This paper is analysis for E0, C'est le cas notamment de l'Advanced Encryption Standard (AES). Cet algorithme de chiffrement par blocs a ete concu par Joan Daemen et Vincent Rijmen et The Advanced Encryption Standard (AES), also known by its original name Rijndael is a "The Twofish Team's Final Comments on AES Selection" (PDF). Requirements for AES. • In the selection process, NIST asked for: – A block cipher. – Key length: 128, 192, or 256 bit. – Block length: 128 bit. On prefere les algorithmes symetriques pour chiffrer des donnees statiques. Essentiellement AES, Blowfish et Twofish. Rapidite des principaux algorithmes
