   The ARIA Algorithm and Its Use with the Secure Real-time Transport
                             Protocol(SRTP)
                    draft-ietf-avtcore-aria-srtp-07

Abstract

   This document defines 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 RTP Control Protocol (RTCP).
   It details three modes of operation (CTR, CCM, GCM) and a SRTP Key
   Derivation Function for ARIA.
