A Comprehensive Review on Security in Free-Space Optical Communication

Abstract: Free Space Optical (FSO) Communication is an optical communication technology that uses laser beams to wirelessly transmit data over free space. It is a prominent and essential technology in wireless communication. It is an in-demand technology for wireless communication as it has high data rate transmission capacity, high bandwidth, low latency, and lower power consumption. FSO Communication is very advantageous in regards to security in the communication technology. Even then issues with respect to security persists as there is advancement in different technologies. FSO systems are still vulnerable to eavesdropping, jamming and physical layer attacks as it utilizes open Line of Sight (LoS) communication. Several extensive studies have been conducted to improve the security measures in FSO Communication. This review studies the current scenarios in security of FSO communication. This paper reviews several work conducted on security in FSO aims to provide a comprehensive review of existing security strategies, compare their effectiveness, and highlight key research gaps that need to be addressed for future developments in secure FSO communication.
