WebOptical steganography has been experimentally demonstrated using a matched pair of chirped fiber Bragg gratings. The stealth channel is temporally and spectrally hidden underneath the public channel. The public channel power penalty is < 1dB. © 2009 Optical Society of America PDF Article Previous Article Next Article WebThe threat and defend model of optical steganography based on amplified spontaneous emission noise is experimentally demonstrated. Although the optical delays in a steganography system generate large key space to hide and recover the stealth signals, delays in interferometer introduce spectral fringes that can be identified by the coherent …
Optical steganography for data hiding in optical networks …
WebPhase mask encryption is proposed to improve the transmission privacy of an optical steganography system. The stealth signal carried by amplified spontaneous emission noise is encrypted by a fast changing code. WebOptical steganography, on the other hand, provides a way to hide private data within the existing public channel so no one, apart from the intended recipient, knows the existence of the message [4]. Transmitting such private data is called a “stealth channel.” Without knowing information about the encryption process in the stealth channel, cytoreason series a
