Realization of Finite Precision Chaotic Systems via Perturbation of Chaotic Sequences

A concept of perturbing the values of variables in digital chaotic system is studied.In this paper,an approach to realize finite precision chaotic systems via perturbation of chaotic sequences is presented.After being perturbed,chaotic system can generate chaotic binary sequences with uniform distribution and with statistic properties invulnerable to cryptographic analysis.The simulation result shows that the perturbing concept is feasible.
