如何测试随机生成器 [英] How to test a random generator

问题描述

我需要测试随机产生数字的随机数生成器.如何确保生成的数字是随机的.

I need to test a random number generator which produces numbers randomly. How to make sure the numbers generated are random.

推荐答案

无论如何，您只能测试统计随机性，但这不能证明数字序列在密码学上是否强.对PRNG进行统计测试需要大量(10甚至100Gbytes)生成的比特.

You can only test statistical randomness anyway, and that does not prove whether the number sequence is cryptographically strong. Statistically testing a PRNG requires quite a lot (10 or even 100Gbytes) of the generated bits.

Dieharder是一个非常好的测试套件.

Dieharder is a very good testing suite.

TestU01也是众所周知的.

And TestU01 is also well-known.
