The NIST 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. 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.
This draft includes constructions for three classes of RBGs:
SP 800-90C includes a note to readers, guidance for accessing and handling the entropy sources in SP 800-90B, specifications for the initialization and use of the three RBG constructions that incorporate the DRBGs from SP 800-90A, and guidance on health testing and implementation validation using NIST's Cryptographic Algorithm Validation Program (CAVP) and the Cryptographic Module Validation Program (CMVP) that is jointly operated by NIST and the Canadian Centre for Cyber Security (CCCS).
NOTE: A call for patent claims is included on page iv of this draft. For additional information, see the Information Technology Laboratory (ITL) Patent Policy – Inclusion of Patents in ITL Publications.
