The IESG has approved the following document: - 'The ARIA Algorithm and Its Use with the Secure Real-time Transport Protocol(SRTP)' (draft-ietf-avtcore-aria-srtp-11.txt) as Informational RFC This document is the product of the Audio/Video Transport Core Maintenance Working Group. The IESG contact persons are Adam Roach, Alexey Melnikov and Ben Campbell. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-avtcore-aria-srtp/ Technical Summary This document defines the use of the ARIA block cipher algorithm within the Secure Real-time Transport Protocol (SRTP). It details two modes of operation (CTR, GCM) and a SRTP Key Derivation Function for ARIA. Additionally, this document defines DTLS-SRTP protection profiles and MIKEY parameter sets for the use with ARIA. ARIA is a Korean standard block cipher algorithm that has been widely used in Korea, especially for government-to-public services. Working Group Summary The primarily thing to note has been the limited interest in this work. However, since the draft registers DTLS-SRTP and MIKEY codepoints for a widely used algorithm, the AVTCORE group adopted the milestone. Document Quality The document has been reviewed by a small group of persons beyond the authors themselves. The document received feedback from Dan Wing and John Mattson from a security perspective. Colin Perkins, Jonathan Lennox, and the shepherd have reviewed it from an RTP perspective. There exist a number of implementations of the ARIA cipher in SRTP. Some are certified by Telecommunications Technology Association of Korea: http://test.tta.or.kr/research/result/index.jsp?team_cd=N&pageNum=2 And looking at specific products like: http://test.tta.or.kr/research/result/network.jsp?team_cd=N&num=987 http://test.tta.or.kr/research/result/network.jsp?team_cd=N&num=971 One can see (using Google translate) that they are listed as supporting ARIA. Shepherd notes that this likely means that the cipher and one form of key-management has been implemented.
