Re: [arch-d] [Model-t] Possible new IAB program on Internet trust model evolution

[Jari Arkko <[e-mail]>]

It occurs to me that Stephen and I made some assumptions that were not made explicit, and this has lead to some of the questions we’ve received. Perhaps it would be useful to be more explicit. In particular, we really want to extend the threat model, not take away anything that already exists, or start to reconsider the hugely important role of comsec. 

Maybe this change would better describe the scope:

OLD:

The model-t program provides an open venue for analysis of the
Internet threat model and has as a goal to produce a potential update
to BCP72 that defines an Internet threat model that better matches
today's reality.

NEW:

The model-t program provides an open venue for analysis of the
Internet threat model and has as a goal to produce a potential update
to BCP72 that defines an Internet threat model that better matches
today's reality. Specifically, the intent is to document why an update is
needed and provide a suggested update that could be considered by the
IETF. A potential BCP72 update would likely extend the set of threats
considered. Reducing the protection offered by current comsec
mechanisms is a non-goal. Similarly, re-consideration of the parts
of BCP72 that are outside the very narrow part on Internet threat
model is not in scope.
