Abstract: The invention concerns a method enabling a personal computer (1) to be authenticated by a server (2). The method comprises the step, which consists for the user in launching the execution of a log-on procedure software, by introducing personal identifiers (21) providing access to a signature private key (14) for long-term use relative to the duration of the session. The log-on procedure software produces: identification data of the session Id, a public ephemeral module n (9), a public exponent v and at least a pair of ephemeral public numbers G (11) and ephemeral private numbers Q (12) related by a generic equation of the type: GQ (mod n) or GxQ 1 (mod n), an ephemeral certificate (13) linking, by means of said signature private key (14), Id (8) and n (9). The public ephemeral module n (9) is of reduced size relative to the signature private key (14). The method comprises the step which consists for said user (5) to launch the execution of an evidence software, the step which consists for the server (2) in launching the execution of a control software.

Abstract: A digital broadcasting process, suitable for digital audiobroadcast, comprises encoding the data in the form of binary words using a redundant code to obtain a sequence of modulation symbols and transmitting the symbols in a plurality of subchannels at different frequencies. The symbols are time interlaced with such a distribution that two adjacent symbols cannot be transmitted in time succession and at the same one of the frequencies. Preferably, a Viterbi decoder is used. Particular constructions of an emitter and a receiver are also described.

Abstract: Data communication between a processing unit (UT) and external means may take place via a plurality of data streams (FXE1, FXE2, FXS1, FXS2). Means (GESi) check the mutual consistency of said streams and report and correct abnormalities. This self-synchronisation is achieved by inserting separators into the data streams to separate the data, and by means of a freezing mechanism (GL, FC) for freezing the internal operation of the processing unit.
