    Abstract: The digital contents rights management system has detection of passing time conditions (CONDtj) from an application (APPLi) whilst a processor (2) is operating. There is a time element (7) sorting in crossing order the expiry time, and a register (3) storing the condition nearest the current date. A comparator (4) provides the register expiry with respect to the current system date.

    Abstract: The method involves producing an authentication code comprising authentication byte from transmitted data. Data and a signature comprising the authentication byte of authentication code are emitted. An acknowledgement receipt is received, and authentication of the receipt is verified, where length of the code is higher than that of the signature, and the authentication code comprising hidden bits is not inserted in the signature. Authentication of the acknowledgement request is determined by verifying that which of the hidden authentication byte is found in the acknowledgement request. Independent claims are also included for the following: (1) a method for receiving data (2) a data transmitting device, comprising a communication and data processing unit (3) a data receiving device, comprising a communication and data processing unit.

    Abstract: L'invention concerne un procédé de transmission de données entre un premier (D2) et un second point (M2), comprenant les étapes consistant à transmettre, du premier point vers le second, des données (MESS) accompagnées d'une signature (S1) comprenant des bits d'un premier code d'authentification (CA), et transmettre, du second point vers le premier, un accusé de réception (ACK). Selon l'invention, la longueur du premier code d'authentification (CA) est supérieure à la longueur de la signature (S1) et le premier code d'authentification comprend des bits d'authentification cachés. L'accusé de réception (ACK) est produit en utilisant des bits d'authentification cachés d'un second code d'authentification (CA') présumé identique au premier, produit au second point.

    Abstract: A method of automatic calculation of several integer divisions by a same integer divider, of several successive integer dividends, separated from one another by a constant iteration step, smaller than or equal to the divider, including selecting, from a table of increments, according to an iteration index, a 0 or a 1 to be added to the operation result of the preceding iteration, the number of 0s in the table of increments being equal to the divider minus 1.
