    abstract =  {The existing DTLS-SRTP specification allows SRTP keys to be established between a pair of SRTP endpoints. However, when there are more than two participants in an SRTP session, DTLS-SRTP is unable to provide a single key for all of the participants. This existing limitation of DTLS-SRTP prevents deploying DTLS-SRTP in certain scenarios. This document describes an extension to DTLS-SRTP called Key Transport (KTR). This extension transports SRTP keying material from one DTLS-SRTP peer to another, so the same SRTP keying material can be used by multiple DTLS-SRTP peers. This extension eliminates the need to key each SRTP session individually, allowing cost-effective deployment of several DTLS-SRTP scenarios.},
