摘要： A method for detecting a contactless receiver in a field of an antenna of a contactless reader includes during a first ramp interval, exciting the antenna by applying a potential difference comprising a ramp between first and second values of the potential difference, and during a first plateau interval following the first ramp interval, maintaining the potential difference at the second value of the potential difference, while maintaining the potential difference at the plateau, measuring a response of the antenna, comparing the measured response and a reference response, and determining presence of a contactless receiver in the field of the antenna based at least in part on a result of the comparison.

摘要： A method for securing a wireless communication between a transmitter and a receiver includes: reception of a signal by the receiver; extraction by the receiver of at least one noise parameter of this signal received; comparison of the extracted noise parameter with at least one corresponding reference noise parameter stored in a memory in the receiver; decision on the presence or absence of a relay device between the transmitter and the receiver according to the result of this comparison; a preliminary calibration of the receiver, wherein: the receiver receives a signal resulting from a direct communication with the transmitter without intervention of a relay device, the receiver extracts at least one noise parameter from the signal received, and the receiver stores this noise parameter in the memory as a reference noise parameter characteristic of a direct communication without a relay device between the transmitter and the receiver.

摘要： A method of protection of a near-field contactless communication system against malicious attacks. The method includes exchange of information between a reader and a contactless card of duration T, measured with respect to a starting instant t0 seen from the reader, decoding of this information by the card, sending by the card a return signal temporally set with respect to an instant t′0+T, where t′0 is the starting instant as seen by the card taking into account delays in propagation or processing of signals received from the reader, detection of the return signal by the reader, determination of the temporal setting of the return signal with respect to the starting instant t0, and interruption of communication by the reader if the temporal setting of the return signal detected is not equal to the instant t0+T with a predetermined margin of error. The return signal is a pseudo-random sequence.
