“…Increasing the number of possible parameter values (i.e., key space) for establishing the chaos synchronization can also improve the security, as reported by Yi et al [50] and Wang et al [51]. Except for improving the security from the hardware point of view, the legitimate users can also use the independent and random private keys to switch the synchronization states to increase the difficulty of the eavesdropper in achieving the synchronization, as demonstrated by Uchida et al [20] and Jiang et al [25]. At last, we examined the statistical randomness of the two correlated random bit streams by using the NIST and Diehard test suites.…”

We experimentally demonstrate high-speed correlated random bit generation in real time using synchronized chaotic lasers commonly driven by a laser with dispersive feedback. The dispersive feedback from a chirped fiber Bragg grating induces frequency-dependent feedback delay and thus no longer causes time-delay signature, and resultantly ensures the signal randomness and security of chaotic laser. Driven by the time-delay signature-free chaotic signal, the two response lasers are routed into chaotic states and establish a synchronization with correlation beyond 0.97 while they maintain a low correlation level with the drive signal. Through quantizing the synchronized laser chaos with a one-bit differential comparator, real-time 2.5-Gb/s correlated random bits with verified randomness are experimentally obtained with a bit error ratio of 0.07. Combining with a robust sampling method, the BER could be further decreased to 1×10 −4 corresponding to an effective generation rate of 1.7 Gb/s. Bit error analysis indicates that the bit error ratio between the responses is lower than that between the drive and responses over a wide parameter region due to the synchronization superiority of the responses over the drive.

“…These methods can be divided into two categories. One is the chaotic feedback laser such as secure key distribution [9], laser exclusive or (XOR) operation [10] and delay signature-suppressed in semiconductor lasers [11], and the typical application in chaotic feedback laser and microwave photonic chaotic communication [12], [13]. These methods require two sets of chaos generation equipment to be as identical as possible, which are difficult to achieve chaos synchronization for all the modulation parameters.…”

In the paper, a deoxyribonucleic acid (DNA) extension code with 3-bit binary streams is proposed to encrypt the downlink data for orthogonal frequency division multiplexing passive optical network (OFDM-PON). It has 8 bases to make up 4 pairs of complementary codes. And it can obtain 384 matching rules, which greatly improves the randomness of matching. Here, two DNA addition operation rules are also proposed to encrypt the data. DNA extension rules can reduce half coding operations. Three 1-dimensional (1-D) chaotic systems are used to encrypt the code and control the rules. The encryption method based on the uplink streams from optical network units (ONUs) makes the security of downlink signals not just depending on the security of chaotic systems. Finally, a 22.06 Gb/s DNA extension code encryption signal is transmitted through a back-to-back (BTB) system and a 25-km standard single-mode fiber (SSMF). The proposed method not only improves the security but also reduces the computational complexity. The experimental results show that the proposed method has the ability to resist optical channel response and fiber nonlinearity, which is a promising candidate for solving the security enhancement in access networks.INDEX TERMS DNA extension code, OFDM-PON, uplink stream, 1-D chaotic system, security enhancement.

“…Owing to this, the fractional-order discrete chaotic system has become a new hot topic [ 8 , 9 , 10 , 11 , 12 , 13 , 14 ], especially for its synchronization [ 11 , 12 , 13 , 14 ]. Chaos synchronization has great significance in secure communication [ 15 , 16 , 17 ], and it plays an important role in nonlinear science [ 18 , 19 , 20 , 21 ]. Up to now, existing chaos synchronization methods for fractional-order discrete chaotic systems are based on known parameters and fractional orders of an original system [ 11 , 12 , 13 , 14 ].…”

Research on fractional-order discrete chaotic systems has grown in recent years, and chaos synchronization of such systems is a new topic. To address the deficiencies of the extant chaos synchronization methods for fractional-order discrete chaotic systems, we proposed an improved particle swarm optimization algorithm for the parameter identification. Numerical simulations are carried out for the Hénon map, the Cat map, and their fractional-order form, as well as the fractional-order standard iterated map with hidden attractors. The problem of choosing the most appropriate sample size is discussed, and the parameter identification with noise interference is also considered. The experimental results demonstrate that the proposed algorithm has the best performance among the six existing algorithms and that it is effective even with random noise interference. In addition, using two samples offers the most efficient performance for the fractional-order discrete chaotic system, while the integer-order discrete chaotic system only needs one sample.
