基于蔡氏電路的混沌保密通信研究

摘要：通過對混沌理論研究，對電路產生混沌信號進行了分析設計。同時基于蔡氏電路構建了混沌保密通信系統，并利用multisim軟件進行了仿真實驗。仿真結果表明，在發送端與接收端傳送一個疊加混沌信號的信息信號可以實現高質量的保密通信。 敘詞：混沌 蔡氏電路 混沌保密通信 Abstract：By studying on characteristics of chaos, we designed and analyzed the circuit how to produce chaos. At the same time, we constructed the chaotic secure communication system based on chaotic circuits, and made simulative experiments by Multisim.Simulation results show that, transfering information signal mixed with chaos signal between the sender and the receiver can achieve high quality secure communication.
