Re: [AVTCORE] Suite B Profile for DTLS-SRTP Internet-Draft

[Magnus Westerlund <[e-mail]>]

Hi,

If I understand this document correctly there are actually three pieces
to it:

- The SuiteB Crypto algorithms for SRTP
- The SuiteB specific DTLS-SRTP procedures
- Registration of DTLS-SRTP protection profiles

Thus in light of this document and also the ARIA SRTP registration I
think we should discuss how to handle SRTP crypto algorithms and their
connection to the keying mechanisms.

SRTP has at least three different IETF define ways to be keyed:
- DTLS-SRTP [RFC5764]
- MIKEY [3830]
- Security Descriptions [RFC 4568]

And to my understanding they are all used somewhere.

>From my perspective as WG chair I wonder if shouldn't require anyone
that creates a new crypto suit for SRTP to also create the suite
profiles / identifiers for all of these three keying mechanisms?

Opinions?


Secondly, as the part that define the SRTP crypto algorithm needs to go
through this WG I would recommend the authors to submit their draft with
a new filename that includes avtcore as the second part in the filename,
for example as: draft-peck-avtcore-suiteb-dtls-srtp-00.txt
