Hao Zheng · Jisuanji gongcheng · 2012
Aiming at the problem of divide-and-conquer attacking on the low-dimensional chaotic system,a new image encryption algorithm based on multidimension chaotic system is proposed.Such as Arnold,Ushiki and 3D Lorenz map,on the basis of the research on different chaotic maps,it achieves the structure of more overall rounds of confusion stage and a single diffusion stage.It contains pixel confusion and the key stream,as well as the way of encryption operator generation.Experimental results show that the proposed algorithm can get excellent encryption effect,high security performance,and strong attack against ability.
