    Abstract: PROBLEM TO BE SOLVED: To provide a method and a system to achieve authentication of an electronic tag by a host to be connected to the tag through a reader.
    SOLUTION: At the tag side, a first digital signature is calculated by using at least one first function shared by the tag and the reader and by considering at least one first secret key recognized only by the tag and the reader, and the first signature is transmitted to the reader. At the reader side, a second digital signature is calculated by using at least one second function shared by the reader and the host which are different from the first function and by considering the first signature, and the second signature is transmitted to the host. At the host side, identity of the second signature, the second function and the host to a confirmed value calculated from a second secret key shared by the tag and a single element selected from the reader is checked.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for transmitting data between a master modem and at least one slave modem of a master-slave network in orthogonal frequency-division multiplexing communication. SOLUTION: The method assigns to each slave modem at least one transmit frequency band and at least one receive frequency band chosen in a range of frequencies capable of being processed by the master modem. Each slave modem applies oversampling or undersampling to a transmit or receive signal. A band-pass filter corresponding to the assigned frequency band filters downstream of the oversampling or upstream of the undersampling.
