资料介绍

混沌在非线性科学中是一个很重要的组成部分,由于它具有确定性、有界性、对初值的敏感性、长期不可预测性等固定特性,使其混沌理论及其应用研究获得了巨大的发展。在混沌保密通信、数据加密、流体混合等领域,成为大家普遍所接受的方法及其应用重点。由于混沌信号明显的宽带白噪声特点,可根据非线性动态系统产生并且很容易进行控制。动态系统的不同初始状态下,所产生的混沌信号相互之间不但正交且独立。因此,混沌信号在保密技术方面中得到了广泛的应用。

Chaos,with its fixed features such as certainty,bounded property,susceptibility to initial value,long-term unpredictability and so on,is a very important part in nonlinear science,letting the research on its chaos theory and application have a great progress,which becomes a common method and an applied focus in the fields of security communication in chaos,data encryption and fluid mixing. Due to the obvious characteristic of wide band white noise of the chaotic signal,it is easy to control according to the nonlinear dynamic system. Under different initial states of dynamic system,the generated chaotic signals are mutually independent and orthogonal.Therefore,chaotic signal has been widely used in security technology.
