Abstract
In this article, we suggest enhancing the physical layer security of wireless systems using reconfigurable intelligent surfaces (RIS). We compute the secrecy outage probability and the strictly positive secrecy capacity when the source S harvests power using \(n_r\) antennas and the signal of node N. The harvested power is used to broadcast a signal to the destination D that is also received by the eavesdropper E. The broadcasted signal by S is reflected by RIS so that all reflections have a zero phase at D. We also add RIS between N and S to increase the harvested power.
