摘　　要：随机数的质量在一定程度上决定了信息安全系统的性能,利用电源噪声随机性特性,设计了一种基于现场可编程门阵列(Field Programmable Gate Array,FPGA)的高速随机数发生器,并详细讲述了方案的原理、芯片的选型以及实现的电路图,然后开展数据的随机性和自相关性测试。结果表明,由电源噪声放大后再进行模/数转换得到的高速随机数发生器,可以获取随机性能好、速率较高(1 Gbit/s以上)的随机数,并且速率可扩展,方案实现简单、成本较低。The quality of random numbers determines the performance of information security systems to some extent.Taking advantage of the good randomness characteristics of power supply noise,a high-speed random number generator based on FPGA(Field Programmable Gate Array)is designed,and the principle of the scheme,the chip selection,and the circuit implementation diagram are described in detail.Then,the randomness and autocorrelation tests of the data are carried out.Test results indicate that the highspeed random number generator obtained by amplifying power noise and then performing analog-to-digital conversion can obtain random numbers with good randomness and high speed(over 1Gbps),and the speed is scalable.The implementation of the scheme is simple and the cost is low.
