Test Study on Surrogate Data of Chaotic Encryption Communication System
-
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，为进一步利用非线性时间序列分析方法分析混沌保密系统提供了理论依据．Abstract: 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.
