“…The proposed method was tested on a group of colored images: Lena, Baboon, Barbara, and Pepper of size (256×256). In the permutation stage, we used three registers of different (29,31,33) and different (13, 7, 2), (3, 2, 1), (22, 13, 11,) respectively, and each register had a unique initial value(seed). The number of sequences bits required to generate each number depended on the number of pixels in one-half of the image size.…”

“…In the begging, the inputting color image is divided into two equal parts (upper UP and lower LW) with size Sk. Second, using LFSRs that comprise three registers with different lengths (29,31,33) and different taps (2,7,13), (1,2,3), (11,13,22), respectively, key K is generated that contains non-repetitive random numbers with size Sk. The same key is used to redistribute the locations of the pixels in each part.…”

Protecting information sent through insecure internet channels is a significant challenge facing researchers. In this paper, we present a novel method for image data encryption that combines chaotic maps with linear feedback shift registers in two stages. In the first stage, the image is divided into two parts. Then, the locations of the pixels of each part are redistributed through the random numbers key, which is generated using linear feedback shift registers. The second stage includes segmenting the image into the three primary colors red, green, and blue (RGB); then, the data for each color is encrypted through one of three keys that are generated using three-dimensional chaotic maps. Many statistical tests (entropy, peak signal-noise ratio (PSNR), mean square error (MSE) and correlation) were conducted on a group of images to determine the strength and efficiency of the proposed method, and the result proves that the proposed method provided a good level of safety. The obtained results were compared with those of other methods, and the result of comparing confirms the superiority of the proposed method.

Cryptography is a main item to generate confidence and empower services in the digital technology, while Steganography has vastly expanded in digital medias. Although developing these technologies hackers has established new methods to hack confidential information. To overcome these challenges, we proposed algorithm that encrypts a message by using DNA encryption algorithm, then multiply the output by a factor then compress the multiplying message by using GZIP algorithm, the last stage is hiding a compressed message in (LSB) image pixels. By using image measures such that PSNR, MSE, SSIM, NPCR, UACI and the ratio of data compression up to 75% where reduced the image difference, we obtained a good result when we combined these technologies. This work contributes to reducing the risk of information breach when sending and receiving confidential information between parties.

“…The logistic map [23] is among the simplest nonlinear chaotic maps and is therefore of particular interest to researchers. In 2018, a one-dimensional logistic map together with another chaotic map was involved in the generation of a key sequence for encrypting an image [29]. In 2019, a three-dimensional logistic map was modified to be the first step of the proposed image encryption algorithm to generate keystream by it [20].…”

To prevent sensitive images shared on social media from being stolen, researchers are seeking to find and innovate image encryption algorithms. Since attackers attempt to exploit it to access encrypted images, the problem of generating keys as the first stage of any encryption algorithm is regarded as a critical problem. This issue was dealt with in this paper through the use of the logistic map. This map must be calculated using specific conditions and special parameters to maintain its chaos. The Diffie-Hellman key exchange algorithm was modified to address this problem since the shared keys now consist of a 16-element vector. The first two elements will be used for a logistic map. The entire vector was used to create a self-invertible matrix. The encryption level entails two operations: the first is matrix multiplication with a vector, and the second is a bitwise XOR operation between two matrices. A proposed encryption algorithm is capable of producing encrypted images that are challenging to decrypt through the use of stringent security tests. The outcomes of each test show how well the proposed encryption algorithm performs compared with other algorithms and how to resist the attacks.
