“…For a comprehensive comparison, we use the logistic chaotic sequence under the same parameter to act on the operation of the DNA sequence. Additionally, histogram, information entropy [ 49 ], rate of base distribution, hamming distance [ 50 ], fixed point ratio [ 51 ], histogram variance [ 52 ], correlation coefficient, and the number of pixel change rate (NPCR) and unified average changing intensity (UACI) are used as the evaluation indexes. The relevant theories of these evaluation indexes are given by the following Eqs ( 3 )–( 16 ).…”

Because a DNA nucleotide sequence has the characteristics of large storage capacity, high parallelism, and low energy consumption, DNA cryptography is favored by information security researchers. Image encryption algorithms based on DNA coding have become a research hotspot in the field of image encryption and security. In this study, based on a comprehensive review of the existing studies and their results, we present new insights into the existing image encryption algorithms based on DNA coding. First, the existing algorithms were summarized and classified into five types, depending on the type of DNA coding: DNA fixed coding, DNA dynamic coding, different types of base complement operation, different DNA sequence algebraic operations, and combinations of multiple DNA operations. Second, we analyzed and studied each classification algorithm using simulation and obtained their advantages and disadvantages. Third, the DNA coding mechanisms, DNA algebraic operations, and DNA algebraic combination operations were compared and discussed. Then, a new scheme was proposed by combining the optimal coding mechanism with the optimal DNA coding operation. Finally, we revealed the shortcomings of the existing studies and the future direction for improving image encryption methods based on DNA coding.

“…We can know that the voice signal is completely covered by the chaotic signal, and the original shape could not be seen at all after the voice signal and the chaotic signal generated by the driving system is superimposed. The cracker could not get any information of the voice signal from the channel [29][30]. It has proved that the switching encryption method has pretty good privacy.…”

This paper proposed a novel switching scroll hyperchaotic system based on a memristor device and explored its application to secure communication. The new system could be switched between the double-scroll chaotic system and multiscroll one by switch S1 and switch S2. We gave the construction process of the novel system, its numerical simulations, and dynamical properties, firstly. Moreover, the memristive circuit implementation of the new switching system was presented and the results were also in agreement with those of numerical simulation. Finally, the new switching memristive system was applied to secure communication by means of the drive-response synchronization with chaotic masking. When the voice signal is a rising waveform, it is encrypted by the double-scroll memristive system. When the voice signal is a falling waveform, the multiscroll memristive system works. The voice signal is completely submerged in the chaotic signal and could not be distinguished at all. Security analyses show that it is a successful application to secure communication.

“…Hence,the key space of our encryption algorithm is larger enough against brute-force attacks. So the secret key space of the algorithm are 2 24 , which is larger than the one of [24] and [25]. Moreover, the adaptive controllers and parameter update laws are some functions with other variables and parameters, which must be known to decrypt.…”

Many works on hybrid projective synchronization (or simply 'HPS' for short) of nonlinear real dynamic systems have been performed, while the HPS of chaotic complex systems and its application have not been extensively studied. In this paper, the HPS of complex Duffing-Holmes oscillators with known and unknown parameters is separately investigated via nonlinear control. The adaptive control methods and explicit expressions are derived for controllers and parameters estimation law, which are respectively used to achieve HPS. These expressions on controllers are tested numerically, which are in excellent agreement with theory analysis. The proposed synchronization scheme is applied to image encryption with exclusive or (or simply 'XOR' for short). The related security analysis shows the high security of the encryption scheme. Concerning the complex Duffing-Holmes oscillator, we also discuss its chaotic properties via the maximum Lyapunov exponent.
