“…Because chaotic systems/maps have some intrinsic properties, such as ergodicity, sensitive to the initial condition and control parameters, which are analogous to the confusion and diffusion properties specified by Shannon [1]. Thus makes it natural to employ chaotic systems in image encryption algorithms [2][3][4][5][6][7][8][9][10][11]. Therefore, many chaotic image encryption algorithms have been developed by directly utilizing existing chaotic systems/maps [8][9][10][11].…”

“…As mentioned in Section 4 of [1], x(0) = avg 2 , and thus, it depends on sum(P), which in turn depends on the plaintext P, as per Equations (2) and (3). In the chosen plaintext attack scenario [20] considered by Wang and Guo, the attacker is given the ability to request the encrypted image C for any chosen plain image P of the attacker's choice.…”

Wang and Guo (Nonlinear Dyn 76(4): 1943-1950 proposed a new image alternate encryption algorithm based on chaotic map. The image alternate encryption can be conceptually treated as a block cipher where a round function which provides both confusion and diffusion is applied on a plain image iteratively. After performing the round function for T iterations, the processed image is denoted as the encrypted image. We analyse the security of Wang and Guo image encryption scheme, especially from cryptographic point of view, in line with the designers' approach in their security analyses. Negatively, we show that the image encryption scheme is vulnerable to an impossible differential attack (a type of chosen plaintext attack) and a divide-and-conquer attack when a large all black image is encrypted. This paper serves as another important security result showing that any future design of image encryption schemes based on chaotic map should be evaluated through systematic cryptanalytic approaches which include impossible differential attack. To the best of our knowledge, this is the first impossible differential attack applied on an image encryption algorithm.

In recent years, image encryption has attracted much attention. Particularly, due to large data capacity and high correlation among pixels, chaos-based image encryption algorithms are more suitable to be applied in the digital image encryption. In this paper, we propose a novel chaotic image encryption algorithm, in which novel multiple chaotic systems and efficient self-adaptive model are initially mingled to enhance the security. Different from conventional algorithms, plaintext participates in the generation of cryptograph in a new way, which follows the idea from the perceptron model. The proposed algorithm enlarges the key space, enhances the randomness of the algorithm, and resists the differential attack effectively. Simulation results are demonstrated that proposed algorithm possesses the high security for the main current attacks, which is an excellent candidate for practical applications of image encryption.
