    Abstract: L'invention concerne un procédé et un circuit de détection d'une éventuelle perte de caractère équiprobable d'un premier flux de bits de sortie (NBS1) issu d'au moins un premier élément de normalisation (3) d'un flux de bits initial (BS), consistant à soumettre le flux initial à au moins un deuxième élément de normalisation (4) de nature différente du premier, apparier (8), bit à bit, les flux issus des deux éléments, et vérifier (5, 9) l'équirépartition des paires d'états différents.

    Abstract: The functional processes are divided into steps such that each process is interrupted with the storage of intermediary result, at the end. The steps of consecutive processes are executed successively and the process of next step is selected according to the result of random drawing of a number. An independent claim is also included for processor for executing identical functional processes.

    Abstract: The process involves starting an execution of a calculation, and starting another execution of the same calculation once the former execution has freed a block and its process in a second. The executions are synchronized such that the latter execution uses a hardware block only when the former execution passes to the next block. The identity between the two results is verified at the end of execution of both the calculations. An independent claim is also included for a chip card.

    Abstract: The secured data transfer operates within a programmable circuit containing a processor, controller (UC), ROM and RAM, with a data bus (DBUS) connecting the memories. N octets of secret data are transferred over the data bus, and the octets are sent in a different order each time the data transfer is made, under control of a random number generator (GA).

    Abstract: The secure data transfer operates in a programmable circuit containing a controller (UC), ROM and RAM, connected by a data bus (DBUS). N octets of secret data are transferred over the data bus, and the octets are sent in a different order each time the data transfer is made, using a transfer rule that has a parameter chosen at random before each transfer, using a random number generator (GA).
