We propose and demonstrate a physical layer security scheme via chaotic partial transmit sequence (PTS) technique in orthogonal frequency-division multiplexing passive optical network (OFDM-PON). A 4-D hyper chaos is employed to generate the chaotic partition information, the chaotic phase weighing factors in PTS as well as the chaotic training sequence for OFDM symbol synchronization, which provides...
Fiber optical network offers higher data rate and larger capacity transmission, however the security issues are becoming a big concern. Digital chaos is capable of providing a huge key space for data encryption in physical layer, to enhance network security during high-speed data transmission. We will review the recent progress on security enhancement via the implementation of digital chaos for high-speed...
