摘要
生成算法对于动态口令的随机分布特性存在不利影响。文章提出了基于序列随机性检测对动态口令生成算法进行定量分析的思路,以RFC4226为对象设计了实验方案并进行实验,对实验结果进行了分析和总结,验证了方案的可行性,提出累加和测试项适合作为评估动态口令生成算法随机分布特性的指标。
The generation algorithms of One Time Password give negative but uncertain effects on random distribution characteristics. About the quantitative analysis of the effects, an idea based on sequence randomness test is given. An experiment with RFC4226 is designed and performed according to SP800-22. By analyzing the experiment data, the idea is proved available, and is suitable to estimate the effects.
