Image encryption algorithm Based on Logistic chaotic system and s- box scrambling

摘要：

Constructing Logistic function, with its resulting overwritten with random pixels on the image information, confusion and as a sub-key of the encryption algorithm. Introduction oftheFeistel network block cipher structure and AESS-boxin the matrix of image pixels scrambling. In this paper, we proposed an image encryption algorithm system which is based on Logistic chaotic. Design state sliding block and line shift, effectively confusing data and spread of key features. Simulation experiment and theoretical analysis proved that the algorithm can effectively resist brute force attack, statistical analysis and differential attack, with a good of cryptography features.
