WebOptical encryption is aimed at making the data unreadable by a third party and has been extensively empolyed in optical networks. Optical steganography, on the other hand, aims at hiding the existence of optical signals from the eavesdroppers [5]–[9]. In effect, steganography differs from encryption because encryption Webcommunication, optical steganography. I. INTRODUCTION PITCAL steganography based on noise has been experimentally demonstrated to effectively hide a stealth channel in both the spectral domain and the time domain [1,2]. The stealth channel is carried by amplified spontaneous emission (ASE) noise emanating from erbium doped fiber ...
