“…In the diffusion phase, the pixel values are modified with the manner that a minor change at one pixel level of the plain image leads to the corresponding cipher image to be significantly different. Therefore, many variants and improvements of the main architecture of chaos-based schemes are proposed including [4][5][6][7][8][9]43,44]. In [4], a combined architecture of both permutation-diffusion is considered as one phase is proposed, for the purpose of avoiding the duplicated scanning effort for obtaining pixel values, and improving the runtime, the scheme is resisted to known and chosen plaintext attacks by taking into account the extraction of information from the plain image.…”

This paper presents a new symmetric scheme for enciphering digital images. The proposal is based on the combination of chaos and cellular automata (CA) under the scenarios of one round enciphering/deciphering and permutation-diffusion architecture. All the generated key-streams in the proposed cryptosystem are based on the use of an improved one-dimensional (1D) chaotic system [i.e., logistictent system (LTS)] with excellent chaotic properties.These key-streams are related to both the secret key and the characteristics of the plain image. Before applying the encryption process, one pixel of the plain image at a random position is overwritten by inserting the weighted histogram value as a new measure to represent the plain image's features, this pixel withholds the encryption routine and further will be used to guarantee the resistance to known/chosen plain image attacks (CPA secure). In the confusion phase, a bit-level permutation is adopted with the generated one-time keystreams using an improved 1D chaotic system. This strategy of shuffling is handled in which besides to the modification of each pixel's position, its value is also changed, to further render the achievement of both confusion and diffusion possible within just this phase. The diffusion phase is divided into two subphases: In the first one, the value of each pixel is changed sequentially by means of an improved one-dimensional chaotic system, to fasten the diffusion process and spread the influence of a single bit over the others, and in the second subphase, two-dimensional reversible memory cellular automata are associated with quadtree decomposition strategy and applied to the output of the first subphase, to enhance both the security and the diffusion effect of the cryptosystem. Security analysis shows the capacity of the proposed scheme to resist the commonly known attacks besides to its competitive speed that traces its suitability for practical image encryption.

“…However, most [4][5][6] are based on Fridrich's permutation-substitution model [7] and demonstrate statistical correlations among the plain image, the cipher image, and the key. Previous studies [8,9] proved that 96.7% of the bit values were unchanged using Fridrich's encryption structure. To reduce redundancy and statistical links, many bit-level-based techniques have been proposed [10][11][12][13][14][15][16].…”

A novel chaos-based image encryption scheme has been proposed recently. In this scheme, redundancies of the Fridrich's structure were reduced significantly via a new circular inter-intra-pixels bit-level permutation strategy. However, we proved that the original encryption scheme is vulnerable to the known/chosen-plaintext attacks. Both the permutation and diffusion phases have been improved to enhance the security of the original scheme. By shifting each row of the plain image randomly, known-plaintext attacks could be resisted. Furthermore, by appending double crossover diffusion to the end of the original scheme, chosen-plaintext attacks lost their efficacies. Simulation results demonstrated that the improved encryption scheme outperforms the original one.

“…Therefore certain diffusion effect has been introduced in the confusion stage with a bit-level permutation. Thanks to the superior characteristics of bit-level operations and the intrinsic bit features of images, Zhang et al proposed a novel image encryption scheme using lightweight bitlevel confusion and cascade cross circular diffusion in [23] .They also applied an expand-andshrink strategy at bit-level to shuffle the image with reconstructed permuting plane [24]. All the proposed image encryption schemes show good performances compared with the traditional permutation-diffusion structure operating at pixel-level.…”
