Implementation and evaluation of a new unified hyperchaos-based PRNG

The use of rapid prototyping tools such as MATLAB Simulink and Xilinx System Generator becomes increasingly important because of time-to-market constraints. In this paper, we consider Xilinx System Generator for software simulation and real time implementation on FPGA circuit of a pseudo-random number generator (PRNG) based on unified hyperchaotic system. For this purpose, we propose a new PRNG with good randomness characteristics based on a novel conception where a parameter perturbation control to the input and a special function to the output are used in order to drive the unified hyperchaotic system to the PRNG. The design was implemented targeting a Virtex-5 FPGA device (XC5VFX70T- 1FFG1136).
