| 摘 要： | 针对单混沌系统因计算机有限精度效应产生的混沌退化问题，提出了一种多级混沌映射交替变参数的伪随机序列产生方法。该方法基于一维Logistic映射和二维Henon映射，用交错变参的Logistic映射的混沌迭代值的汉明重量来控制Henon映射输出的混沌迭代分量。生成序列通过仿真表明，符合Golomb三个随机性公设要求及局部随机性统计检验要求，可作为密钥流序列应用到加密体制中。

| Abstract: | Due to chaos degeneration question caused by computer limited precision in one chaos system, this paper proposed a method of pseudo-random sequence generation with alternating parameter of multistage chaos mapping. Based on one-dimensional Logistic mapping and two-dimensional Henon map, the system output was one component of Henon chaotic iterative values, which was controlled by the Hamming weight of Logistic chaotic iteration value with alternating parameter. Computer simulation results show that, the sequences generated by the chaos system can pass the three randomness testing of Golomb and partial randomness testing, and can be used as key stream in the encryption system. |
