MIKEY-RSA-R: An Additional Mode of Key Distribution in Multimedia Internet KEYing (MIKEY)
D. Ignjatic, Lakshminath Dondeti, Francois Audet, Ping Lin · 2006
The MIKEY specification describes several modes of key distribution to setup secure RTP 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.
