Abstract: Procedimiento para proteger una transacción comercial entre un vendedor (7) y un usuario, según el cual el usuario tiene que comunicar datos personales, como un número de tarjeta de pago, y que comporta la conexión a través de Internet (6) a un servidor informático (101) gestionado por una entidad emisora adecuada, el envío a dicho servidor (101) de un mensaje adecuado, la obtención, como respuesta a dicho mensaje, de una segunda tarjeta de pago (11) de dicha entidad emisora adecuada (101), el uso de datos de la segunda tarjeta (11), como, por ejemplo, su número (12), para efectuar la transacción, y que dicha segunda tarjeta (11) no es válida más que para un número limitado de transacciones, y que se caracteriza por el hecho de que conlleva, además, la identificación ante dicho servidor informático (101) utilizando una primera tarjeta inteligente introducida en un lector (51), a su vez conectado a un ordenador (5); por el hecho de que dicho mensaje es un certificado de autenticación y de integridad del emisor (CAI) que combina datos y una firma, la cual se obtiene a partir de un proceso de cifrado de los mencionados datos mediante un algoritmo de cifrado contenido dentro de la primera tarjeta; y por el hecho de que dicho servidor (101) utiliza este mensaje para crear dicha segunda tarjeta (11) y, en particular, su número (12).

Abstract: The invention concerns an electronic data storage medium including a body ( 30 ) made from insulated plastic material which has two main parallel sides, a semiconductor component ( 34 ) and a number of external electrical contact pads flush with the first main side ( 30 a) of the body. The body ( 30 ) includes a recess ( 32 ) opening out onto the first main side ( 30 a). The storage medium also includes a number of conducting elements ( 28 ), each with a first end (a) flush with the first main side to form an external contact pad, a second end (b) arranged in the said recess and an intermediate part (c) buried in the body; and A number of connecting elements ( 38 ) to electrically connect the terminals of the semiconductor component to the second ends of the conducting elements.

Abstract: This invention relates to an integrated circuit device comprising a memory and at least one application program residing within said memory. This invention is characterized in that the application program comprises at least one configurable variable and a list of at least one reference element, and in that said memory includes, on the one hand, at least one means for initializing said variables, wherein said means is configured with several parameters, one of which parameters is said reference element list, and on the other hand, a command for sending data that contain, in particular, values to be assigned to the configurable variables. This invention can be applied, in particular, to smart cards.

Abstract: The method involves performing an additional calculation by a verification function on an intermediate result to obtain a calculation signature. A part of the calculation is performed to recalculate the signature and compare them to detect a possible error. An elementary operation using another super-function operation is performed from a larger set. Independent claims are also included for the following: (a) an electronic assembly comprising storage unit of a calculation process (b) a computer program including program code instructions to execute the steps of securing an electronic assembly (c) a smart card comprising a storage unit of a calculation process.

Abstract: The message signature verification technique has a unit (11) storing messages. following storage, the signature and certificate are loaded to a secure unit (21). The public key is verified, and the confidence level established. The output is sent directly to a printer display (31) , and the digital words are verified (30) in the display unit. Whilst verification is taking place the secure unit calculates the algorithm keys and carries out decyphering and comparisons. Depending on the result, the message is confirmed as valid or not.
