ARIA (cipher)
Template:Short description Template:More footnotes Script error: No such module "Infobox". In cryptography, ARIA is a block cipher[1] designed in 2003 by a large group of South Korean researchers.[2] 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 8×8-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/[[pi|Template:Pi]] as a source of "nothing up my sleeve numbers".
Implementations
The reference source code of ARIA cipher implemented in C, C++, and Java can be downloaded from KISA's cryptography use activation webpage.[3]
