| Abstract(in English) | Physical layer security (PLS) is the transmission control for suppressing the received power of un-desired node under the certain level. Since the undesired node cannot decode the information without bit error, the secure communication link can be constructed. Moreover, physical layer network coding (PLNC) is one of the efficient relay transmission methods. In PLNC, two or more nodes transmit the signal to the relay node, simultaneously, and then the relay node transmits the compounded signal to each node. At each node, a desired signal can be acquired by removing a known signal from a relayed signal. From the PLS s point of view, each transmitted signal becomes the role of mask for hiding the other transmitted signal. Therefore, it is difficult for the relay node to decode the information of each node, separately. The secure relay communication even with un-authorized relay is constructed, where the unauthorized relay is referred to as untrusted relay. This paper estimates the secure capacity of PLNC and consider the transmit power control for enlarging the secure capacity. |
