“…However, although the DNA coding technique contributed to improving the security of encryption, the extra time of coding and decoding limited its application in real-time communications. Li et al [45] accelerated their algorithm by achieving cross-plane scrambling and diffusion at the row level; however, diffusion in only one direction could not guarantee sufficient security against chosen-plaintext attacks. Zhang et al [46] converted a color image into a 2D matrix and then applied a multithread technique to reduce the time consumption of scrambling; however, the diffusion process was still traditional and inefficient.…”

Motivated by the pursuit of both encryption efficiency and security, this paper presents a symmetric color image encryption algorithm using a novel cross–plane joint scrambling–diffusion method. To provide high–strength security, the color planes are firstly spliced horizontally and then vertically to be adequately encrypted by the joint scrambling–diffusion method. Therefore, minor changes in any pixel can cross every color plane that significantly influences the final cipher image. To achieve fast encryption speed, all employed chaotic systems have simple structures but robust properties to rapidly generate high–quality pseudorandom sequences. Additionally, the joint scrambling–diffusion method is vectorized to handle pixels in parallel for satisfactory execution efficiency. Security tests demonstrate the outstanding security performance of the proposed algorithm, with correlation coefficients and entropies of cipher images being close to 0 and greater than 7.99, respectively, and results of NPCR and UACI tests being similar to ideal cipher images, which can resist statistical, differential, exhaustive, and even chosen ciphertext/plaintext attacks. Moreover, because of the O(4W + 4H) time complexity of the novel scrambling–diffusion method, even a color image with a size of 1024 × 1024 only costs 0.26 s to be encrypted. Hence, the proposed algorithm can satisfy the efficiency and security requirements of color image encryption.

“…Image compression can effectively solve this problem, reduce storage space, and save transmission bandwidth [16] adds compressed sensing technology on this basis, compresses and encrypts the plaintext image into a cipher image, and then embeds it into the carrier image to obtain a visually safe image of the same size. In these studies [43][44][45][46], there are still some shortcomings:…”

A new two-dimensional cosine-type Logistic map (2D-CTLM) is proposed in this paper. Performance analysis shows that 2D-CTLM has good ergodicity, complex behavior, and a wide range of chaotic regions. To study its application, an adaptive embedded high visual security image encryption scheme is proposed by combining the system with two-dimensional compression sensing to address the shortcomings of fixed embedding positions and low transmission efficiency in existing schemes. The embedding position is fixed when the ciphertext image is embedded into the carrier image. When embedded in an inappropriate location, it will affect the decryption quality and the imperceptibility of the steganographic image. Firstly, the initial value of 2D-CTLM system is generated by using the information entropy of plaintext image and counter to generate random measurement matrix, which is used to compress and encrypt plaintext image from two directions at the same time. Secondly, the compressed cipher image is scrambled by the initial matrix generated by the GOL (game of life) rules in two-dimensional cellular automata to obtain the ciphertext image. Finally, the most suitable embedding position in the carrier image is found by combining information entropy and edge entropy. Then the unquantized ciphertext image is embedded into it by ST (slant transform) embedding method to obtain a high visual security image. To improve the transmission efficiency, the color carrier image can be selected to transmit three gray plaintext images at the same time, maintain high-quality reconstruction effect. SHA-512 and the information entropy of plaintext image are used to generate the initial value of encryption and measurement matrix, enhance the correlation between the algorithm and plaintext image, and effectively resist known plaintext and selective plaintext attacks. Simulation results and performance analysis show that compared with the existing encryption schemes, the encryption scheme has excellent visual effect, good decryption quality and good robustness.

With technological advances, sharing sensitive information, such as multimedia data, especially images, is common. To protect the integrity of such data, advanced encryption algorithms are utmost necessary. The proposed encryption scheme introduces a novel approach that capitalizes on the distinct characteristics of users' authenticated usernames to dictate the sequence in which image blocks are encrypted. The methodology encompasses two key strategies. Initially, a set of four individual chaotic maps - Sin, Chebyshev, Logistic, and Gaussian - are employed for encryption. Also, the image blocks are encrypted with a novel 4D chaotic map. The process begins with segmenting an N×N×3 color image into its red, blue, and green constituents, each of size N×N. These constituents are further subdivided into four arrays, each sized (4×4) × (N/4) × (N/4). The encryption process for various image bands is based on the use of chaotic sequences generated by schemes 1 and 2. These resulting sequences serve as the fundamental encryption keys, guiding a variety of processes including both confusion and diffusion. The proposed encryption schemes, Scheme 1 and Scheme 2 were rigorously evaluated through extensive simulations, comparing their performance with a traditional algorithm. Both procedures demonstrated robustness against statistical analysis differential attacks and showcased NPCR and UACI values closely approximating ideal standards of 99.6 and 33.4, respectively. Notably, Scheme 2, employing the proposed 4D map, outperformed Scheme 1, which used four different chaotic maps, particularly in terms of NPCR and UACI. The schemes exhibited a significant key space of 2540, rendering decryption infeasible within an astronomical time frame of 9.449 × 10130 years. Further, entropy and correlation analysis validation revealed values close to 7.99 and 0, aligning with traditional algorithms' values. Additionally, pixel distribution analyses indicated uniformity along horizontal, vertical, and diagonal directions. The paper introduces an innovative encryption approach that capitalizes on user-specific characteristics and demonstrates superior security and performance compared to conventional methods.
