AES Info and Update... The NIST Advanced Encryption Standard (AES) initiative was put in place to find a replacement algorithm for DES which is quickly approaching the end of its useful life. NIST has coined AES as “The Crypto Algorithm for the 21st Century.” The process for selecting the AES algorithm(s) will be largely based on public involvement in addition to NIST evaluation. NIST called for candidate algorithms from the public and received 21 algorithms in response. Six of the received packages were incomplete and thus disqualified, leaving 15 algorithms as contenders. Five of these 15 algorithms were submitted by U.S. companies or cryptographers while the other ten were international. The goals of the AES algorithm have been stated by NIST to be the following:  Symmetric, block cipher with variable key size (128, 192, 256), and large (128-bit) block size.  More secure and efficient than TripleDES.  Royalty-free worldwide.  Security >30 years.  Public confidence in AES algorithm, based on involvement in submission and analysis efforts. The algorithms will be judged based on the following:  Security  Cost (royalty-free, computational efficiency, memory requirements)  Algorithm and Implementation Characteristics ( Flexibility e.g. additional block sizes, variety of platforms, stream cipher, MAC generator, pseudo-random number generator, hashing algorithm, etc…; Hardware and Software Suitability; Simplicity) Timeline of Activities 09/12/1998 NIST issues a call for algorithms for AES 08/20/1998 NIST announces the 15 candidate algorithms at the First AES Candidate Conference and opens the Round 1 Comment Period 03/22/1999 Second AES Candidate Conference held.
