Abstract

A secure scheme based on Rubik’s Cube (RC) transformation algorithm with low calculation complexity is proposed and experimentally demonstrated in the orthogonal frequency division multiplexing passive optical network system (OFDM-PONs). The RC transformation algorithm is adopted to generate encryption key stream for symbol substitution, and the chaos is utilized to control the RC transformation. An experiment with 7.64Gbps 16-quadratureamplitude- modulation (QAM) encrypted OFDM data are successfully transmitted over 25km standard signal mode fiber (SSMF). The experimental results indicate that the proposed scheme is an effective and promising method for physical-layer secure optical communication to meet the demands for low implementation complexity and high security performance.
