RF steganography based on photonics

Various examples are provided related to single channel and multi-channel radio frequency (RF) steganography. In one example, a method includes generating an amplified spontaneous emission (ASE) broadband signal; spectrally slicing the ASE broadband light to achieve taps for generating a dynamic photonic finite impulse response in an RF domain; generating a stealth-modulated broadband optical carrier by combining a stealth signal with the spectrally sliced ASE broadband light; passing the stealth-modulated broadband optical carrier to a dispersive medium to achieve the dynamic photonic FIR in the RF domain; and transmitting the stealth-modulated optical comb carrier via a transmission fiber. The ASE broadband light can have wavelength and intensity corresponding to background noise of a photonic system. In another example, a system for RF steganography includes a stealth transmitter. The stealth transmitter can generate and transmit the stealth-modulated optical comb carrier to a stealth receiver via a transmission fiber.
