DOI: 10.1109/lpt.2018.2853155
Abstract: We propose and experimentally demonstrate a novel real-valued chaotic orthogonal matrix transform-based encryption scheme for improving the physical-layer security in fast orthogonal frequency-division multiplexing (fast-OFDM) passive optical network. Chaotic orthogonal matrices generated by a four-dimensional… read more here.
