基于混沌同步技术和自适应观测器,设计一种保密通信系统.使用Lorenz混沌系统对原信号进行加密,利用自适应观测器对加密信号进行解密,以实现保密通信.仿真实验表明,该系统的算法简单、响应速度快,能实现响应系统与驱动系统的同步,提高混沌保密通信的质量和安全性.%Based on chaotic synchronization and self-adaptive observer, this paper presents a new secure communication system. By using Lorenz chaotic system and self-adaptive observer to code and decipher the original information, the objective of chaotic secure communication is realized in this system. Simulation experimental results verify that it is a simple, feasible and effective method to the synchronization of response system and drive system, and it can improve the quality and safety of chaotic secure communication.
