复合级联混沌的彩色图像加密算法
Image encryption algorithm based on compound cascade chaotic
摘要
Abstract
This paper analyses the current color image encryption algorithm based on chaotic system. In the process of color image chaos encryption,security is not perfect,and on this basis it puts forward a new kind of multiple pixel scram-bling based on cascade chaotic color image encryption algorithm.The algorithm adopts the composite of discrete chaotic system of the cascade of Kent-Logistic chaos and Henon,and combined with Arnold mapping and pixel permutation cut-ting of multiple pixel scrambling method,makes the image pixel value and pixel position scrambling diffusion,so as to achieve clear image information hiding ciphertext effect completely.Simulation experiments show that the algorithm not only can effectively resist choose clear(ciphertext)attack,statistical characteristics analysis,differential attack,but also has the advantages of good encryption effect and large key space.关键词
