Algoritmo de cifra basado en un secreto compartido (clave). Cifra el texto en bloques de 128 bits. Utiliza claves de 128, 192 o 256 bits.
A U.S.
Government-approved cryptographic algorithm that can be used to protect
electronic data. The AES algorithm is a symmetric block cipher that can encrypt
(encipher) and decrypt (decipher) information. [CNSSI_4009:2010]
(N) A U.S. Government standard [FP197] (the successor to DES) that (a) specifies "the AES algorithm", which is a symmetric block cipher that is based on Rijndael and uses key sizes of 128, 192, or 256 bits to operate on a 128-bit block, and (b) states policy for using that algorithm to protect unclassified, sensitive data. [RFC4949:2007]
a symmetric
encryption mechanism providing variable key length and allowing an efficient
implementation specified as Federal Information Processing Standard.[ISO-18028-4:2005]
A NIST-standard
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 DESs 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.

Algorithme de
chiffrement basé sur la cryptographie symétrique, AES est le remplaçant de DES.
Face aux vulnérabilités du DES vis-à-vis des attaques par force brute,
l'institut NIST a lancé en janvier 1997 un appel d'offre pour le remplacement
du DES par un nouvel algorithme de chiffrement par blocs de 128 bits, supportant
des clés de chiffrement de 128, 192 et 256 bits minimum. Parmi les 5
algorithmes retenus (MARS, RC6, Rijndael, Serpent, Twofish), l'algorithme belge
Rijndael a été choisi.
