# Aes meaning

Advanced encryption standard.

abbreviation

(

**A**dvanced**E**ncryption**S**tandard) 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.A symmetric key encryption algorithm that supports key lengths of 128, 192, and 256 bits. AES superseded Triple DES (Data Encryption Standard), which has a 128-key length and is considered too slow and processor-intensive. Developed by the National Institute of Standards and Technology (NIST), AES has been adopted by the United States government for use with sensitive unclassified documents.
