一个新的四维混沌吸引子及其信息加密研究

摘要

In order to obtain more complex chaotic signal source novel, this paper proposes a new four-dimensional chaotic system, the attractor shape is similar to the image, " four phoenix toward the sun" ,and the use of the chaotic signal to achieve the signal encryption and image encryption method, and the number of iterations and the chaotic signal using addition and subtraction means to set the password for the encrypted information to provide a new method.%为了获得更为复杂新颖的混沌信号源,提出了一个新的四维混沌系统,其吸引子形状类似于图像"四凤朝阳",并且利用该混沌信号源来实现信号加密和图像加密的方法,并利用迭代次数和混沌信号的加减手段来设置密码,为信息加密提供了一种新方法.
