摘要： The invention relates to contactless communication systems between a moving object and a reader, in particular systems in which the moving object is a chip card or an identification tag. To enhance communication security, the card reader transmits, from a radiofrequency transmission antenna separate from the main communication antenna, a disturbance signal having the same frequency and modulation type characteristics as the response signal expected from the card to the reader; the electromagnetic coupling between this separate antenna and the antenna of the reader is, however, such that the latter does not “see” the transmitted disturbance but detects only the response from the card; on the other hand, the environment between the card and the reader sees the response from the card only mixed with the disturbance signal.

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.
