Abstract

ARIA is a general-purpose block cipher algorithm developed by Korean cryptographers in 2003. It is an iterated block cipher with 128-, 192-, and 256-bit keys and encrypts 128-bit blocks in 12, 14, and 16 rounds, depending on the key size. It is secure and suitable for most software and hardware implementations on 32-bit and 8-bit processors. It was established as a Korean standard block cipher algorithm in 2004 [ARIAKS] and has been widely used in Korea, especially for government-to-public services. It was included in PKCS #11 in 2007 [ARIAPKCS].

Abstract

   This document describes the ARIA encryption algorithm.  ARIA is a    128-bit block cipher with 128-, 192-, and 256-bit keys.  The    algorithm consists of a key scheduling part and data randomizing    part.
