“…There are no detectable correlations between the plain-images and their corresponding cipher-images. We also perform the comparison of dajacent pixel correlation with Wang's algorithm [26], Chen's algorithm [27] and Chen's algorithm [28]. In our proposed scheme, the correlation coefficients are significantly reduced than other algorithms, we can intuitively see the changes from Table 2.…”

“…The distribution of the pixel space will be more uniform when the value of information entropy is bigger. Compared with Wang's algorithm [26], Chen's algorithm [28] and Zhang's algorithm [29], our proposed algorithm obtains better results in Table 3 and Table 4. We employ four 256 gray scales standard test images with the size of 256 256…”

“…The expectation value of NPCR and UACI are 99.6094% and 33.4636%. Table 7 indicates that the performance of the proposed algorithm is better than Wang's algorithm [26], Chen's algorithm [27] and Chen's algorithm [28] when encrypting images one round. Therefore, one round of encryption by our proposed scheme is secure enough to resist differential attack.…”

“…The comparison also demonstrates that the proposed image encryption scheme is superior. For example, the correlation between adjacent pixels is significantly reduced compared with Wang's scheme [26], Chen's schemes [27,28]. Moreover, we introduce co-occurrence histogram to reflect the encryption effect of the cipherimage.…”

Image encryption has variety of applications in the healthcare, military, e-commerce, and education sectors. Along with processing images for various applications, secure storage of such images is essential. For many years, encryption of images is a fruitful method for the secure transmission of multimedia data that carries sensitive information across multiple mediums. There is umpteen number of image encryption methods available which exhibit improved performance either in time, space, or susceptance to attacks in a controlled environment. Few image encryption algorithms have higher computational complexity, whereas some are immune to a handful of attacks (either differential, statistical, brute force, or known-plaintext and chosen-plain text attacks). We have developed a novel chaos-based image encryption algorithm-PixJS for 8-bit grayscale images based on linear feedback shift register, logistic map, and jumbling process. The algorithm was initially proposed for the text-based passwords called as jumbling-salting algorithm in 2014. We conducted a comprehensive analysis of the proposed algorithm on sets of symmetric and asymmetric images (10 samples each) and addressed four research questions primarily based on speed and security parameters. After conducting thorough experimentation, we found that our algorithm outperformed existing algorithms in security and has proven to be resistant to statistical, differential, brute-force, known plain text, and chosen plain text attacks.

In this paper, a new image encryption algorithm employing the combination of chaos and cellular automata is proposed. The proposed algorithm consists of both permutation and diffusion stages. While the permutation process is carried out using logistic map and Conway's game-of-life cellular automata, the diffusion process is carried out using Chebyshev map and Lorenz equation. Further, a complex matrix generated from the plain image is used as an additional component in the diffusion process, which enables the encrypted image to exhibit a strong sensitivity to the input image. The proposed algorithm has been tested with various input images, and the performance is compared with other existing algorithms. The performance metrics obtained on the developed algorithm such as high key space, ideal number of pixels change rate and unified average changing intensity values, and very less correlation among the adjacent pixels demonstrate the high effectiveness and security features of the proposed algorithm.
