The following are some notes that pertain to NIST's SP 800-90B. These have all been submitted to NIST as comments to SP800-90B, and are thus public.
- For reference, here is NIST's final SP800-90B (a local copy).
- SP800-90B Comments from UL (Version 1.9, dated 20191212).
- Implementation Comments (Version 20191219).
