Physical-Layer Security for Mixed and -Distribution Dual-Hop RF/FSO Systems

Abstract
In this correspondence, we investigate the physical-layer security of a mixed radio frequency/free space optical (RF/FSO) dual-hop communication system for both fixed and variable gain relaying schemes. More specifically, we only assume that the eavesdropping happens at the RF link because the optical link has high security. We assume that all RF channels suffer from fading, while the FSO link experiences -distributed fading. Then, we derive some analytical results for the average secrecy rate (ASR) and secrecy outage probability (SOP).
