1.  Introduction

   This document defines the SDP Security Descriptions attributes
   [RFC4568] corresponding to the ARIA transforms which are defined in
   [I-D.ietf-avtcore-aria-srtp].

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].

1.2.  SRTP Crypto Suites

   The transforms based on ARIA and the corresponding SRTP protection
   profiles for DTLS-SRTP are defined in [I-D.ietf-avtcore-aria-srtp].
   The SDP Security Descriptions [RFC4568] crypto suites corresponding
   to ARIA transforms [I-D.ietf-avtcore-aria-srtp] are sets as shown in
   Table 1.
