In recent years, the field of information science has seen a surge in research focused on digital image security. Chaotic systems have emerged as essential tools in the development of image encryption algorithms due to their unpredictability and sensitivity to initial values. In this paper, a novel three-dimensional chaotic system is proposed and its chaotic behavior is validated through an analysis of dissipative properties, phase diagrams, spectral entropy, Lyapunov indices, etc., and more. Leveraging chaotic mapping, a color image encryption algorithm utilizing rotational arithmetic element shuffling and dna coding is proposed and executed. Validation through simulation experiments and numerical analyses demonstrates the algorithm's reliability and security.

This work presents a grayscale image encryption algorithm based on delayed chaotic system, and dna coding with cross-layer techniques, which mainly includes random sequences generation, dna encoding and decoding, dna cross-layer confusion operations, pixels cross-layer diffusion. Concrete, firstly, information entropy and the correlation values of original images are combined as the initial value of the delay chaotic system, establishing the relationship between original images and the delayed chaotic system and enhance the relationship between the encrypted images and original images to resist chosen-plaintext and known-plaintext attacks. Secondly, after coding the pixels of images by dna rules, cross-layer techniques are designed to rearrange the positions of all dna coding elements using the corresponding the delayed chaotic sequence matrices to achieve confusion effects. Finally, the dna decoded pixels are divided into four blocks (layers), combining with the state sequences of the delayed chaotic system for cross-layer diffusion operations to complete the final image encryption. The presented image encryption algorithm using cross-layer and dna coding techniques has considerable advantages compared with the same type of dna chaotic encryption algorithms, such as key space and sensitivity, information entropy, UPCR and UACI values, efficiency, etc., thus verifying that the delayed chaotic system is conducive to the improvement of information security.

In recent years, a number of image encryption schemes based on dna coding and nonlinear dynamics have been proposed. Generally, these dna-based schemes first encode plaintext images into dna sequences and then encrypt them with pseudorandom elements produced by chaotic systems or other nonlinear dynamics. Although ciphertexts can pass some security tests, many image encryption schemes are being shown to have intrinsic flaws and that they cannot guarantee a high level of security. In this article, we cryptanalyze a family of image encryption schemes for which the encryption kernel is dna coding or its variant. The complex dna operation can be simplified as a substitution box (S-box). The whole cryptosystem's security level is thus significantly decreased and is vulnerable to the chosen-plaintext attack. Applications of this concept to break five ciphers are theoretically presented and experimentally verified. In addition, some suggestions for resisting similar attacks are also given in this article.

In recent years, encryption algorithms have undergone rapid development, finding extensive applications across diverse industries. In the pursuit of enhancing the security of image encryption methodologies, this paper introduces a novel computational holographic encryption approach grounded in dna coding and bit-plane decomposition. The encryption framework employs a Logistic-Sine chaotic mapping system characterized by a substantial key space to control encryption particulars. The plaintext image undergoes encryption through the input-output algorithm of computational holography. This algorithm shifts information from the spatial domain, represented by the greyscale map, to the frequency domain, concealing the distribution of pixel values. The incorporation of dna coding and bit-plane transformations serves to intensify the chaos within the ciphertext image, thereby maximizing the efficacy of the encryption process. By integrating principles from biology and physical optics into encryption methodologies, this approach amalgamates diverse scientific domains. Simulation results and data analyses substantiate that the proposed encryption algorithm adeptly withstands various attacks, attesting to its security and reliability.

The paper proposes an improved reversible substitution method to hide data into deoxyribonucleic acid (dna) sequence, and four measures have been taken to enhance the robustness and enlarge the hiding capacity, such as encode the secret message by dna coding, encrypt it by pseudo-random sequence, generate the relative hiding locations by piecewise linear chaotic map, and embed the encoded and encrypted message into a randomly selected dna sequence using the complementary rule. The key space and the hiding capacity are analyzed. Experimental results indicate that the proposed method has a better performance compared with the competing methods with respect to robustness and capacity.

