The physical layer of an optical network is vulnerable to a variety of attacks, including
jamming, physical infrastructure attacks, eavesdrop**, and interception. As the demand for …

We propose and experimentally demonstrate an optical steganography method in which a
data signal is transmitted using amplified spontaneous emission (ASE) noise as a carrier …

We propose and experimentally demonstrate a method for generating and sharing a secret
key using phase fluctuations in fiber optical links. The obtained key can be readily used to …

Providing data security in the optical layer enables low latency data encryption and enlarges
the capacity for secure data transmission. As the demand for both secure and high speed …

A novel approach is proposed and experimentally demonstrated for optical steganography
transmission in WDM networks using temporal phase coded optical signals with spectral …

(57) ABSTRACT A method for providing spectral and temporal stealthy infor mation
transmitted over an optical communication channel, according to which, at the transmitting …

We propose to apply optical steganography to public differential phase-shift keying (DPSK)
transmission by transmitting a stealth amplitude-modulated signal through a DPSK link. The …

High capacity and low latency of optical connections are ideal for supporting current and
future communication services, including 5G and beyond. Although some of those services …

A temporal phase mask encryption method is proposed and experimentally demonstrated to
improve the security of the stealth channel in an optical steganography system. The stealth …

A compact and low-latency approach for optical steganography has been experimentally
demonstrated using a matched pair of chirped fibre Bragg gratings. A stealth WDM channel …
