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]. Kim, et al.
