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

Abstract

   This document describes the use of the ARIA block cipher algorithm
   within the Secure Real-time Transport Protocol (SRTP) for providing
   confidentiality for the Real-time Transport Protocol (RTP) traffic
   and for the control traffic for RTP, the Real-time Transport Control
   Protocol (RTCP).  It details three modes of operation (CTR, CCM, GCM)
   and a SRTP Key Derivation Function for ARIA.
