and may be compatible with multiple different protocols includes a standard set of contacts that comply with the protocols of a published standard. Another contact, not designated by the standard, may be added and used to indicate whether the card is to operate in one of a number of protocol modes. When the card is to operate in the USB mode, a simple start-up procedure is employed which does not require strict timing constraints, enabling a less expensive interface device to be used. The interface device can be connected to any bus of a computer which operates in accordance with a desired protocol. Due to the flexibility and functionality offered by smart cards that have microprocessors incorporated therein, the multi-protocol smart card can be used to drive, or otherwise communicate with, any of a variety of peripheral devices, whether or not a personal computer is present in the system.
