Abstract-The use of digital images in most fields of information technology systems makes these images usually contain confidential information. When these images transmitted via the Internet especially in the Cloud, it becomes necessary to protect these images in a way that ensure putting the confidential information that are contained far away from the attackers. A proposed image encryption technique has been presented in this work. This technique used a secret key that is extracted from the image content itself. Therefore, there is no need to find a secret channel to exchange any key where, sender and receiver authenticate each other with regards to a shared secret key extracted from the image. The technique constructs its secret key that is used to encrypt the image, based on the entropy values of a set of randomly selected blocks from the image itself. Vairous experiments have been conducted to evaluate the strength and performance of the technique. The experimental results shows that the proposed technique can be used effectively in the field of image security to protect and authenticate images.

Currently no one can deny the importance of data protection, especially with the proliferation of hackers and theft of personal information in all parts of the world .for these reasons the encryption has become one of the important fields in the protection of digital information.This paper adopts a new image encryption method to overcome the obstacles to previous image encryption methods, where our method will be used Duffing map to shuffled all image pixels ,after that the resulting image will be divided into a group of blocks for perform the shuffling process via Cross Chaotic Map.Finally, an image called key image was created by using Quadratic number spirals which will be used to generate numbers of polynomial equations via Lagrange interpolation to perform pixel diffusion.Simulations have been accomplished in order to evaluate the effectiveness of suggested technique, the Experimental results demonstrate that the proposed method can supply sufficient security for the confidentiality of images.

“…Due to some intrinsic features of image data, such as bulk data capacity, high redundancy and high correlation among adjacent pixels, traditional cryptosystems, for example, International Data Encryption Algorithm(IDEA), Data Encryption Standard (DES), and Advanced Encryption Standard (AES), are unsuitable for image data encryption [1][2][3]. It is well known that chaos theory has many unique characteristics, such as ergodicity, pseudo randomness, sensitivity to initial conditions and control parameters [4], and these characteristics meet the requirements of diffusion and mixing in the sense of cryptography.…”

Abstract:The composite discrete chaotic system (CDCS) is a complex chaotic system that combines two or more discrete chaotic systems. This system holds the chaotic characteristics of different chaotic systems in a random way and has more complex chaotic behaviors. In this paper, we aim to provide a novel image encryption algorithm based on a new two-dimensional (2D) CDCS. The proposed scheme consists of two parts: firstly, we propose a new 2D CDCS and analysis the chaotic behaviors, then, we introduce the bit-level permutation and pixel-level diffusion encryption architecture with the new CDCS to form the full proposed algorithm. Random values and the total information of the plain image are added into the diffusion procedure to enhance the security of the proposed algorithm. Both the theoretical analysis and simulations confirm the security of the proposed algorithm.
