基于小波变换域混沌加密与循环移位的改进图像加密算法
Chaotic encryption in wavelet transform and cycle shift based improved image encryption algorithm
摘要
Abstract
Traditional chaotic image encryption algorithm is based on the spatial domain of the image,leading to a low key sensitivity and difference performance,this paper proposed a chaotic encryption in wavelet transform and cycle shift based im-proved image encryption algorithm to overcome that problem.Firstly,it generated different keys according to the origin ima-ges,it transformed the image pixels were cycle shifted with the keys;then it transformed the image into wavelet domain;last-ly,it performed 2D chaotic map to the image,and substituted and diffused the origin code.Experiments results show that,the proposed algorithm has a good performance in statistical performance,robustness,key sensitivity performance.关键词
