Optical Cryptography for Cyber Secured and Stealthy Fiber-Optic Communication Transmission Academic Article uri icon


  • We propose a method for stealthy, covert, fiber-optic communication. In this method, the power of the transmitted signal is spread and lowered below the noise level both in time as well as in frequency domains which makes the signal “invisible”. The method is also efficient in jamming avoidance.
