What makes it... WebApr 14, 2024 · The NIST SP 800-90 series [1][2][3] supports the generation of high-quality random bits for cryptographic and non-cryptographic use. The security strength of a random number generator depends on the unpredictability of its outputs. This unpredictability can be measured in terms of entropy, which the NIST SP 800-90 series …

WebDec 12, 2007 · The first step is to get a cryptographically random 32-bit integer. There’s a Random class provided by Microsoft in the System namespace (that you’ll use), but the level of entropy (randomness) is minimal if you rely only on that class. Instead, you’ll use the RNGCryptoServiceProvider namespace, provided in System.Security.Cryptography: WebAug 6, 2016 · A cryptographically secure RNG is unbiased. There's no reason to believe that a biased RNG would have independent events; unbiasing an RNG requires crypto, and assembling a biased entropy source and a CSPRNG is how you get a cryptographically secure RNG. – Gilles 'SO- stop being evil' Aug 5, 2016 at 21:28 Great answer, thanks.
WebSystem.Random類可能足夠好了: 從有限的數字集合中以相等的概率選擇偽隨機數。 所選擇的數字不是完全隨機的,因為使用確定的數學算法來選擇它們,但是出於實際目的它們是足夠隨機的。 Random類的當前實現基於Donald E.
