NIST invites comments on the second draft of Special Publication (SP) 800-90C, Recommendation for Random Bit Generator (RBG) Constructions. This Recommendation specifies constructions for the implementation of 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 in SP 800-90A, and entropy sources, as specified in SP 800-90B. 

On May 2-3, 2016, NIST will host a workshop on Random Number Generation to discuss the SP 800-90 series of documents--specifically, SP 800-90B and SP 800-90C. 

Please send comments to rbg_comments@nist.gov (Subject: "Comments on Draft SP 800-90C"), preferably using the comment template provided.
Comments period ended Monday, June 13, 2016 at 5:00PM EDT.
