The NIST Special Publication (SP) 800-90 series of documents supports the generation of high-quality random bits for cryptographic and non-cryptographic use. SP 800-90A specifies several deterministic random bit generator (DRBG) mechanisms based on cryptographic algorithms. SP 800-90B provides guidance for the development and validation of entropy sources. This document (SP 800-90C) specifies constructions for the implementation of random bit generators (RBGs) that include DRBG mechanisms as specified in SP 800-90A and that use entropy sources as specified in SP 800-90B. Constructions for three classes of RBGs (namely, RBG1, RBG2, and RBG3) are specified in this document.
