Abstract Free Space Optics (FSO) is an optical communication technique which
disseminates light in free space such as air, vacuum or celestial space, to wirelessly transfer …

With the rapid advancements in wireless technology, the incorporation of unmanned aerial
vehicles (UAVs) in free space optical (FSO) communication can reap several benefits …

In this paper, we numerically study the secrecy performance of the free-space optical (FSO)
system by considering different eavesdrop** scenarios. More precisely, we considered …

In recent years, satellite communication (SatCom) systems have been widely used for
navigation, broadcasting application, disaster recovery, weather sensing, and even spying …

We propose a chaotic region-optimized probabilistic constellation sha** (CRPCS)
scheme to enhance the security and the resistance to turbulence for free-space optical …

This work is concerned with the secrecy performance of a free-space optical (FSO)
communication system over Fisher-Snedecor-distribution turbulence fading channel …

In this work, the effective secrecy throughput (EST) which explicitly captures both the
reliability and secrecy features of wiretap channels for an underwater wireless optical …

This paper explores the performance of a single input multiple output (SIMO) free space
optical (FSO) communication system using differential chaos shift keying (DCSK) with …

Although underwater wireless optical communication (UWOC) receives much interest lately,
security issues associated with it get little attention. In this work, it is the first attempt to …

We analyze theoretically optimal operation of an optical key distribution (OKD) link based on
fine intensity modulation of an optical signal transmitted over an attenuating channel to a …
