Image Encryption Algorithm Based on Improved Chaotic Cat Maps
Jiasheng Liu · Jisuanji gongcheng · 2007
Chaos is widely used in image encryption because of its high sensitivity to initial conditions and parameters and its generated chaos series without circle and of pseudo stochastic.An image encryption algorithm based on improved chaotic cat maps is proposed.In this method,the image is encrypted by diffusion function and improved chaotic cat maps,which can encrypt image not only based on disordering the positions of image pixels but also based on changing image pixels’ value,thereby significantly increasing the resistance to statistical attacks.The method is proved to work well.
