Abstract:

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.

Key words: chaotic synchronization, state observer, secure communication
