Re: [AVT] Keying SRTP store and forward
But secure email is done with PGP or S/Mime, which does content
crypto, not transport crypto. So I'm afraid I don't see the analogy.

At my presentation yesterday, keying for e2e protection in
connection with voice mailboxes was discussed. I believe this
discussion got a bit confused as we were coming from differing
starting points and we had different views on what should and/or can
be achieved.
I look at e2e protected mailboxes in a similar way as I consider
secure email. In secure email the sender exactly specifies the
specific person or group of persons he wants to send the email to,
and a receiver can only read his email if his secure email
credentials are available in the terminal he uses. I believe this is
a feature of secure email. If you want to have access to your email
from any terminal (not providing credentials for secure email) you
have to rely on protected transport of the plaintext email from the
email server to the client.
Secure email is a valuable service used many private users and is
also a standard in many large organizations like enterprises,
government authorities etc. I believe that these user groups,
appreciating secure email, should also be offered the possibility to
have e2e protected voice (and multimedia) mailboxes. For this, the
proposed extensions in SRTP are needed.
Note that this work is not only (or perhaps even mainly) motivated
by the voice mailbox use case but also relates to the media
distribution use cases described in the draft.
