摘要
基于已有类Chen系统,通过引入三次项的方式构造新类Chen混沌系统。将已有类Chen系统与本文构造的类Chen系统进行级联,设计基于级联系统的混沌随机数发生器,并讨论不同随机数序列后处理方法。结果表明:含三次项的类Chen系统呈典型的混沌特征,具理想的最大Lyapunov指数、更多的平衡点和更复杂的结构;基于级联系统的混沌随机数发生器生成的随机数序列通过NIST检验,证明了该随机数生成方法的有效性。
Based on the existing Chen-like system,a new Chen-like chaotic system was constructed by introducing a third term.The existing Chen like system was cascaded with the Chen like system constructed.The Chaotic random number generator based on the cascade system was designed,and the post-processing methods of different random number sequences were discussed.The results show that the new Chen-like system with cubic terms presents typical chaotic characteristics,with ideal maximum Lyapunov exponents,more balance points and more complex structures.The random number sequences generated by chaotic random number generators based on cascaded systems pass the NIST test,which proves the effectiveness of the random number generation method.
