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

It will be revealed that a myth of deploying low bit-rate uplink fiber-to-the-home (FTTH)
services while providing a high bit-rate downlink is wrong. Therefore, for the future …

Although several books cover the coding theory of wireless communications and the
hardware technologies and coding techniques of optical CDMA, no book has been …

A novel ring-resonator-based integrated photonic chip with ultrafine frequency resolution,
providing programmable, stable, and accurate optical-phase control is demonstrated. The …

Introduction: Optical code-division multiple-access (OCDMA) is receiving increasing
attention with several groups pushing to realise $ Gbit/s multi-user demonstrations [1–8] …

In this paper, we present a new algorithm to generate two-dimensional (2D) permutation
vectors'(PV) code for incoherent optical code division multiple access (OCDMA) system to …

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

In this paper, two vulnerabilities that allow an eavesdropper to extract data from an isolated
user in a two-code-keying spectrally phase-coded optical-code-division-multiple-access (O …

This paper demonstrates a high-performance optical-code-division-multiple-access (O-
CDMA) network testbed using the spectral phase encoded time spreading (SPECTS) …

The Encyclopedia of Image Processing presents a vast collection of well-written articles
covering image processing fundamentals (eg color theory, fuzzy sets, cryptography) and …
