Chaotic index modulation and subcarrier intra-block-inter-block shuffling for secure CO-OFDM-PON based on a hybrid 4D chaos
{{output}}
In this paper, a four-dimensional (4-D) encryption scheme with chaotic index modulation (IM) and subcarrier intra-block-inter-block shuffling is proposed to enhance the physical layer security of coherent orthogonal frequency division multiplexing passive opti... ...
