摘　　要：为了提供一种简便和有效的真随机数生成方法,通过分析环境噪声数据的统计特性,提出同余法和正负法将声音波形数据进行处理。去除声波数据的周期性、连续性、相关性,提取其随机性。同真随机数采集系统设计相关的电路噪声问题以及采集速度问题也作了讨论。用此思路构建的真随机数采集系统原型已经能够用来产生性能较佳的真随机数,证明了设计思路和处理方法的正确有效性。To provide a simple and effective way to generate real random numbers, by analyzing the statistical character of environmental noises, congruence method and positive-negative method are proposed to process the data of sound waves. Periodicity, continuity and correlation of sound data are wiped off and random icity is extracted. The problems of circuit noise and collecting speed concerning the design of the real random number collecting system are also discussed. A prototype system following this idea has obtained the capability to generate eligible real random numbers and the design and processing methods have been proved valid.
