The Application of Chaotic Systems in Image Encryption

Tan Guo-lv

Abstract

Studied the current image encryption algorithms based on chaos system broadly,found that the 1D chaotic image encryption had serious drawbacks,such as the low complexity,the poor security.So a image encryption algorithm based on 1D chaotic system and 3D chaotic system is designed.In this paper,the value that produced by chaos function is used to be the initial value of the 3D chaotic system,then,the result is used to encrypt the image.At last,analysed its security and sensitivity,and programmed to implement.
