摘要
伪随机数发生器(Pseudorandom Number Generator,PRNG)是密码学应用系统的一个重要组成部分.本文利用线性同余发生器(Linear Congruential Generator,LCG)、流密码算法RC4和密码学Hash函数,构造了一种基于软件实现的组合式伪随机数发生器.该伪随机数发生器可以快速生成伪随机数列并且从理论上证明了产生的数列具备不可预测性.同时,采用美国国家标准和技术研究院(National Institute of Standard Technology,NIST)发行的随机性测试包对该新构造的伪随机数发生器所产生的序列进行统计测试.实验结果显示,该新构造的伪随机数发生器产生的序列能够很好地通过各项测试,可以应用于信息安全领域.
Pseudo-random number generator( PRNG) is an important part of cryptography application system. This paper constructs a combined pseudo-random number generator based on software using linear congruential generator( LCG),stream cipher algorithm RC4 and cryptographic Hash function. This pseudo-random number generator can quickly generate pseudo-random numbers and theoretically proves that the resulting sequence is unpredictable. At the same time,statistical tests were performed on the sequences generated by the newly constructed pseudo-random number generator using a randomness test package issued by the National Institute of Standards and Technology. Experimental results showthat the newly constructed pseudo-random number generator can pass all tests well and can be applied to the information security field.
