Announcement of Proposal to Revise Special Publication 800-22 Revision 1a
January 12, 2022

In August 2021, NIST's Cryptographic Publication Review Board initiated a review process for NIST Special Publication (SP) 800-22 Rev. 1a, A Statistical Test Suite for Random and Pseudorandom Number Generators for Cryptographic Applications.

In response to the public comments received, NIST proposes to revise SP 800-22 Rev. 1a to:

1. address technical suggestions (e.g., new research results, considerations for two-level testing, supporting shorter sequences, independence of the tests)​,
2. clarify the use of the statistical randomness tests,
3. improve the software tool,
4. resolve inconsistencies with the SP 800-22 and SP 800-90 series, and
5. improve the editorial quality of the standard.

Public comments on this proposal may be submitted to cryptopubreviewboard@nist.gov by February 14, 2022. Please use “Comments on SP 800-22 Rev. 1a Decision Proposal” in the Subject.

More information about the review process is available at NIST's Crypto Publication Review Project.
