| Abstract(in English) | 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. So far, the authors have evaluated the amount of information that relay station can exploit in secret by the CSI impersonation. However, the method of disguised CSI for maximizing the information leaked to the untrusted relay has not been clarified, yet. This paper considers that the CSI impersonation is constructed by the linear programing problem for maximizing the leaked information to the untrusted relay. Prom the numerical results, if it is the constrained condition for the impersonation of CSI that the stochastic model of CSI is perfectly matched to the channel model, such as Rayleigh fading, the information leaked to the untrusted relay can be reduced. |
