ABSTRACT
Amplified spontaneous emission (ASE) light is the most natural optical carrier to hide a message in the existing optical networks at photonic layer. To enhance the anti-intercept ability of the ASE-carried stealth channel, a novel optical stealth communication scheme based on quantum noise stream cipher is proposed. The ASE light is intensity modulated by the cipher-text according to Y-00 protocol, and then transmitted under public optical noise after power attenuation. The expression of quantum noise stream ciphered ASE signal is derived, and numerical simulation is carried out. A proof-of-concept experiment is set up to demonstrate the feasibility of the proposed scheme. The experiment results show that the quantum noise stream ciphered stealth signals can be transmitted over a 25 km single-mode fiber span error-free.
