Abstract:
A protected electrical device having at least one electrical sub-assembly (1) to be protected comprises on at least one (11) of upper and lower surfaces (11, 12), at least a screening layer (2) against the electromagnetic (EM) and radiofrequency (RF) fields emitted by the electrical sub-assembly (1). The screening layer (2) comprises at least a first layer made of soft magnetic material with a high relative permeability (µr) larger than 500. The screening layer (2) is placed on substantially the whole surface of said at least one (11) of the upper and lower surfaces (11, 12), except on predetermined regions (1a) of limited area, the electrical connections (8, 9) with external devices being located on at least some of the predetermined regions of limited area.

Abstract:
The invention is a system of managing indexation of memory. Said system has a microprocessor, and a flash memory. Said flash memory has an indexed area comprising indexed items, and an index that is structured in a plurality of index areas comprising a plurality of entries. Said flash memory comprises an index summary comprising a plurality of elements. Each index summary element is linked to an index area of said index. Each index summary element is built from all entries belonging to said linked index area and is built using k hash functions, with 1 ≤ k.
Abstract:
The invention relates to a personal token storing a javacard application code lying over an area of the memory of the personal token, the personal token being able to run such javacard application so as to deliver HTML page data to an external device for the external device to display an HTML page on the basis of the such delivered HTML page data, said personal token further storing data to be used as a constructing part of the HTML page, characterized in that the data to be used as a contributing part of the HTML page are in at least one file which is separate from the memory area over which the Javacard application code is lying, and the personal token is programmed for opening the at least one file storing the contributing part of the HTML page when such data are requested for delivering said HTML page data to said external device.
Abstract:
The invention relates to a communicating method between a terminal assembly comprising a terminal and a secure personal token (10, 30, 50) hosted by the terminal in a communication network and a remote entity (11,31,51) in the communication network via a SIP connection, characterized in that it comprises the step which consists in interacting with personal data stored in the terminal assembly, which are associated specifically to the end-user and which are subject to being changed during the life duration of the personal token.
Abstract:
The invention relates to an OTP token consisting of an IC card (10), in particular a smart card emulating a SIM card, and comprising an OTP application (11). The IC card relies on a communication device (20) such as a regular cellular phone, which displays the OTP generated by the IC card (10).
Abstract:
The invention relates to an authentication token (10) for a communication network comprising a microprocessor (11), a memory (12), a stored secret key (Ki) and a set of instructions for controlling the microprocessor (11) into performing an authentication calculation on the basis of a received random (RAND) and on the basis of the stored secret key, characterized in that it includes a memory location dedicated for storing a counter value and it includes instructions for making the counter value evolve each time the authentication calculation is performed.
Abstract:
A system and method for establishing uniqueness in type definition names. Each application vendor has associated therewith a unique data sequence. The data sequence is combined (510,520) with the type definition name and then a digital operation is performed (530) to produce a unique digital identifier that is used in place of the type name.
Abstract:
The invention relates to a personal token (15) for access to a telecommunication network, such as a SIM card, said personal token (15) storing an entity which is able to deliver to a rendering device (10) associated with said token a rights objects, said rights object comprising at least a decryption key and at least a usage right for the digital content
