Abstract: The method of protecting a secret key from being read by a non-secure software application, comprises a step (94) of recording the secret key as a routine stored in an executable-only memory. The routine having: load instructions to load the secret key into a memory readable by a secure and a non-secure software application, if the routine is called by the secure software application, and control instructions to leave only dummy data instead of the secret key in the readable memory if the software application calling the executable-only routine is the non-secure software application.

Abstract: A semiconductor device having circuitry comprising an embedded memory, an embedded processor for executing application codes, and a functional hardware element coupled with the embedded memory via a protected bus, and with the embedded processor via an unprotected bus, the hardware element being arranged to protect the protected bus, and including a locking means comprising at least one lock bit for globally locking at least part of the locking means before executing the application code.

Abstract: The radio telecommunication terminal (2) comprises a data burst scheduler able to schedule the continuous transmission of consecutive data bursts which generate noise of similar energy on the radio-frequency channel as long as a specific radio-frequency channel is used to receive a radio signal, the respective energy of the noise generated by the transmission of two consecutive first and second data burst being similar only if the noise energy gradient between the end of the transmission of the first data burst and the beginning of the transmission of the second data burst is situated between predetermined upper and lower limits.

Abstract: The element (1) comprises a securing portion (5) having a U-shaped section and a flexible tubular cushion seal (6) connected to the securing portion with a connecting strip (9) that is offset in relation to the axis of the neutral bending fiber along a curve in a globally perpendicular direction to the lateral side of the shaped element. When there is a curve in such a direction, the cushion tilts toward the securing portion instead of deforming, thereby eliminating the appearance of unattractive creases and limiting crushing at the top of the element. Preferably, the connecting strip is inclined at an angle that facilitates tilting by the cushion seal and comprises a hinged area (23) of reduced thickness. The securing portion may comprise a raised contact area (24) which the cushion seal abuts after tilting. This invention is of interest to manufacturers of elements and automobile manufacturers.

Abstract: The invention relates to a device for decoding encoded digital signals of the MPEG-type, comprising different modules (M1, M2, M3, . . . ), provided for communicating with an external random-access memory via an arbiter (ARB) intended to control the different types of access. Storage in the memory and the method of addressing are such that the decoding operation may not only be carried out with a conventional memory (DRAM) but also with synchronous DRAM memories (SDRAM), in which the arbiter uses the same mode of communication in each case and the other modules remain unchanged.
