This paper proposes a block encryption algorithm based on a new chaotic system that combines generative adversarial networks (GANs) and DNA sequence coding. First, the new one-dimensional chaotic system that combines GANs with DNA sequence coding generates two more complex key stream sequences. Then, the two different random sequences are combined with an improved Feistel network by utilizing the product of the block matrix to encrypt the image to scramble and diffuse the image. Finally, the security performance of this algorithm is quantitatively analysed. The simulation results show that the proposed chaotic system has a large key space, and the new algorithm yields adequate security and can resist exhaustive attacks and chosen-plaintext attacks. Therefore, this approach provides a new algorithm for secure transmission and protection of image information.

“…Since Fridrich first proposed the scheme of image encryption based on chaos in 1998 [19], most image encryption methods adopt permutation-diffusion encryption model, which has been proved to have good performance [20,21,22,23,24]. since permutation and diffusion operations are carried out separately and independently, and in order to achieve good diffusion effect, permutation and diffusion operations for the same pixel value are usually performed in multiple rounds, which will undoubtedly increase the complexity of the algorithm and reduce the encryption efficiency.…”

An Efficient and Secure Image Encryption Algorithm Based on Non- Adjacent Coupled Maps

In this paper, an image encryption algorithm based on non-adjacent coupled map lattices is designed. Compared with coupled map lattices, non-adjacent coupled map lattices have few periodic windows in bifurcation, and larger parameter range in chaos dynamics. Combined with the proposed chaotic system, a new alternative encryption structure between permutation, diffusion and substitution is proposed to improve the security and encryption efficiency of the algorithm. In the diffusion process, multiplication operation in GF (257) and addition operation in GF (2) based on look-up table are adopted, which improves the encryption efficiency and enhances the permutation effect by choosing pixel value in Latin Square during the diffusion process. Moreover, based on the good cryptographic characteristics of the s-box, a dynamic sbox related to plaintext is constructed to substitute plaintext pixels. Experimental results and security analysis show that the proposed encryption scheme can resist all types of typical attacks and has good encryption effect.

“…These characteristics can effectively improve the information security of image encryption system [8]- [9]. Therefore, many image encryption algorithms based on chaotic system have been proposed [10]- [11]. Because one-dimensional chaotic system is easy to realize, a variety of image encryption schemes are designed based on one-dimensional chaotic system.…”

This paper introduces a novel one-dimensional sine chaotic system (1DSCS) with large parameter interval. The evaluation of 1DSCS indicates that the system has good chaotic characteristics and large parameters space. Based on 1DSCS, a new image encryption scheme is proposed. First, the image is scrambled by the row and column indexes, and then scrambled by the dynamic parameters Arnold map. This scheme avoids the inadequacy of row-column index scrambling and the periodicity of Arnold map. Second, four highly sensitive dynamic diffusion formulas related to plaintext are designed, and the dynamic formulas are selected through the chaotic sequence generated by 1DSCS. Third, the scheme proposed in this paper can also be applied to color image encryption. The experimental results demonstrate that the 1DSCS system is suitable for image encryption and the encryption scheme has good security to resist common attacks.
