主 题：Color image encryption DNA encoding lorenz system rossler system SHA-2
摘 要：Nowadays,high-resolution images pose several challenges in the context of image *** encryption of huge images’file sizes requires high computational *** encryption techniques like,Data Encryption Standard(DES),and Advanced Encryption Standard(AES)are not only inefficient,but also less *** to characteristics of chaos theory,such as periodicity,sensitivity to initial conditions and control parameters,and ***,the characteristics of deoxyribonucleic acid(DNA),such as vast parallelism and large storage capacity,make it a promising *** paper presents an efficient color image encryption method utilizing DNA encoding with two types of hyper-chaotic *** proposed encryption method comprises three *** first step initializes the conditions for generating Lorenz and Rossler hyper-chaotic maps using a plain image Secure Hash Algorithm(SHA-256/384).The second step performs a confusion procedure by scrambling the three components of the image(red,green,and blue)using Lorenz hyper-chaotic ***,the third step combines three approaches to encrypt the scrambled components for diffusion:DNA encoding/decoding,addition operation between components,and XORing with Rossler hyper-chaotic *** simulation results indicate that the suggested encryption algorithm satisfies the requirements of *** entropy value of confusion and diffusion is 7.997,the key space is 2200,and the correlation coefficient is nearly *** efficacy of the proposed method has been verified through numerous evaluations,and the results show its resistance and effectiveness against several attacks,like statistical and brute-force ***,the devised algorithm vanquishes other relevant color image encryption algorithms.
