Subject: Request for comments
NIST requests comments on two Draft publications for random bit generation: Draft SP 800-90B, Recommendation for the Entropy Sources Used for Random Bit Generation and Draft SP 800-90C, Recommendation for Random Bit Generator (RBG) Constructions. SP 800-90B specifies the design principles and requirements for the entropy sources used by Random Bit Generators and the tests for the validation of entropy sources. A list of questions relating to SP 800-90B is also provided for reviewers. SP 800-90B and the questions are available at http://csrc.nist.gov/publications/PubsDrafts.html. SP 800-90C specifies constructions for the implementation of random bit generators (RBGs). An RBG may be a deterministic random bit generator (DRBG) or a non-deterministic random bit generator (NRBG). The constructed RBGs consist of DRBG mechanisms as specified SP 800-90A and entropy sources as specified in SP 800-90B. SP 800-90A is available at http://csrc.nist.gov/publications/PubsSPs.html#800-90A. SP 800-90C is available at http://csrc.nist.gov/publications/PubsDrafts.html. Please send comments to firstname.lastname@example.org by December 5, 2012. For the comments on SP 800-90B, please put Comments on Entropy Sources in the subject line. For the comments on SP 800-90C, please put Comments on RBG Constructions in the subject line.
