Second AES Candidate Conference (AES2)
Near the end of Round 1 of the AES Development Effort, the Second AES Candidate Conference (AES2) was held on March 22-23, 1999, in Rome, Italy. At AES2, Round 1 technical analysis was presented and discussed, along with views as to which candidates should be selected as finalists for Round 2.
AES2 was followed immediately by the Sixth Fast Software Encryption Workshop (FSE6), at the same location.
The final agenda for AES2 is available.
NIST Presentations
- At AES2, NIST made several presentations. Please understand that the results presented at AES2 may vary (especially regarding the Java timings) from the final results obtained by NIST.
- NIST efficiency testing results for Round 1. In addition, NIST is providing the timing harnesses it used to test the ANSI C implementations on the NIST Reference Platform (w/ Borland compiler). Intel Corp. has a helpful document which NIST used when creating the "timingtest.c" files. (Questions about this should be directed to Larry Bassham.)
- A small fraction of the NIST statistical testing results were also presented at AES2.

- Slides for several of the presentations are available electronically:
- Instruction-level Parallelism in AES Candidates, Craig Clapp
- Performance Comparison of the AES Submissions, Bruce Schneier
- AES JavaTM Technology Comparisons, Alan Folmsbee
- Implementation of Four AES Candidates on Two Smart Cards, François Koeune
- On the Optimality of SAFER+ Diffusion, James Massey
- Twofish: New Results, Doug Whiting
- List of speakers and titles from the Rump Session.
- Miles Smid chaired a panel of algorithm submitters, which generated a lot of discussion on various AES issues. This panel included discussion of Intellectual Property (IP) issues.
- NIST announced preliminary plans for the Third AES Candidate Conference (AES3). Once again, the AES and FSE conferences will be held back-to-back. More details will be made available in the coming months.
- NIST presented future plans for the AES process, including important information for AES submitters about the transition from Round 1 to Round 2.
- NIST received feedback from the AES2 attendees, regarding their thoughts on the candidate algorithms.
Papers
Here is the complete set of papers that were submitted to AES2, with a link to the submitters' home page (if provided). Please keep in mind that due to the short time schedule, NIST did not go through several rounds of submissions (i.e., not all papers will be "polished"). Links are provided to submitters' home pages, in case they have updated versions of their submissions.
