摘要
基于超混沌信号的非周期性和不收敛性,提出了利用超混沌信号对活动图像进行加密的一种新方法,详细地论述了加密矩阵的实现。用产生的加密矩阵随机地改变每一帧图像的每一个像素,并利用图像置乱变换技术来实现对活动图像加密的目的。实验结果表明此方法是可行的。
In this paper,based on non -periodical motion and non -convergence of hyperchaos,a new method for encryption of active images utilizing hyperchaos is proposed and the implemention of encryption matrix is demonstrated in detail.In order to realize encryption of active images,every pixel of every frame image is randomly changed according to encryption matrix,simultaneously scrambling transformation technique is used.Experimental results indicate feasibility of this method.
