Selection of the Advanced Encryption Standard

Our project investigates the selection of the Advanced Encryption Standard (AES) that was concluded in October, 2000. We sought to explore the criteria used to select the cipher, and how these criteria were ultimately weighted. Research and investigation revealed that the decision was made with two main criteria for selection, security and efficiency. The first conclusion noted was that the measurement of the security and efficiency variables is very difficult. Secondly, a tradeoff between the two criteria constituted a conscious policy decision made by NIST. Ultimately, the NIST selection of Rijndael as the winner reflects a "security to a point" policy in which some security concessions could be made to increase efficiency.
