We propose the 1-D Two-Distinct codes with two-code keying (TCK) using two mutually orthogonal states of polarizations (SOPs) in spectral components as a new code family for spectral amplitude coding (SAC) in optical code division multiple access (OCDMA) networks. Our proposed structure of the proposed codes operates the 1-D Two-Distinct codes with TCK using two mutually orthogonal SOPs in spectral components to achieve the simple architecture. The modified cross-correlation within the 1-D Two-Distinct codes with TCK facilitates the transition from one code keying (OCK) to the generation of TCK. We design the 1-D Two-Distinct codes with TCK to eliminate the multiple user interferences (MUIs) caused by other simultaneous users through modified cross-correlation, thereby improving code operation. Although the recovered bits are affected by the phase-induced intensity noise (PIIN), our proposed system can suppress the PIIN. Numerical results show that our proposed system supports up to a number of simultaneous users of 45 and provides higher data transmission rates of 2.5 Gbps compared to the other systems using 1-D SP codes with TCK, 1-D BIBD codes, and 1-D BDS codes with TCK.INDEX TERMS cross-correlation, multiuser interference, one code keying, optical code division multiple access, and two code keying.

“…OCDMA systems have been deployed in military and commercial communication systems for data transmission [1] [2]. Network security is a prime requirement in these systems due to highly sensitive information [3]. Three different security schemes are prominent to boost the security of networks, such as (i) algorithmic cryptography (ii) quantum key distribution (QKD) (iii) physical layer cryptography [4].…”

Security enhancement and bandwidth increase are requirements of ultrafast future optical code division networks that also minimise the latency at nodes without distressing the traffic performance. In OCDMA systems, eavesdropper tries to breach the optical code, and encoded/encrypted data in order to get correct code word of legitimate user. For security enhancement, an ultra high speed 4×100 Gbps two dimensional Diagonal identity matrix (2D-DIM) code and four input single output (FISO) all optical logic gate (AOLG) with private key encryption is proposed and its performance in terms of security is analyzed. Expressions for synchronous and asynchronous transmissions are derived for proposed work and it is perceived that asynchronous transmission has better security. Further performance/security analysis is carried out for different scenarios such as with/without FISO, with 1D-DIM/2D-DIM codes, using 4×1 AND gate/NOR gate in terms of correct code detection rate (CCDR), max. eye amplitude (MEA), Received Q factor, Signal to noise ratio (SNR) at different launched power levels for legitimate user and eavesdropper. Eavesdropper attacked the proposed system but due to FISO layering, private key encryption, and 2D-DIM codes, cannot get acceptable level of CCDR. To the best of author's knowledge, proposed system is ultra high speed with enhanced security and no reported studies have investigated security enhancement at this much ultra high speed.
