Status of the Advanced Encryption Standard (AES) Development Effort
The purpose of this presentation will be to articulate the status of NIST=s Advanced Encryption Standard (AES) development effort. This presentation will include a description of the overall AES development effort, a summary of comments and analysis from the first round of analysis (Round 1), and a discussion of the rationale for NIST's selection of the AES candidate algorithm finalists. Additionally, the author will present some of the analysis activities planned for the second round of evaluation and analysis (Round 2).In January 1997, NIST announced its intention to develop a Federal Information Processing Standard (FIPS) for an Advanced Encryption Standard (AES). The culmination of this multi-year, multi-stage effort will be a FIPS specifying an Advanced Encryption Algorithm (AEA) - an unclassified, symmetric, block-cipher algorithm accommodating multiple key sizes, which is intended to be available royalty-free worldwide. NIST and the public have completed their first round of evaluation of the fifteen candidate algorithms for security, efficiency, and other properties. At the time of NISSC 1999, the finalist algorithms (approximately five) will be undergoing their second round of evaluation and analysis by NIST and the global cryptographic community.