With the rapid development of information technology in the fi eld of electronic medicine, the confidentiality of medical images has received increasing attention. The research on the encryption of multiple medical images holds greater practical significance. In this paper, the encryption algorithm is designed specifically for the region of interest ( ROI ) in medical images. Different techniques and methods are used to encrypt ROI and region of non-interest ( RONI ) respectively. By combining improved Zigzag scrambling, dna coding, and the Fisher-Yates shuffle, we place an emphasis on protecting the ROI, and achieve secure encryption for medical images of any number and size. In addition, a new one-dimensional chaotic system S-LCS with larger parameter space and better chaotic properties is proposed. In this encryption scheme, the information about the ROI serves as the secret key, and the initial values and parameters of the chaotic sequences required for encryption are calculated from this key. This strengthens the relationship between the key and the plaintext, enhancing the security of the key. Through testing and comparative analysis, it has been found that the encryption algorithm has high enough security, can resist various attacks, and has high encryption efficiency in the application scenario of multi-image encryption.

A novel image encryption algorithm based on hyperchaos and dna encoding is proposed in this paper. Unlike the traditional dna-based encoding method, a more fine-grained encryption approach is adopted, which enhances the security of the system. To address the inherent binary arithmetic limitation of traditional dna computing, the authors develop a novel symmetric and reversible dna subtraction operation that fully utilizes the encryption advantage of dna computing. To enhance security, the authors introduce a dna crossover mechanism based on pixel, which can generate different ciphertexts even for the same pixel values. In the algorithm, the authors propose a diffusion strategy that combines left diffusion, right diffusion, and XOR parameters. This strategy not only ensures the avalanche effect, where even a single pixel change in the plaintext image will cause a drastic change in the ciphertext image, but also greatly enhances the security of the algorithm. Experimental results and performance analysis indicate that the authors' proposed system has good encryption performance and the ability to resist noise attacks and clipping attacks. This paper proposes an image encryption algorithm based on hyperchaotic system and dna encoding. The system uses the hyperchaotic Chen system to generate the initial key, and uses dna encoding to encode, calculate, and decode the image to achieve functions such as pixel scrambling and diffusion within the image. Experimental results show that this algorithm has good security, and the encrypted images have good statistical characteristics, and the cipher images have low internal pixel correlation and high image information ***

Substitution boxes are very important for cryptographic structures. But getting an 8-bit strong s-box is a difficult problem. To address this problem, a new approach is proposed in this study. dna chains are used in the proposed approach. First of all, a weak s-box is obtained with the help of a chaotic map. Then, a dna chain is formed with the same chaotic map. In this study, 2000-long dna chains were produced. Then, two random values consisting of four components are determined from these dna chains, and these values are addressed to the s-box structure. By changing the places of these values, the s-box structure is improved up to a certain iteration. In this study, 10,000 iterations were examined, and three different strong s-boxes were obtained by using three different dna chains. The nonlinearity values of these s-box structures were observed as 110.25, 110.5, and 110.75, respectively. The proposed study has proven to work effectively with effective results in three different chains. In addition, it has been proven as a result of the analysis that the proposed s-box structures also have other cryptographic features. The proposed algorithm has surpassed many s-box generation philosophies in the literature. In addition, the proposed algorithm will provide serious gains to cryptographic structures that will be developed in the future.

In recent years, image watermarking has attracted considerable research interest, especially jointing with chaotic map and dna sequences. In this work, we propose a novel architecture of image watermarking using chaotic map and dna coding. Firstly, two logistic chaotic maps are used to structure a secure architecture with embedding watermarking into the LSB (least significant bit) of cover image. Analyzing numerical experimental results and comparing with previous works show that the proposed architecture possesses higher security than previous works. Then the method of dna coding is jointed into the architecture to improve the ER (embedding rate). It not only significantly increases the ER, but also accelerates the development of dna-based watermarking. The improved architecture is suitable for protecting the copyright of cover image in dna-based information security. (C) 2015 Elsevier GmbH. All rights reserved.

In this groundbreaking study, we introduce a novel and highly advanced approach to image encryption, harnessing the power of chaotic Beta wavelet sequences and dna coding. Unlike conventional methods, our methodology not only involves the generation of three intricate chaotic beta wavelet sequences but also integrates dna coding with an XOR operation, ensuring an unprecedented level of security for the encrypted data. The strength of our work lies in the meticulous application of Beta Discrete Wavelet Transform (DWT) to encrypt images in the wavelet domain, adding an extra layer of complexity to the encryption process. This paper not only presents a cutting-edge solution for image security but also establishes a new paradigm in the field of encryption by seamlessly merging chaos theory, dna coding, and wavelet transforms. The results showcase unparalleled strength in safeguarding sensitive information, making our methodology a pioneering contribution to the realm of image encryption.
