Definition

ARIA is a South Korean block cipher that was designed in 2003 and standardised as a Korean Standard block cipher algorithm in 2004.

Background

The ARIA block cipher [3] was designed by a team of South Korean researchers in 2003. Just like the Advanced Encryption Standard (AES), from which ARIA borrows certain ideas, it is a substitution-permutation network (SPN) cipher, has a block size of 128 bits, and supports key sizes of 128, 192, and 256 bits. Unlike most other SPN ciphers, however, ARIA is an involution. This means that the encryption and decryption operation are identical, except for reversing the order of the subkeys. This offers an implementation advantage, which is also found in Feistel ciphers. In 2004, ARIA was selected as a Korean standard block cipher algorithm (KS X 1213) by the Korean Ministry of...
