    CPC classification number: G06K7/0008

    Abstract: The invention concerns a terminal generating a high-frequency electromagnetic field by means of an oscillating circuit, adapted to co-operate with at least a transponder when the latter enters said field, comprising means (37) for regulating the phase of the signal in the oscillating circuit with respect to a reference value, and means for detecting, on the basis of a current measurement in the oscillating circuit and a voltage measurement at the terminals of a capacitive element (31) of said oscillating circuit, an electric signature of a transponder.

    Abstract: The invention relates to an electromagnetic transponder (20) comprising: a parallel oscillatory circuit (L2, C2) for extracting a supply signal from a radiated field; a plurality of legs which are arranged in parallel on the oscillatory circuit and respectively comprise a programmable resistance (Rpi) and an interrupter (Mi); and a cyclic control element (27) for successively closing the interrupters. Each resistance embodies an element for storing part of the code stored in the transponder.

    Abstract: The invention relates to a method of supplying a private quantity (s) in an integrated circuit involved in an authentication procedure by means of an external device that takes said private quantity into account. In order to verify the integrity of said memory element, the private quantity is a function of a signature (SIGN) of at least one memory element (4, 10, 11, 12) associated with the integrated circuit.
