“…As such, optical OFDM multiple access (OFDMA) PONs are expected to play a crucial role in future converged networks, as they can offer a number of well-documented salient advantages including high spectral efficiency, adaptive signal modulation according to channel characteristics, dynamic bandwidth allocation (DBA) with fine bandwidth granularity, trivial equalization through simple complex multiplication per subcarrier, as well as excellent tolerance to chromatic dispersion. For the network convergence, studies have shown that OFDMA PONs can provide high-capacity and long-reach operation [10][11][12][13][14]. Moreover, their performances can be further improved by non-optical carrier single-sideband [15], and their physical-layer security enhancement is also achievable when use is made of chaotic constellation transformation and pilot-aided secure key agreement [16] or three-dimension Brownian motion and chaos in cell [17].…”

“…Fig. 12 plots the BER curves of our proposed scheme with DNA encoding encryption and spiral scrambling and the scheme only with DNA encoding encryption by simulation [31]. According to the figure, the proposed scheme exhibits superior BER performance by approximately 1 dB compared to the previous method at the BER of 10 −3 .…”

“…A type of bit-level encryption, i.e., deoxyribonucleic acid (DNA) encoding encryption [30], can improve physical-layer security. Since DNA has the characteristics of a satisfactory amount of storage, massive parallel processing capabilities, and ultra-low power consumption, the combination of chaos and DNA encoding encryption is proposed in OFDM-PON system [31]. However, only a few combination researches have been conducted on combining DNA encoding encryption and chaos in OFDM-PON.…”

This paper proposes a novel hybrid secure method based on improved deoxyribonucleic acid (DNA) encoding encryption and spiral scrambling in chaotic OFDM-PON for enhancing the physical-layer security. In the improved DNA encoding encryption, the oddeven cross-bit DNA encoding, base scrambling and base-level substitution are determined by chaotic sequences. For each binary and base, the selected encoding rules and base scrambling methods are dynamically changing, which enhances the robustness against malicious attacks by attackers. In the spiral scrambling process, the QAM symbol matrix is divided into several blocks, and these blocks are scrambled. In the scrambling of the plural matrix, the position where the spiral starts and the orientation and direction of the traversal are also controlled by the chaotic sequences. By employing DNA encoding encryption and spiral scrambling, a key space of ∼ 10 135 can be achieved in the multi-fold encryption of the proposed scheme, which can improve the physical-layer security. The encrypted 16-QAM OFDM data are successfully transmitted over a 60-km SSMF in OFDM-PON. The simulation results demonstrate that it has better BER performance at the BER of 10 −3 than other schemes. The proposed encryption method can effectively protect data from attacks by eavesdroppers or illegal users.

“…In [19], an optimum block dividing scheme combined with two-dimensional adjusted logistic sine map and dynamic key assignment technique is employed for further security improvement in OFDM-PON. Security enhancement for OFDM-PON using three-dimensional Brownian motion and chaos in cell [20] and also using chaos encryption and DNA encoding [21] are demonstrated.…”

Securing transmission of information between legitimate transmitter and receiver sides is a great challenge for mathematicians, computer scientists and engineers in recent years. This paper aims at achieving three goals. The first of them is to introduce a novel fractional order two dimensional (2D) map having very complex chaotic behavior and distinct large positive values of Lyapunov exponents over wide range of parameters, compared with other 2D maps in literature. Secondly, a new reliable secure encryption scheme combining the associated chaotic pseudo-orbits of the proposed map with the advantages of elliptic curves in public key cryptography is suggested, for first time, and applied to colored images. The hybrid scheme is capable to confirm reliable secret keys exchange in addition to highly obscure and hide transmitted information messages. Finally, a thorough mathematical analysis of security performance and evaluation of encryption scheme immunity against all possible attacks are carried out and proved its efficiency and robustness. INDEX TERMS Chaos-based cryptography, chaotic maps, discrete fractional calculus, elliptic curves, pseudo-orbits.
