1. Introduction
This document specifies cipher suites for the Transport Layer
Security (TLS) [RFC5246] protocol to support the ARIA [RFC5794]
encryption algorithm as a block cipher algorithm. The cipher suites
include variants using the SHA-2 family of cryptographic hash
functions and ARIA Galois counter mode. Elliptic curve cipher suites
and pre-shared key (PSK) cipher suites are also defined.
The cipher suites with SHA-1 are not included in this document. Due
to recent analytic work on SHA-1 [Wang05], the IETF is gradually
moving away from SHA-1 and towards stronger hash algorithms.
1.1. ARIA
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]. The algorithm specification and object
identifiers are described in [RFC5794].
