| 摘 要： | 提出并实现了一种用作数据随机性分析的计算机辅助系统，利用随机过程的理论将话路噪声采集作为随机变量，并以文本文件的方式存储，通过对其进行一、二阶数理统计特征计算和Monbit及Runs测试，可完成对数据文本文件的随机性分析。在噪声源、密码编码算法的设计时有一定的应用价值。对电话线路上噪声的随机性分析实验表明，话路噪声是Golomb公设下随机的。

| Abstract: | A computer-assisted system for analyzing randomness of data flows is designed and implemented in this paper. According to theory of stochastic process, phone line noise is collected as a random variable and is stored in the form of text files in computers. By calculating one order and second order numerical statistics characters of the random variable, and by performing Monbit test and Runs test, the system can be used to ana-(lyze) randomness of data from text files, so it has definite application value in design of noise source and cryptogram arithmetic to verify the randomness of noise sources and disordered code flows. An experiment of line noise analysis shows that the phone line noise is stochastic in Golomb conditions. |
