扰动下一类超混沌系统的同步及其在保密通信中的应用

Synchronization of a class of hyperchaotic system in the presence of perturbation and its application to secure communication

本文基于状态观测器方法,在扰动存在的情况下,对一类超混沌系统的同步及其在保密通信中的应用问题进行了研究。研究表明,本文所给的方法克服了扰动对系统同步所造成的影响,使得系统保持着良好的同步。另外,本文考虑的超混沌系统,对保密通信系统有着较高的保密性,因此本文的方法在实际中更加可行。

In this paper, based on state observer, the synchronization of a class of hyperchaotic system and its application to secure communication are considered in the presence of perturbation. The result shows that the proposed method can overcome the perturbations influence on synchronization of hyperchaotic system, and make the system keep synchronous well. Meanwhile, the considered sysem is hyperchaotic that means the communication system is more secure. Therefore, the proposed method is more feasible in practical communication application.
