Abstract :
In this paper we propose a novel digital secure communication scheme based on sporadic coupling chaos synchronization. Compared with a conventional chaos masking method, it has higher noise-resistibility, better security and frequency efficiency, etc. Simulation results illustrate the effectiveness and efficiency of this method. Finally, we analyze factors which affect system ability and give some conclusions
