Technical Summary:
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 SRTP encryption transforms specify how
RTP header extensions are to be encrypted.
Working Group Summary:
This document went through two working group last call. As a result of the
first one there were proposals to add some technical changes that were
consented in the second working group last call.
Document Quality:
The document got good reviews from AVTCORE members including SRTP and
security experts.
Personnel:
Roni Even is the Document Shepherd and the Responsible Area Director is
