Secure strategy for OFDM-PON using digital chaos algorithm with fixed-point implementation.

The dynamical degradation problem is improved by introducing the transmitted data as a perturbation source. In our demonstration, aperiodic key streams are generated from a fixed-point chaos with its trajectory disturbed by the upstream data, and then used to encrypt the downstream data. A 7.64-Gbps encrypted OFDM signal is successfully transmitted over a 25-km standard single mode fiber. The experimental results indicate that the proposed scheme suggests an effective and promising solution to meet the demands for low implementation complexity and high security level.||URI:||https://hdl.handle.net/10356/139393||ISSN:||0733-8724||DOI:||10.1109/JLT.2018.2865222||Rights:||© 2018 IEEE.
