MSDES: More SDES Key Agreement for SRTP
Abstract—SRTP has been designed to provide confidentiality, message authentication and replay protection to the RTP traffic. It is very useful for protecting against voice and video stream eavesdropping. However, a good key management protocol is needed to support SRTP. SDES, ZRTP, and DTLS-SRTP have been proposed as keying protocols. Yet, from the literature, all of them have some drawbacks. So, in this paper, we propose a technique to enhance the SDES protocol to be more secure.
