Beginning the Process
(January 1997)- Federal Register: Announcing Development of a Federal Information Processing Standard For Advanced Encryption Standard
- Announcement of the Advanced Encryption Standard Workshop - April 15, 1997
- Thirty-three comments on the FR notice were received by NIST.
AES Workshop to Discuss Draft Criteria and Submission Requirements
(April 15, 1997)- April 15, 1997 AES Workshop: Slides presented by NIST regarding the received public comments and NIST's proposed responses, along with an initial proposed draft of the AES development process.
[Slides] [Handouts] - Comments from Bruce Schneier of Counterpane Systems, regarding the AES Workshop (4/15/97) discussion.
Call for AES Candidate Algorithms
(published in the Federal Register, on 12 September 1997)- Call for AES Candidate Algorithms: A request for candidate algorithm nominations for the AES was published in the Federal Register on Friday, September 12, 1997.
- Intellectual Property Agreements:
May 7, 1998 - Clarification of required intellectual property agreements in section 2.D of the call for candidate algorithms.
- Copyright Release Form:
May 6, 1998 - A copyright release form was provided for submitters.
- Submission Checklist:
March 19, 1998 - A draft AES Submission Package Checklist was made available for submitters - a checklist that was used by NIST to review submission packages for completeness.
(Checklist updated 4/21/98 to relfect new Java and C APIs (see tables for sections 2.C.1 and 2.C.2), and to reflect possibility of including KAT and MCT values for other BLOCK sizes, if applicable (see tables for section 2.B.1).
- Export Licensing for AES Analysis:
February 6, 1998 - Information on export licensing for the evaluation and analysis of AES Candidate Algorithm Analysis Packages.
- API Specifications
January 16, 1998 (modified April 15, 1998) - API specifications for ANSI C and JavaTM implementations that were required in submission packages. ANSI C API finalized on 4/15/98.
(April 13, 1998) The NIST-KIT for the Java implementation was made available from Cryptix. (link changed on 9/21/98). This is also available at http://cryptix.moremagic.com/aes/, http://193.192.247.149/mirror/cryptix/aes/, and http://www.bssl.co.uk/mirrors/cryptix/aes/.
Note that for the June 15, 1998 FINAL DEADLINE, submissions were required to conform to the FINAL Java and ANSI C API specifications.
- KAT and MCT Requirements
January 7, 1998 (modified February 17, 1998) - Information regarding the Known Answer Test and Monte Carlo Test values that were submitted with each candidate algorithm was made available.
- AES-related presentations: The following are some presentations about the AES given by NIST personnel.
- AES - A Crypto Algorithm for the Twenty-first Century - given by Miles Smid at the Fifth Fast Software Encryption Workshop (FSE5), March 24, 1998.
