摘　　要：本文针对混沌法产生的伪随机数序列统计性能不佳的缺陷,提出了一种将Logistic混沌映射和无限折叠混沌映射进行组合的伪随机数发生器新方法。计算机仿真结果表明,此方法比单个的Logistic映射伪随机数发生器或无限折叠混沌映射伪随机数发生器具有更优良的统计性能。The pseudorandom number sequences generated by the chaotic methods usually have unsatisfactory statistical performance.To solve this problem,this paper presents a novel pseudorandom number generator with uniform distribution,which combines the logistic chaotic map and the chaotic map with infinite collapses.Both computer simulations and performance analyses results show that the proposed method has much improved statistical performances than the logistic chaotic map or the chaotic map with infinite collapses without combination.

关 键 词：伪随机数发生器 混沌映射 统计检验
