RIN 0693-ZA-42
Announcing Draft Federal Information Processing Standard (FIPS)
for the Advanced Encryption Standard (AES) and Request for Comments
AGENCY: National Institute of Standards and Technology (NIST),
Commerce.
ACTION: Notice; request for comments.
-----------------------------------------------------------------------
SUMMARY: Recently, NIST announced its selection for the Advanced
Encryption Standard (AES) in a report available at http://www.nist.gov/
aes/, and this selection for the AES has now been described in detail
in a Draft Federal Information Processing Standard (FIPS) for the AES.
The Draft FIPS for the AES specifies technology that can be used to
protect the confidentiality of sensitive (unclassified) electronic
information. The AES specification will provide a FIPS-approved
encryption algorithm in addition to the Triple Data Encryption
[[Page 12763]]
Algorithm (``Triple DES''), which is specified in FIPS 46-3.
NIST invites public comments on the Draft FIPS for the AES. After
the comment period closes, NIST will analyze the comments, make changes
to the document, as appropriate, and then propose the draft standard to
the Secretary of Commerce for approval as a FIPS.
DATES: Comments on the Draft FIPS for the AES must be received on or
before May 29, 2001.
Specifications: Specifications for the Draft FIPS for the AES are
available through the AES home page: http://www.nist.gov/aes/.

SUPPLEMENTARY INFORMATION: In January 1997, NIST initiated an effort to
develop the Advanced Encryption Standard (AES), which would provide
cryptographic security well into the twenty-first century. In August
1999, NIST announced five publicly submitted candidate algorithms as
finalists for the AES, and invited public review, comment, and analysis
in order to make a selection for the Draft FIPS for the AES. During the
Round 2 technical evaluation period, these five finalists were
subjected to extensive analysis and testing by the cryptographic
community. After much careful study and consideration of the finalists
and Round 2 public comments, NIST made its selection for the Draft FIPS
for the AES, and issued a report explaining that selection. The report
is available at http://www.nist.gov/aes/.
NIST strongly encourages the public to continue performing analyses
of the security of the AES, and to submit those analyses as official
comments in response to this request. Such analyses and other comments
received will be considered by NIST in preparing the final version of
the FIPS for the AES.
NIST seeks detailed comments regarding any intellectual property
that may be infringed by the practice of the algorithm(s) in the Draft
FIPS for the AES. This includes comments from all parties regarding
specific claims that the practice of a finalists algorithm infringes on
their patent(s). Claims regarding infringement of copyrighted software
are also particularly solicited. NIST views this input as a critical
factor in the eventual widespread adoption and implementation of the
Draft FIPS for the AES.
NIST reminds all interested parties that the AES development effort
is being conducted as an open standards-setting activity. Specifically,
NIST has requested that all interested parties identify to NIST any
patents or inventions that may be required for the use of AES. Public
comments received in response to this request will be posted
periodically during the comment period at http://csrc.nist.gov/
cryptval/aes/draftfips/.
To encourage on-going discussions related to the AES, NIST will
continue to maintain its AES electronic discussion forum at http://
aes.nist.gov/aes/. Please note that comments posted at that site will
NOT be considered ``official'' comments.
No additional conferences are planned for the Draft FIPS for the
AES at this time.
NIST intends to develop a Draft FIPS for AES Modes of Operation.
Given the need for further public discussion and study of suggested
modes of operation, NIST will hold a public workshop to discuss the
Draft FIPS. Details on this effort are located at http://www.nist.gov/
modes/.
Authority: Federal Information Processing Standards Publications
(FIPS PUBS) are issued by the National Institute of Standards and
Technology after approval by the Secretary of Commerce pursuant to
section 5131 of the Information Technology Management Reform Act of
1996 and the Computer Security Act of 1987, Public Law 100-235.
E.O. 12866: This notice has been determined to be significant
for purposes of E.O. 12866.
Dated: February 20, 2001.

Acting Director, NIST.
