| 摘 要： | 利用计算机系统中最常见的按键和鼠标消息作为随机源，采用安全散列算法（SHA-1）中的散列计算方法作为“搅拌”函数把收集到的随机源添加到随机池中，构造了一种产生伪随机序列的方法，并对产生的随机序列按照FIPS140-2中的标准进行了测试。结果表明，这种伪随机序列的生成方法可以应用于密码系统中。

| Abstract: | Utilizing the common keystroke and mouse moved messages of PC as source of randomness, and applying the hash function of SHA-1 as mixing function to combine the collected source to the pool of randomness, this paper constructs a pseudorandom sequence generator. The generated sequence is tested according to the standard of FIPS 140-2 statistical tests for randomness. The results of test indicate that this generator can be applied in cryptography. |
