As a part of the periodic review of NIST’s cryptographic standards and guidelines, NIST's Crypto Publication Review Board ("Review Board") announced the review of Federal Information Processing Standards Publication (FIPS) 197, The Advanced Encryption Standard (AES) in May 2021.
NIST proposes to update FIPS 197. An update of a publication is appropriate when it only requires changes to correct errors or clarify its interpretation, and no changes are made to technical content. Proposed changes to FIPS 197 are summarized in the full announcement.
A public comment period for the draft FIPS 197 update is open through February 13, 2023. Public comments on the decision to update the FIPS, or on the draft update itself, may be submitted to firstname.lastname@example.org, with “Comments on Draft FIPS 197 Update” in the subject line. Comments received in response to this request will be posted on the Crypto Publication Review Project site after the due date. Submitters’ names and affiliations (when provided) will be included, while contact information will be removed. See the project site for additional information about the review process.
