为了提高相干光正交频分复用（CO-OFDM）无源光网络系统的安全性，本文提出了一种基于布朗运动的混合符号替换和交错技术。利用混沌映射生成布朗运动参数。采用基于布朗运动的混合符号替换和符号交错对OFDM信号进行加密。在我们的演示中，36.67 gb /s的加密OFDM信号在100公里的单模光纤上实验传输。实验结果验证了该技术在物理层安全增强的co - ofdm接入网系统中的应用前景。
This letter proposes a hybrid symbol substitution and interleaving technique based on Brownian motion for security improvement in the coherent optical orthogonal frequency division multiplexed (CO-OFDM) passive optical network systems. The parameters of Brownian motion are generated by using the chaotic maps. Brownian motion-based hybrid symbol substitution and symbol interleaving are used to encrypt the OFDM signals. In our demonstration, 36.67-Gb/s encrypted OFDM signals are experimentally transmitted over a 100-km single mode fiber. Experimental results verify that the proposed technique is promising for physical-layer security-enhanced CO-OFDM-based access network systems.
