“…Image chaotic encryption algorithms have attracted some special attention in the field of information security [1][2][3][4][5][6][7]. In recent years, many image chaotic encryption schemes combined chaos theories with other technologies, such as one-time keys [8], bit-level permutation [9], DNA operations [10][11][12][13], parallel computing system [14], matrix semi-tensor product theory [15], cellular automata [16,17], neural network [18,19], Latin square or Latin cube [20][21][22], and so on, have been proposed. However, the security issues of image chaotic encryption algorithms have also attracted much attention.…”

“…Therefore, the equivalent secret keys can be obtained by selecting 512 plain images. In [25], the cryptanalysis of a DNA encoding-based image scrambling and diffusion encryption algorithm proposed in [10] is reported to find that the scrambling algorithm is also independent of plain image, so that it can be deciphered by chosen plaintext attack. In addition, by choosing some specific plain images, the original image chaotic encryption algorithm can be simplified into scrambling-only encryption algorithm, which has been proven to be insecure [26,27].…”

In this paper, the security analysis of an image chaotic encryption algorithm based on Latin cubes and bit cubes is given. The proposed algorithm adopts a first-scrambling-diffusion- second-scrambling three-stage encryption scheme. First, a finite field is constructed using chaotic sequences. Then, the Latin cubes are generated from finite field operation and used for image chaotic encryption. In addition, according to the statistical characteristics of the diffusion image in the diffusion stage, the algorithm also uses different Latin cube combinations to scramble the diffusion image for the second time. However, the generation of Latin cubes in this algorithm is independent of plain image, while, in the diffusion stage, when any one bit in the plain image changes, the corresponding number of bits in the cipher image follows the change with obvious regularity. Thus, the equivalent secret keys can be obtained by chosen plaintext attack. Theoretical analysis and experimental results indicate that only a maximum of 2 . 5 × w × h 3 + 6 plain images are needed to crack the cipher image with w × h resolution. The size of equivalent keys deciphered by the method proposed in this paper are much smaller than other general methods of cryptanalysis for similar encryption schemes.

This paper first discusses a fractional-order Liu system of order as low as 2.7 and shows its chaotic characteristics by carrying out numerical simulations such as Lyapunov exponents, bifurcation diagrams and phase portraits. Then, by using the topological horseshoe theory and computer-assisted proof, the existence of chaos in the system is verified theoretically. Finally, the fractional-order system is implemented on a Field Programmable Gate Array (FPGA) and the results obtained show that the fractional-order Liu system is indeed chaotic.

“…Moreover, in [26], a novel image encryption scheme was proposed based on reversible cellular automata combining chaos. In [27,28], image encryption schemes based on DNA sequence operations rule and some improved chaotic systems were proposed, and an image encryption algorithm based on wave function and chaotic system was given in [29] where keystream was dependent on both the plain image and the secret key. However, some chaos-based image encryptions had been broken [30][31][32][33][34].…”

Abstract:The composite discrete chaotic system (CDCS) is a complex chaotic system that combines two or more discrete chaotic systems. This system holds the chaotic characteristics of different chaotic systems in a random way and has more complex chaotic behaviors. In this paper, we aim to provide a novel image encryption algorithm based on a new two-dimensional (2D) CDCS. The proposed scheme consists of two parts: firstly, we propose a new 2D CDCS and analysis the chaotic behaviors, then, we introduce the bit-level permutation and pixel-level diffusion encryption architecture with the new CDCS to form the full proposed algorithm. Random values and the total information of the plain image are added into the diffusion procedure to enhance the security of the proposed algorithm. Both the theoretical analysis and simulations confirm the security of the proposed algorithm.
