This novel study uses structured light beams to enhance security and camouflage in free-space optical (FSO) communication systems. The system employs Bessel, Airy, and Vortex beams due to their properties, such as their unique shapes, adaptability to changing environmental conditions, and spread over long distances while keeping data portable. The structured light beams are dynamically switched during transmission to integrity and security over varying propagation distances and atmospheric conditions. In weak and moderate weather conditions, all three structured light beams can propagate up to 5 km while preserving data integrity. However, under stronger turbulence, the Bessel and Vortex beams can extend beyond 3 km, whereas the Airy beam is limited to a maximum distance of 2 km. The system multi-layered security approach includes beam shaping and selective switching between structured light beams to provide camouflage and enhance data protection, ensuring secure and reliable optical communication even in challenging environments. Simulations using the OptiSystem 18 program demonstrate the system robustness and effectiveness in a high-speed FSO communication.
