基于混沌映射的图像加密算法
Image Encryption Algorithm Based on Chaotic Mappings
摘要
Abstract
This paper designs a new kind of image encryption algorithm which uses two Logistic systems. The auxiliary key m is obtained by a certain line data of the changed image matrix. The initial values of two Logistic mappings are modified by the key in. The Logistic mappings are used to generate the encryption sequences which are used to encrypt with every pixel of the image. Theoretical analysis and simulation results show the new algorithm not only has better sensitivity and very uniform pixel-value distribution, but also is simple and easy to achieve.关键词
