Efficient Real-Time Key Generation for IoT Using Multi-Dimensional Chaotic Maps

The paper presents a new approach for triple key generation techniques with Henon, Lozi and Duffing chaotic maps in FPGA. Three key streams generated by XORing chaotic maps with pseudo random number generators, the results of XORing PN1 with PN2 is called gold code generator. The algorithm was built in embedded Xilinx System Generator tool (XSG) and the results were validated using MATLAB/SIMULINK environment. NIST, Normality and Dieharder test randomness tests were employed for key streams and verified as the best randomness in comparison with recent work.
