Integrity Transform Carrying Roll-Over Counter for the Secure Real- time Transport Protocol
RFC 4771, “Integrity Transform Carrying Roll-Over Counter for the Secure Real- time Transport Protocol”, is a Proposed Standard document published in January 2007 by V. Lehtovirta, M. Naslund, K. Norrman. The canonical text is published by the RFC Editor.
Abstract
This document defines an integrity transform for Secure Real-time Transport Protocol (SRTP; see RFC 3711), which allows the roll-over counter (ROC) to be transmitted in SRTP packets as part of the authentication tag. The need for sending the ROC in SRTP packets arises in situations where the receiver joins an ongoing SRTP session and needs to quickly and robustly synchronize. The mechanism also enhances SRTP operation in cases where there is a risk of losing sender-receiver synchronization. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
