摘要
利用了R.Devany混沌理论构造了一种混沌动力系统,并用所生成的混沌序列对图像进行加密.由于混沌动力系统有很强的不可预测性,因此,混沌序列对图像加密能更好的抵御各种攻击.此方法具有加密速度快、安全性高特点.
In the paper, a chaotic dynamical system is constructed by using R. Devany chaotic theory. The image is encrypted with the chaotic sequence. From the chaotic dynamical system has stronger unpredictability, so encrypting the image by the chaotic sequence is able to resist all kinds of attacks. An example is given to illustrate the fast encryption speed and high security of the method through the kinds of the verifies.
