Abstract
This work develops a solution for simultaneous physical layer security enhancement and peak-to-average power ratio (PAPR) reduction for orthogonal frequency division multiplexing passive optical network (OFDM-PON) systems. The encryption is carried out within the subcarriers with the help of three-dimensional (3-D) chaotic cat map. Experimental results demonstrate that the OFDM-PON system under the protection of the proposed technique is high sensitive to the secret key, invalid optical network units cannot obtain any useful information from the ciphertext. Besides, the PAPR of the OFDM symbols has also been significantly reduced, and hence the system is more robust against various nonlinear disturbances.
