The Advanced Encryption Standard 论文

摘要

In October 2000, the National Institute of Standards and Technology (NIST) announced that the Rijndael algorithm had been selected to be the new Advanced Encryption Standard (AES). NIST’s announcement concluded a three and a half year search process in which fifteen candidate algorithms from twelve countries were evaluated on the basis of security, computational efficiency, algorithm simplicity, and flexibility. The AES will become a Federal Information Processing Standard (FIPS), thereby replacing the aging and obsolete Data Encryption Standard (DES) as the cryptographic algorithm employed by US Government agencies and the private sector to encrypt sensitive information.
