Access Decision based on Secure Capacity for prevention to CSI Impersonation of Untrusted Relay
Ryota Sugimoto, Osamu Takyu · 2019
A physical layer network coding is a highly efficient data exchanging scheme between two nodes through a relay. However, if the untrusted relay is assumed, it impersonates the channel state information (CSI) for exploiting the data through relay. This paper pays attention to the protocol of CSI impersonation and proposes the wireless access decision based on secure capacity. The computer simulation shows the proposed access decision suppresses the exploitation of data through relay as well as increases the secure capacity against the untrusted relay.
