The real-time implementation is demonstrated using Field-Programmable Gate Array (FPGA) hardware with Xilinx System Generator (XSG), for secure orthogonal frequency division multiplexing (OFDM) transmission. Vivado software and Verilog programming language are used for the purpose of the real-time system design and the OFDM data transmission. An encrypted 1.-QAM OFDM data transmission and recovery are successfully carried out using FPGA. The multi-fold data encryption is achieved via the input data encryption using XOR, real and imaginary parts of QAM symbols encryption, where the chaotic sequences are generated by a hyper digital chaos. As a result, it provides a key space of ~1. 22 to enhance the confidentiality of OFDM data transmission.
This paper proposes a multi-fold optical frequency hopping (FH) scheme based on hyper digital chaos. The multi-fold data encryption is achieved by the incorporation of chaotic sequences into traditional FH scheme, whe...

This paper proposes a multi-fold optical frequency hopping (FH) scheme based on hyper digital chaos. The multi-fold data encryption is achieved by the incorporation of chaotic sequences into traditional FH scheme, where a hyper digital chaos is implemented to generate the optical carrier frequency, FH rate as well as the available frequency set respectively. As a result, a huge key space of 1. 58 is provided in the proposed multi-fold data encryption. The performances of data transmission and security enhancement of the proposed FH scheme are simulated and analyzed in details.
