随着下一代网络对大容量、宽带宽的需求日益增加，ROF（光纤无线融合）是一种有前景的技术，但ROF技术面临着窃听与泄漏等信息安全问题。本课题对混沌非线性理论在高速ROF系统安全应用进行研究，拟从理论和实验探索：1)研究混沌控制自适应毫米波的方法，探索ROF毫米波信号的保密措施；2)研究高效混沌信号加密OOFDM超密集波分复用光纤无线融合系统，研究色散及非线性效应对各通道混沌掩盖信号的解调机制；3)研究OOFDM-ROF系统的物理层加密算法以及新型混沌密钥源的产生方法，并寻求混沌降PAPR的普适算法；4)研究Polar编码与混沌加密结合的OOFDM-ROF系统，探索极化与混沌加密系统的构成及其安全有效的译码方法。本项研究成果对于提高ROF系统的安全性和可靠性将提供强有力的保证，具有重要的科学意义和应用价值，同时也将为我国大容量光纤无线融合系统安全接入及实施奠定理论与实验基础。

With the increasing demand of next generation network for large capacity and wide bandwidth, radio-over-fiber (ROF) is a promising technology, but ROF technology faces a series of information security problems. In this research, the basic theoretical and experimental study on the application of chaotic nonlinear theory in high-speed ROF system will be carried out in order to improve the performance and safety of the system, we expect to explore the following questions: 1) explore the method of chaos controlling adaptive millimeter wave and the security measures of millimeter wave signal; 2) study the encryption technique for the OOFDM in UD-WDM transmission system, and study the demodulation mechanism of dispersive and nonlinear effects on the chaotic masking signals of each channel; 3) study the generation method of the new chaotic key source and the physical layer encryption algorithm of OOFDM system, and develop a chaos-based PAPR reduction universal algorithm in OOFDM encryption system; 4) study the influence of Polar channel coding technology of chaotic OOFDM-ROF system, and explore the secure and effective decoding method of the structure. The study outcomes will provide a strong guarantee to improve the safety and reliability of OOFDM communication system, and have important scientific significance and application value. Moreover, it will benefit to large capacity ROF security access in our country and provide the theoretical and experimental foundation.
