Under such circumstances, functionality becomes the main focus and security takes a back seat. In recent years, free space optical (FSO) communication has gained significant importance owing to its unique features: large bandwidth, license free spectrum, high data rate, easy and quick deployability, less power, and low mass requirements. Aristotle’s model of communication is the oldest communication model, dating back to 300BC. Whether sensitive data is in transit over the physical layer (e.g., WiFi, 802.15.4 or Ethernet), networking layer (e.g, IPv6, Modbus or OPC-UA), or application layer (e.g., MQTT, CoAP or web-sockets) unsecure communication channels can be susceptible to intrusions such as man-in-the-middle attacks.
