SRTP means “Secure Real-Time Transport” and it’s a secure cryptographic protocol intended to provide encryption, message authentication and integrity.
SRTP was developed by a team of IP protocol and cryptographic experts from Cisco and Ericsson including David Oran, David McGrew, Marc Baugher, Mats Naslund, Elisabetta Carrara, Karl Norman and Rolf Blom.
SRTP was first published by the IETF in March 2004 as RFC 3711.
Many VoIP hardware and software manufacturers opt for SRTP in order to guarantee secrecy and privacy during a VoIP phone call. SRTP and TLS lay the foundations for a security infrastructure known to be the most efficient “on the market”.
