High Quality Content by WIKIPEDIA articles! In cryptography, ARIA is a block cipher designed in 2003 by a large group of South Korean researchers. In 2004, the Korean Agency for Technology and Standards selected it as a standard cryptographic technique. The algorithm uses a substitution-permutation network structure based on AES. The interface is the same as AES: 128-bit block size with key size of 128, 192, or 256 bits. The number of rounds is 12, 14, or 16, depending on the key size. ARIA uses two 8x8-bit S-boxes and their inverses in alternate rounds; one of these is the Rijndael S-box. The key schedule processes the key using a 3-round 256-bit Feistel cipher, with the binary expansion of 1/? as a source of "nothing up my sleeve numbers".
