Classical one-dimensional chaotic map has many ideal characteristics which is quite suitable for many different kinds of scientific fields, especially cryptography. In this paper, we propose an idea of constructing high-dimensional (HD) cyclic symmetric chaotic maps by using one-dimensional (1D) chaotic map. Two constructed 3D cyclic symmetric chaotic maps are taken as the examples, named three-dimensional cyclic symmetric logistic map (3D-CSLM) and three-dimensional cyclic symmetric Chebyshev map (3D-CSCM), respectively. Numerical experiments show that the new maps possesses better dynamical performances, and their parameters have a wider range, compared with the original map. Furthermore, to verify its effect in image encryption, a novel image encryption algorithm based on 3D-CSLM and DNA coding is proposed. DNA method for image encryption can improve the efficiency of permutation and diffusion. Firstly, the algorithm uses 3D-CSLM to generate chaotic sequences for DNA operation rule selection and pixel permutation. Then through the DNA XOR operation to achieve diffusion, and finally form an encrypted image. Several simulation tests results indicate that the proposal has a promising security performance and strong anti-attack ability.

“…Many new methods have emerged, such as image watermarking [2]- [3], data hiding [4]- [5], and image encryption has attracted extensive research as one of the most intuitive methods. Due to the large data volume, high correlation, and high redundancy of images [6], traditional data encryption algorithms such as AES, DES, RSA, and IDEA are not the optimum choices for image encryption [7]. In recent years chaotic systems have proven to be well suited for image encryption because of their extreme sensitivity to initial values, pseudorandomness, unpredictability, and ergodicity [8]- [10].…”

With the increasing development of information technology, image information security has received more and more attention. Furthermore, image encryption is one of the most powerful methods to ensure image information security and plays a vital role in modern society. This paper proposes an image encryption algorithm based on an improved lifting-like structure and cross-plane zigzag transform. First, to overcome the problem of simple original lifting-like structure and single update function. We modularize the original image and add new update functions and prediction functions to handle the information between different modules. Our proposed structure has higher encryption quality and can better spread the information between each image pixel. Secondly, we propose a cross-plane zigzag transform, which can effectively eliminate the correlation between adjacent elements of the original image by applying the zigzag transform to the replacement between different planes, overcoming the disadvantage that the traditional zigzag transform is limited in scanning mode and challenging to resist brute-force attack. The experimental results show that compared with other state-of-the-art schemes, this scheme has higher information entropy, can well resist selective plaintext attacks and differential attacks, and has better security.

“…Hence, the plaintext sensitivity feature must be embedded in the future ciphers. Many image ciphers have been written based on the scrambled images [1,[11][12][13]. In [11], Langton's Ant cellular automaton has been employed in combination of the 2D scrambled image to develop an image cipher.…”

Security of images plays an import role in communication in current era due to the popularity and high usage of multimedia content in the Internet. Image security is described as applying an encryption algorithm over the given plaintext images to produce cipher images that can be transmitted safely over the open channel, the Internet. The problem which plagues these image ciphers is that they are too much time consuming, and that do not meet the dictates of the present times. In this paper, we aim to provide an efficient image cipher. The previous studies employed many constructs like Langton's Ant, 15 puzzle game and Castle in the 2D scrambled image based image ciphers, which had grave implications related to the high execution time of the ciphers. The current study directly made use of the 2D scrambled image to realize the purpose. Moreover, no compromise has been made over the security of the proposed image cipher. Random numbers have been generated by triggering the Intertwining Logistic Chaotic map. The cipher has been subjected to many important validation metrics like key space, information entropy, correlation coefficient, crop attack and lastly time complexity to demonstrate its immunity to the various attacks, and its real world application. In this paper, our proposed image cipher exhibits an encryption speed of 0.1797 s, which is far better than many of the existing encryption ciphers.
