Popis
Shrnutí:	In Physical Layer Network Coding (PLNC), the two information sources access to the relay station, simultaneously and thus the transmitted signals are combined, together. Since the relay station hardly decodes each information single, the security for avoiding the information leak to the relay station is maintained. Therefore, the PLNC is attracting much attention in terms of physical layer security (PLS). However, the information source needs the transmit power control based on the channel state information (CSI). If the relay station is untrusted, it camouflages the real CSI for stealing the information. This paper considers the camouflaging of CSI is modeled as the liner programming problem in the subject to the statistic of CSI following the model of propagation. We clarify the maximal capacity of tapping by the relay station.
