This document describes the Secure Real Time Protocol (SRTP), a profile of the Real Time Protocol (RTP) which provides privacy, message authentication, and replay protection. SRTP achieves high throughput and low packet expansion by using an additive stream cipher for encryption, a universal hashing based function for message authentication, and an `implicit' index for sequencing based on the RTP sequence number.
