Abstract

Lately, it has been demonstrated that free-space optical (FSO) communication systems are not interception-free. For that reason, the scientific community is paying special attention to study these links from a physical layer security point of view. In this work, some potential eavesdropping attacks are studied for multiple-input/single-output (MISO) FSO communication systems with equal gain combining (EGC) reception over gamma-gamma (GG) and misalignment fading channels. A novel asymptotic solution at high signal-to-noise-ratio (SNR) is obtained to compute the average secrecy rate over turbulence channels. The robustness of FSO technology is once again proven by employing multiple laser sources at the transmitter side and, hence increasing the secrecy rate and obtaining a performance close to the capacity with no eavesdropper.
