“…It is known that a cellular automaton (CA) can be used to encrypt images efficiently [6][7][8][9][10][11], and using an image scrambling algorithm can make the entire encryption system safer and more reliable [12][13][14]. In computer science and mathematics, the Josephus problem is a theoretical problem related to a certain counting-out game [15].…”

This paper proposes a new image scrambling algorithm based on the periodic characteristics of the Josephus ring. The algorithm composes the pretreatment part of the entire image encryption system and scrambles the rows and columns of the plain image. The Josephus scrambling algorithm is adjustable by using three kinds of parameters: step, m 0 , and n. Different values affect the size of the periodic value of the Josephus ring. In this paper, we focus on the method of determining the period of the Josephus cycle when the parameters are set and the Josephus rule space under arbitrary parameters. Because the Josephus ring is a mathematical problem, we analyze it using the group theory of modern algebra. After the Josephus scrambling, the plain image is encrypted. Because a CA is suitable for image encryption, the encryption part adopts a CA encryption algorithm using a one-dimensional, four-neighbor CA, which has chaotic behavior at the rules of 9d62 (hex). Finally, the number of pixels change rate, the unified averaged changed intensity test, and correlation detection are carried out on the experimental results. The results show that the use of the Josephus scrambling algorithm greatly improves the security of the entire encryption system.

“…Images transmission in the network must be encrypted to ensure the safety and secrecy of the images in many applications, such as military records and confidential business data. The common approach to protect the image is ordinary data encryption and steganography [1,2]. But there is a drawback of these techniques.…”

Secret image sharing is a useful way to protect a secret image by sharing it to several shadow images. The proposed scheme is an improvement of the secret image sharing method, in order to prevent the shadow images from revealing the shape of the original secret image. For the reason that the adjacent pixels of an image is highly close, the shadow images, the result of the general image sharing process, always give out the shape information of the secret which can be the main target of rivals. An improved method to solve this problem is using a function, also called the key, to permute the pixels of the original image before sharing process, but the custody of the key brings new troubles. The proposed scheme offers a special method to generate the key using the secret image itself, so there is no need to safeguard the key.

“…Unfortunately, these algorithms are vulnerable to chosen-plaintext attacks [1,23]. Consequently, many other encryption schemes that are not susceptible to this type of attack have been proposed [3,5,12,13,21].…”

This paper proposes a novel ARX model-based image encryption scheme that uses addition, rotation, and XOR as its confusion and diffusion mechanism instead of S-Box and permutation as in SP networks. The confusion property of the proposed scheme is satisfied by rotation and XOR with chaotic sequences generated from two logistic maps. Unlike classical image encryption schemes that adopt S-Box or permutation of the entire plain image, the diffusion property is satisfied using addition operations. The proposed scheme exhibits good performance on correlation coefficients (horizontal, vertical and diagonal), Shannon's entropy and NPCR (Number of Pixels Change Rate). Furthermore, simulation results indicate that its time complexity is 9.2 times more efficient than the fastest algorithm(Yang's algorithm).
