The Secure Real-time Transport Protocol (SRTP) provides
authentication, but not encryption, of the headers of Real-time
Transport Protocol (RTP) packets.  However, RTP header extensions may
carry sensitive information for which participants in multimedia
sessions want confidentiality.  This document provides a mechanism,
extending the mechanisms of SRTP, to selectively encrypt RTP header
extensions in SRTP.

This document updates RFC 3711, the Secure Real-time Transport
Protocol specification, to require that all future SRTP encryption
transforms specify how RTP header extensions are to be encrypted.

This document is a product of the Audio/Video Transport Core Maintenance Working Group of the IETF.

This is now a Proposed Standard.

STANDARDS TRACK: This document specifies an Internet standards track
protocol for the Internet community,and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Internet
Official Protocol Standards (STD 1) for the standardization state and
