Hi,

As I mentioned during our meeting today, a few of us interested in remote attestation mechanisms and protocols will have a side meeting on Thursday after the IETF sessions. Here you go the space-time coordinates and some initial reflections to lure you into it:

At *7:15pm EDT (CT)*,
On *Thursday, July 19th*,
In room *Square Dorchester*,
which is here: https://datatracker.ietf.org/meeting/102/floor-plan#2nd-floor-convention-floor-2

Although it is a Bar BoF (great), it is now on-site (not so great), but
we will have a projector with HDMI (curious little detail, but interop
guys will know...), to enable remote call-in (thx Ned for supporting that).

We are planning to find (or create) an appropriate place for
remote attestation related work in the IETF with a Bar BoF as a first step.

Some context:

In essence, remote attestation procedures are a tool-set that is
intended to increase the confidence that an entity other entities
interact with is a trusted system.

Remote attestation typically is tied to a type of trust anchor or
shielded secret, which is - in a sense - a tad bit exotic in the scope
of protocols developed in the IETF as those exist and operate "inside
the box". In contrast, most IETF solutions operate "between boxes".
While remote attestation procedures require both parts in order to
provide a value, appropriate network protocols to convey corresponding
information between boxes are still very much work in progress.

The Plan:

To create appropriate protocols and architectures, unfortunately, is not
a trivial task. In order to find out how this "non-trivial" thing can be
talked about and how to do that constructively in the IETF, we would
like to invite you to a Bar BoF.

The minimum goal is to talk about what remote attestation means
(semantic), what parts of it would belong in the IETF (scope), how to
align existing work and how to provide a basis for future work
(solution). Even better, if we would be able to agree in some of these
areas and flock together.

Some references of the work in this space that is scattered all over the
IETF:

There also is the [email-masked]<mailto:[email-masked]> list (as you can see in the email
header) and a place at github (https://github.com/ietf-rats).

All that said, we would welcome you to drop by and are looking forward
to a lively discussion.

Be goode,
