We present different optical secure point-to-point transmission schemes using a planar multiport encoder/decoder. We consider both bit- and block-cipher cryptography: in the first case, each bit (both mark and space) from each user is encoded in a tw

TRIGONOMETRIC TRANSFORMS FOR HIGH-SPEED OPTICAL NETWORKS: ALL-OPTICAL ARCHITECTURES AND OPTICAL OFDM
Publikováno v:
Journal of Networks
In this paper, it is shown that the use of real trigonometric transforms can advantageously replace the Fourier transform in optical communication systems, for both all-optical and electronic signal processing. All-optical discrete Hartley transform

An all-optical method to enhance confidentiality in optical networks is presented. Security of a P2P OCDMA transmission is analyzed, where data are scrambled by a cascade of encoders, so that the decryption difficulty is increased.

In this paper, two different configurations to enhance the system confidentiality in a multi-user environment are presented. All-optical scrambling, based on optical code division multiple access (OCDMA) encoders, is used to prevent signal decryption

A novel optical layer solution to increase confidentiality in optical code division multiple access (OCDMA) transmission is proposed. We use two or more optical encoders/decoders to increase the degrees of freedom in the encoding process, increasing

The physical layer security of passive optical networks (PON) is investigated within a rigorous cryptoanalysis framework; we consider different threats and confidentiality attacks and propose different secure optical code division multiple access (OC
