摘要
为了克服常见混沌映射在生成伪随机数过程中出现的缺点,在分析了常用混沌映射方法优缺点的基础上,提出了一种基于Logistic混沌映射与Tent混沌映射的组合混沌映射算法。经过分析验证表明该算法生成的伪随机数具有更好的随机性。
In order to overcome the disadvantage of the common chaotic maps for generating pseudo-random number, this paper has analyzed advantages and disadvantages of commonly used methods of chaotic map, and then proposes a hybrid algorithm based on Lo- gistic chaotic mapping and Tent chaotic mapping. The algorithm has a better performance in generating pseudo-random number through analysis and testing.
