摘　　要：提出了一种基于电力线信道噪声的真随机数发生器的设计,即通过对电力线信道上的噪声采样的方法来产生随机数。使用EAX加密算法作为后处理算法,消除由于外部干扰产生的偏差和自相关性。通过理论分析和实验验证,可以弥补现有常用真随机数生产法的不足,获得分布均匀、相对独立的随机数。A design of true random generator based on the noise of power line is proposed, which uses a sampling method of noise of the power line channel to generate random numbers. Meanwhile, use the EAX encryption algorithm as a post-processing algorithm to eliminate the deviation and auto- correlation by external interference. With theoretical analysis and experimental verification, this method can make up the shortcomings of existing meth- ods and result in evenly distributed as well as relatively independent random numbers.
