Image Encryption Based on Pixel Shuffling with 3D Chaotic System
Asia Mahdi Naser Alzubaidi [3]
Abstract: In recent years; with the fascinating development of internet technologies and wireless communication networks such as computer and mobile networks. all types of multimedia data such as digital image; Audio; text and video can be reached in easily way over internet. Due to this; cryptographic techniques are required to accomplish a sufficient level of security; integrity; confidentiality as well as; to prevent unauthorized access of important information during data storage and transmission. To meet this challenges; a novel and efficient color image encryption chaos-based scheme has been suggested in order to confuse the relation between adjecent pixels by alter the position of image pixels using block image scrambling by iteratively dividing it to sixteen blocks and rotate each one in to clockwise direction with 90 angle. then; apply 2D Arnold cat map with row_colunm wise methods to make more distortion of the relationship among connected pixels of original image by hide the statistical structure of pixels. The second part of proposed method is to diffuse the relation between plain and encrypted images by change the gray scale value of original image pixels using 3D logistic chaotic function. The presented encryption algorithm as mentioned in this work; has been tested and analysis on some color images and the results showed a significant security and validity to resistance the statistical and differential attacks such as frequency analysis attack. Moreover the encrypted images have entropy near to ideal rate and correlation coefficients close to 0 value. the experimental results and numerical analysis demonstrates the security; flexibility; correctness; effectiveness; Reliable and robustness of the proposed cryptosystem.
