Disclosed is a method for selecting an optimum assistance transmitter in consideration of the security of a physical layer in a wireless recognition communication system. The method for selecting an optimum assistance transmitter in consideration of the security of a physical layer in a wireless recognition communication system, including a transmission terminal including a main transmitter and a plurality of assistance transmitters and a reception terminal including an assistance receiver and a wiretapper, includes the steps of: acquiring a first SINR, a second SINR and a third SINR which are signal-to-interference-plus-noise-ratios (SINRs) of the main receiver, the wiretapper, and the assistance receiver whenever the plurality of assistance transmitters transmit data; selecting at least one assistance transmitter, which allows a ratio between the first SINR and the second SINR to be equal to or higher than a predetermined threshold, among the plurality of assistance transmitters as a selection assistance transmitter; and selecting a selection assistance transmitter having the largest third SINR among the selected selection assistance transmitters as an optimum assistance transmitter. |
