中文摘要：

针对一类非线性金融系统,利用Lyapunov稳定性理论,设计了一个控制器,使得驱动系统和响应系统很好的达到了同步.然后基于该同步,建立了保密通信方案：把有用信号和混沌变量相加成为混沌传输信号,在接收端信息信号被有效复原.数值仿真结果表明：通信方案的有效性和可行性.

英文摘要：

This paper aimed at chaos synchronization of a kind finance system and its application in secure communication.To begin with,based on the Lyapunov stability theory,a controller,which makes driving system and response system realize synchronization very well,was designed.Moreover ground on synchronization,secure communication was investigated.Simulation results indicated that the communication scheme was feasible and effectual.
