Abstract: Base on the literature5 is proposed on the chaotic encryption system simulation and analysis,which was lacked in the randomness.On this basis,the Chebyshev chaotic applied to the chaotic encryption systems and that simulation and analysis of its improved were investigated.The results show that well randomness.If the chaotic systems applied to anti-counterfeiting technology for digital,the key space of algorithm will be bigger and the goods process of commodity circulation has a stronger function of anti-counterfeiting. This can be making up for insufficiency of the anti-counterfeiting Technology for Digital.
