“…The cipher image is obtained by XORing the image pixels with the iterated hyperchaotic sequences. In [20], Sathish Kumar et al suggested the dual chaos based medical image encryption algorithm, where the shuffling and scrambling are done through chaotic circular shifting. In [21], a tri layer cryptic system based on Latin square image cipher, Rubik's cube and discrete Gould transform has been designed to shuffle, scramble and authenticate the DICOM.…”

“…But because of its structure simplicity, these encryption techniques can easily be cryptanalyzed by many methods such as phase regression image, space reconstruction, or nonlinear prediction. As a result of the emergence of the multi-dimensional image processing technologies, and multivariable networks, the cryptosystem's designers developed multi-dimensional chaos-based image cryptosystems [8], hyper-chaos-based image cryptosystems [36]. However, these image cryptosystems have been cryptanalyzed and demonstrated insecurity and they also exposed some inner flaws [2,8,21,23,34,35,39].…”

This paper introduces a secure chaos-based model for ciphering and deciphering of digital images. The proposed approach is composed of successive confusion and diffusion stages. The confusion stage is repeated n rounds using a different key in each round. The output of the confusion stage is subjected to diffusion stage which is repeated m rounds with a different key for each round. The nested iterations in the confusion and diffusion stages with a different key for each round enlarges the key space which enhances the proposed image cryptosystem security level. A security investigation is done on a family of 2D chaotic confusion maps to select the one with highest security level to be used with the proposed image cryptosystem. The results demonstrated that the Standard map has the highest security level among the examined 2D chaotic confusion maps because it is more complicated and it has a large key space. The proposed image cryptosystem is compared to other three recent image cryptosystems using different security analysis factors including statistical tests, key space analysis, information entropy test, maximum deviation analysis, irregular deviation analysis, and avalanche effect differential analysis. The results demonstrated that, the proposed image cryptosystem with Standard map outperforms all of the other examined image encryption techniques from security point of view.

“…In this technique, the circular shifting of rows and columns has been controlled through the logistic and Bernoulli chaotic maps. Scrambling followed by the diffusion enables the method stronger against statistical attacks [12]. Combining multiple chaotic maps can provide more robust encryption which also improves confidentiality.…”
