基于状态观测器方法和Routh-Hurwitz判据,设计一类混沌系统的同步和保密通信的简单有效的方案,并分析系统的稳定性。通过设计状态观测器,使2个混沌系统保持同步,从而实现加密信号的再现。仿真结果表明,该方法在混沌同步及保密通信中具有同步速度快、系统精度高等优良性能。

Based on the state observer method and Routh-Hurwitz criterion, this paper designs a simple and effective method of a species of chaotic systems synchronization and secure communication, and analyzes its stability. Two chaotic systems can keep synchronized by designing the state observer, hence, recur the encrypted signals. Simulation results show that the proposed scheme has accuracy and high speed for chaotic synchronization and secure communication.
