“…The histogram is the distribution of distribution and the statistical intensity of the pixels of an image. The histogram analysis also functions to determine th e statistical performance of the image encryption algorithm [24]. The cipher image histogram must be very different from the plain image and have a uniform distribution of each pixel intensity.…”

“…Cryptographic research on images has been widely developed as in research carried out in [14][15][16][17][18][19][20][21][22][23]. Cryptography in images uses more permutation and diffusion techniques such as chaotic or shifting algorithms [14,24,25], this is because methods such as AES, DES and RSA Bulletin of Electr Eng & Inf ISSN: 2302-9285 …”

One popular image security technique is image encryption. This research proposes an image encryption technique that consists of three encryption layers, i.e. bit-shift encryption, chaos-based encryption, and stream encryption. The chaos algorithm used is Arnold's chaotic map, while the stream cipher algorithm used is RC4. Each layer has different cryptology characteristics in order to obtain safer image encryption. The characteristics of cryptology are permutation, confusion, diffusion, and substitution. The combination of the proposed encryption method aims to secure images against various attacks, especially attacks on statistics and differentials. The encryption method testing is done by various measuring instruments such as statistical analysis, i.e. entropy information, avalanche effect, and histogram, differential analysis, i.e. UACI and NPCR, visual analysis using PSNR and SSIM, and bit error ratio. Based on the results of experiments that the encryption method that we propose can work excellently based on various measurement instruments. The decryption process can also work perfectly this is evidenced by the ∞ value based on PSNR, and zero value based on SSIM and BER.

“…The authors in Ref. [20] proposed an effective bit-level image encryption plan based on a 3D cat map, reverse 3D cat map and an improved class of chaotic maps with Markov properties. In this strategy, firstly, the plain-image is converted into a binary matrix, and then the sum of all the bits in this matrix is used as part of the secret keys; secondly, a mapping is designed; and, thirdly, a chaotic map with Markov properties is used in the diffusion process.…”

With the extensive recent development of communication methods and resulting increase in data surveillance and espionage, the need for reliable data encryption methods is greater than ever. Conventional encryption calculations, for example, DES and RSA, are not beneficial in the field of picture encryption because of some inherent characteristics of pictures such as bulk data size and high redundancy, which are problematic for conventional encryption. Many researchers have proposed different image encryption schemes to overcome image encryption problems. In the last two decades, more and more studies have looked to incorporate conventional encryption methods and the complex behavior of chaotic signals. In this paper, a novel image encryption algorithm is proposed based on pixel chaotic permutation. A chaotic logistic map and Ikeda map are used to design a new pseudo-random bit generator, and a novel permutation scheme is used to modify pixel values. Then, a new permutation algorithm based on a traditional Japanese game called Amidakuji is used for pixel scrambling. Different statistical manners, such as correlation coefficient, NPCR (Number of Pixels Change Rate), UACI (Unified Average Changing Intensity), and entropy, are used to provide analysis of the effectiveness of the proposed encryption methods. Our example reveals that the proposed encryption method can obtain highly secure encrypted images using a novel chaotic permutation method based on Amidakuji.

“…Ideal encryption scheme should reduce the correlation of adjacent pixels. From the plain images (lena, baboon, pepper) and from the encrypted images (lena, baboon, pepper), 10 3 adjacent pixels are selected in the horizontal, vertical and diagonal directions to calculate their correlation coefficients by using following equations [36]:…”

A Novel Design of Cryptographic SP-Network Based on Gold Sequences and Chaotic Logistic Tent System

et al. 2019

Substitution permutation network (SP-network) is a chain of linked mathematical primitives used in block cipher algorithms. The proposed novel design of cryptographic SP-network consists of three cryptographic primitives: substitution box, permutation box, and random key sequences, including one key whitening operation. A new design is being proposed for each cryptographic primitive. The cryptographic strength of the proposed SP-network is evaluated by employing various standard tests; strict avalanche criterion, differential approximation probability, bit independent criterion, linear approximation probability, nonlinearity test, unified averaged changed intensity, histogram analysis, and coefficient correlation tests. The outcomes of the investigations validate that the designed cryptosystem is stable for secure communication and attains better cryptographic strength as compared with other state-of-the-art techniques.
