Modeling and analysis of chaos-modulated dual oscillator-based random number generators

This paper introduces a numerical model for the simulation of chaos-modulated dual oscillator-based random number generators. Random number generation method based on dual oscillator architecture is described. Developed model allows the estimation of the output entropy and bias as a function of design parameters, thus provides determination of these parameters for a continuous-time chaotic source appropriately. Numerical simulations are performed in order to address important design issues and simulation results, verifying the feasibility and the correct operation of the model, are presented. High-performance random number generators can be realized in the light of the numerical model.
