An Image Encryption Algorithm Based on Multiple Chaotic Mapping
Wei Liu · Jisuanji gongcheng · 2012
This paper has brought forward a way of image encryption algorithm based on multiple chaotic maps for improving the safety of image information.This algorithm regards the chaotic sequence and the pixel coordinate of the color image as two points in space,using the formula of the distance of two points in space to generate the sequences to encrypt the image.Simulation results demonstrate that the algorithm is easy to carry out,has a strong sensitive effect on the key,its key space is enough large,and it has very uniform pixel-value distribution.
