Abstract: 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.
