Abstract

A physical layer security enhanced orthogonal frequency division multiplexing (OFDM) passive optical network based on dimension-transformed chaotic permutation is proposed and experimentally demonstrated. In this scheme, a large key space is obtained by multidomain jointed Rossler permutation, and the corresponding complexity scale caused by multidomain encryption can be reduced through dimension-transformed permutation. An experiment with 10.61-Gb/s encrypted optical OFDM access system is performed to demonstrate the proposed method.
