Advanced Encryption Standard (AES)



Morris J. Dworkin


In 2000, NIST announced the selection of the Rijndael block cipher family as the winner of theAdvanced Encryption Standard (AES) competition. Three members of the Rijndael family arespecified in this Standard: AES-128, AES-192, and AES-256. These use cryptographic keys of128, 192, and 256 bits to encrypt and decrypt data in blocks of 128 bits.
