Description
Summary: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.
