摘　　要：对文献[5]中提出的混沌加密系统进行仿真与分析,通过分析可知该加密系统中所采用的混沌系统在随机性上有所欠缺.在此基础上,提出了将Chebyshev混沌系统应用到该混沌加密系统中,并对改进后的混沌加密系统进行仿真与分析,可知该混沌系统具有良好的随机性.将混沌系统应用到数码防伪技术中,使密钥空间增大,使破译的难度增强,使商品在市场流通中具有更强的防伪性能,可以很好地弥补了数码防伪技术所存在的不足.Base on the literature [5] 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.
