摘要：

The theorem of chaos synchronization has many excellent characteristics and wide application prospect. Because the discrete components of the analog circuit are susceptible to environmental temperature and humidity, the continuous chaotic synchronization system is difficult to achieve in secure communication engineering. Based on the current large-scale digital logic circuit applications, many digital communication synchronization requirements are presented. In this paper, it is proved that that stability principle of the discrete system of Euler method, which is based on the design of discrete synchronous communication system. Three discrete synchronization methods for continuous chaotic systems with simple structures and easy to be implemented by engineering are designed, including discrete chaotic synchronization methods with driving-response, active-passive and self-adaptive methods. And through strict mathematical derivation proves its synchronization system can achieve asymptotically stable. In addition, A discrete chaotic secure speech concealment communication system based on self-adaptive synchronization is designed. The confidentiality and stability of the system is proved by relevant simulation experiments, which promotes the synchronization theorem and engineering application of chaotic secure communication. © 2020, Taiwan Ubiquitous Information.
