In this paper, we investigate the physical layer security of a wireless communication with a reconfigurable intelligent surface (RIS) and a full-duplex (FD) legitimate receiver over Rayleigh fading channel in the presence of an eavesdropper. In addition, we examine the scenario where the FD receiver is sending a jamming signal while receiving the required message to confuse the eavesdropper. We derive closed form expressions of the intercept probability of two scenarios with and without jamming signal and we also use the strictly positive secrecy capacity (SPSC) metric to gain more insight on the security of our proposed system. To illustrate the analytical analysis, numerical results are provided under different network parameters to study the effect of RIS and jamming technique on the security of FD receiver. © 2021 IEEE
