摘要
运用非线性检验技术中的替代数据方法 ,验证了混沌系统维数越高 ,保密性越强的理论 ,同时指出在欠采样间隔情况下 ,系统具有更强的保密性 。
In this paper, the author uses the surrogate data method to validate that the higher the system dimension is, the stronger the security of the system is. And it is proposed that large sampling interval is helpful for improving the security of the chaos secure communication, which provides the theory basis for further study of the chaotic system.
