   The ARIA Algorithm and Its Use with the Secure Real-time Transport
                             Protocol(SRTP)

Abstract

   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.
