The IESG has approved the following document: - 'Addition of the ARIA Cipher Suites to Transport Layer Security (TLS)' (draft-nsri-tls-aria-01.txt) as an Informational RFC This document has been reviewed in the IETF but is not the product of an IETF Working Group. The IESG contact person is Sean Turner. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-nsri-tls-aria/ Technical Summary This document specifies a set of cipher suites for the Transport Security Layer (TLS) protocol to support the ARIA encryption algorithm as a block cipher. Working Group Summary The draft was circulated to the TLS WG. There was little (if any) discussion on this particular draft. The one point raised, on the list and by the Responsible AD, was the relationship with ARIA and SEED, which are both national algorithms of the Republic of Korea. While SEED is mainly used for for electronic commerce and financial service, ARIA is for government use and public purpose. In particular, ARIA will be used in VoIP for government. The meta issue surrounding TLS cipher suite drafts was whether the drafts should progress on standards or informational track. The Security ADs polled the SAAG list (and presented this question to a SAAG session) on this particular issue. There was rough consensus that these drafts should progress on the informational track. The AD requested that this draft collect all of the modes for ARIA in one place to aid implementers. Also, the AD requested that SHA-1 be dropped from the list of suites. Document Quality There are no existing implementations of the protocol but the specifications will be used in VoIP for governmental use. Thus many vendors will implement this specification. No reviewer gave special mention. There was not a MIB Doctor, Media Type, or other Expert Review (yet). Personnel The document shepherd for this document is Woo-Hwan Kim <whkim5@ensec.re.kr>.

RFC Editor Note Please make the following changes to the Introduction: OLD: This document proposes the addition of new cipher suites to the Transport Layer Security (TLS) [RFC5246] protocol to support the ARIA [RFC5794] encryption algorithm as a block cipher algorithm. The proposed cipher suites include variants using 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 included. NEW: 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 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. Also please expand PRF in Section 3.3: OLD: The PRFs SHALL be as follows: NEW: The pseudorandom functions (PRFs) SHALL be as follows: _______________________________________________ IETF-Announce mailing list IETF-Announce@ietf.org https://www.ietf.org/mailman/listinfo/ietf-announce
