A Novel Color Image Encryption Algorithm Based on Three-Dimensional Chaotic Maps and Reconstruction Techniques

Abstract

In the paper, a novel color image encryption scheme is proposed by use of the threedimensional chaotic maps and some data reconstruction techniques. In the diffusion process of the encryption algorithm, the three-dimensional chaotic Logistic map is introduced to changes the pixel value of the plain image. Meanwhile, in the confusion process, the three-dimensional chaotic Cat map is applied to deal with the position of the image pixels. Moreover, some data reconstruction techniques are employed for the better encryption result. Furthermore, the corresponding decryption algorithm is also given. The significant advantages of our method are the effectiveness and simplicity, and our proposed method breaks the correlation between image pixel layers, offers a large key space and against differential and statistical attacks effectively. Finally, the superiority of the proposed algorithm will be shown by the experimental results, security analysis, and the corresponding comparisons with literature.

“…2022 is effective at repelling the entropy attack. If the entropy is significantly less than the maximum value, however, the encoded image is ineffective and cannot withstand an entropy attack [24][25][26][27]. The following formula is used to calculate entropy:…”

Efficient Image Encryption Based on New Substitution Box Using DNA Coding and Bent Function

“…During the digital transmission process of data through public channels, the data is exposed to be missed. Stolen password of image is applied by data loss attack in which the attackers seek to remove parts of the data [45]. So, various data loss sizes were made to test the level of enciphered images' recovery.…”
