  FIRST ADVANCED ENCRYPTION STANDARD (AES) CANDIDATE CONFERENCE
Security is, of course, the paramount consideration in the AES selection process and encompasses such issues as the relative security of one candidate as compared to the others, and the extent to which the algorithm output is indistinguishable from a random permutation on the input block.
Each candidate submitter had to sign license agreements provided by NIST identifying any known intellectual property (i.e., patents or patent applications) that may be infringed by the practice of the particular candidate.
In the first AES evaluation round, this will focus primarily upon the 128 bit key size, while in the second round (with about fivecandidates), this will be expanded to include the 192 bit and 256 bit key sizes and hardware performance estimates.

 ADVANCED ENCRYPTION STANDARD (AES) Fact Sheet
It is a comprehensive report that discusses various issues related to the AES, presents analysis and comments received during the public comment period, summarizes characteristics of the five finalist AES algorithms, compares and contrasts the finalists, and presents NIST's selection of Rijndael.
Prior to its evaluation of the five finalists, NIST's AES selection team discussed the issue of whether it should change the number of rounds for one or more of the algorithms, since that issue had been raised by the public during the recent comment period.
For these reasons, NIST's AES selection team decided it would be most appropriate to base its evaluation and selection on the five algorithms as they were originally submitted (i.e., without changing the number of rounds).

 Request for Comments on Candidate Algorithms for the AES
The study was based on the assumption that the AES baseline should depend on the use of commercial-off-the-shelf systems, typically available in most commercial and governmental settings.
The rationale for this type of study is to help characterize the range of expected performance in commercial implementations of the AES candidate codes in typical client/server enterprise settings.
AES Candidate Codes: Because of the limitations of time and the short duration for presentation of results, no optimization for any of the AES candidate codes or code performance reorganization was performed.

Candidates will be judged on security, efficiency, and flexibility, and NIST hopes to have a new standard ready by the end of the century.
For the AES to suit the NSA, there must be an AES candidate that fulfills those requirements.

KAT values are required for operation of the AES candidate algorithms in the Electronic Codebook (ECB) mode only (for all three required key sizes).
Known Answer Test values must be provided with submissions, which demonstrate operation of the AES candidate algorithm in ECB mode, for each of the minimum required key values (128, 192, and 256 bits).
Monte Carlo Test values must be provided with submissions, which demonstrate operation of the AES candidate algorithm in both ECB and CBC modes, for each of the minimum required key values (128, 192, and 256 bits), for both the encrypt and decrypt states.

From this perspective, the lifetime of AES is forever: Although Marvin, with a brain the size of a small planet [14], may aspire to someday search a 128-bit keyspace, no conceivable development in device technology can search 2^256 keys.
It's clear that the AES should not be chosen based on what runs best on 32-bit machines, but based on machines likely to become available in the future.
When the AES criteria were being developed, there was a notion that a tamper-resistant smart card might contain a secret unknown to the owner, and that the AES algorithm should protect this secret.

 Randomness Testing of the AES Candidate Algorithms - Soto (ResearchIndex)   (Site not responding. Last check: 2007-10-29)
Abstract: One of the criteria used to evaluate the AES candidate algorithms was their demonstrated suitability as random number generators.
That is, the evaluation of their output utilizing statistical tests should not provide any means by which to computationally distinguish them from a truly random source.
Coincidentally, the five attacked candidates were also among the slowest candidates.

However, while it seems that the series of byte substitutions, followed by a Pseudo-Hadamard Transform, mixes together the two halves of the block well enough, attacks are possible against this type of construction that make it not much stronger than normal DES, at least in theory.
All the AES candidate algorithms have been disclosed.
It may also be noted that links to the descriptions of the algorithms are available at the Block Cipher Lounge as well as at the official AES site.

 ...And The Winner Of The AES Competition is Rijndael!
The initial call for AES candidate algorithms was published on September 12, 1997.
A similar period of analysis and feedback followed this round two announcement and Rijndael was announced as the AES finalist on October 2, 2000.
Considering that AES desired its final selection to operate on a variety of machines such as personal computers and smart cards, an algorithm would be less desirable if it could only be implemented efficiently given a particular wordsize, for example.
