摘要：
The ever increasing growth of users and network capacity makes the security of passive optical networks (PON) an issue of great concern. In this paper, we present a novel work to enhance the physical layer security for wavelength division multiplexing orthogonal frequency division multiplexing PON. Elliptic curve with Diffie-Helman key exchange protocol is employed to derive a session key for Advanced Encryption Standard algorithm at optical line terminal and optical network units to provide secure communication. Encryption is applied on partial data of I/Q channel in order to reduce the computational time. Successful transmission of 16-Quadrature Amplitude Modulation encrypted OFDM signals at a distance of 100 km is demonstrated within the limits of peak to average power ratio value.
