Chaos-based selected mapping scheme for physical layer security in OFDM-PON

摘要

A novel chaos-based selected mapping (SLM) scheme is proposed for physical layer security in OFDM-PONs, where a Hénon chaos map is employed to create a large key space for OFDM data encryption. The transmission performance is significantly improved due to the peak-to-average power ratio reduction in the SLM scheme. High quality 8.9 Gbit/s 16-QAM OFDM encrypted data transmission is demonstrated over a 20 km single-mode fibre.
