Advanced Encryption Standard

(cryptography, algorithm)
(AES) The NIST's replacement for the Data Encryption Standard (DES). The Rijndael /rayn-dahl/ symmetric block cipher, designed by Joan Daemen and Vincent Rijmen, was chosen by a NIST contest to be AES.

AES is Federal Information Processing Standard FIPS-197.

AES currently supports 128, 192 and 256-bit keys and encryption blocks, but may be extended in multiples of 32 bits.

(Advanced Encryption Standard) A U.S. government encryption standard supported by the National Institute of Standards & Technology (NIST). AES is a cryptographic cipher that uses a block length of 128 bits and key lengths of 128, 192 or 256 bits. Officially replacing the Triple DES method in 2001, AES uses the Rijndael algorithm developed by Joan Daemen and Vincent Rijmen of Belgium. AES can be encrypted in one pass instead of three, and its key size is greater than Triple DES's 168 bits. In early 1997, the NIST invited cryptographers to submit an advanced algorithm. In late 2000, the Rijndael (pronounced "rine-doll") symmetric block cipher algorithm was selected out of submissions by 21 teams from 11 countries. See cipher, cryptography, NIST, DES and AES/CCMP.
