Recommendation for Random Number Generation Using Deterministic Random Bit Generators (Revised)



Elaine B. Barker, John M. Kelsey


[Superseded by SP 800-90A (January 2012):] This Recommendation specifies mechanisms for the generation of random bits using deterministic methods. The methods provided are based on either cryptographic hash functions, block cipher algorithms or number theoretic problems. [Supersedes SP 800-90 (June 2006):]
