Selecting the Advanced Encryption Standard (AES): Raising the Bar for Cryptography.
Published
Author(s)
William E. Burr
Abstract
This paper describes how the National Institute of Standards and Technology (NIST) selected the Advanced Encryption Standard (AES), a new standard symmetric key encryption algorithm that has been adopted for use by the US Federal Government, for Standards and Technology (NIST). The paper also describes the NIST follow-on efforts to bring other Federal cryptographic standards up to the same level of strength as AES and to update and extend the NIST standard cryptographic modes of operation.
