提出了一种用于增强正交频分多址无源光网络（OFDMA-PON）物理层安全的混沌星座变换（CCT）技术。该方法采用一种改进的猫映射，其控制参数由交叉混沌映射产生。此外，提出了一种导频辅助的安全密钥协商方案，以确保安全密钥在发射机和接收机之间安全地分配。在25 km的标准单模光纤上实现了18.86 Gb/s的基于16进制正交幅度调制的加密OFDM信号传输。实验结果表明，提出的CCT技术和导频辅助的安全密钥协商是有希望的物理层安全增强未来的OFDMA-PON。
This paper proposes a chaotic constellation transformation (CCT) technique for physical-layer security enhancement in orthogonal frequency-division multiple access based passive optical networks (OFDMA-PONs). The CCT is performed by using an advanced cat map whose control parameters are generated by a cross chaotic map. Moreover, a pilot-aided security key agreement scheme is proposed to ensure that the security keys are securely distributed between the transmitter and receiver. A 18.86 Gb/s encrypted 16-ary quadrature amplitude modulation based OFDM signal transmission over a 25 km standard single mode fiber is experimentally demonstrated. The experimental results show that the proposed CCT technique and the pilot-aided secure key agreement are promising for physical-layer security enhancement in future OFDMA-PONs.
