The Multimedia Internet Keying (MIKEY) specification describes
several modes of key distribution solution that address multimedia
scenarios (e.g., SIP calls and Real Time Streaming Protocol (RTSP)
sessions) using pre-shared keys, public keys, and optionally a
Diffie-Hellman key exchange.  In the public-key mode, the Initiator
encrypts a random key with the Responder's public key and sends it to
the Responder.  In many communication scenarios, the Initiator may
not know the Responder's public key, or in some cases the Responder's
ID (e.g., call forwarding) in advance.  We propose a new MIKEY mode
that works well in such scenarios.  This mode also enhances the group
key management support in MIKEY; it supports member-initiated group
key download (in contrast to group manager pushing the group keys to
all members).  This document updates RFC 3830 with the RSA-R mode.
