Providing encrypted real time data transmissions on a network

摘要

A method and system for providing secure network communications that are provided in a communications protocol designed to support real time (or nearly so) communications on networks such as the Internet. Encrypt/decryption parameters and techniques are determined by the network endpoints whose communications are to be encrypted. Such determinations are made in a control protocol that controls network communications in the communications protocol. The communications protocol may be the Real Time Protocol (RTP), and the control protocol may be the Real Time Control Protocol (RTCP).
