Goran has a good point here.


Actually - I don't think he does.   If there is a sufficiently 
interested group of people that want to talk certificate enrollment and 
there is a chair available and willing then do an interim on that.  If 
there is a group of sufficiently interested group of people that want to 
talk about the roadmap then do an interim on that.  If ACE doesn't want 
to have such an interim then perhaps it still gets done as a virtual 
BOF.  But this has as much legitimacy as any of the other ACE work items.


Virtual interims have another more common name - teleconferences. 
They're cheap to hold.


Don't hold the certificate stuff hostage to the roadmap stuff and don't 
confuse a F2F interim with a virtual interim with respect to providing a 
false either or choice.


The IETF is bottom up - we work on what the members are interested in 
working on.  It's not a great idea holding one idea hostage as a means 
of trying to get work done on something else.

As I mentioned in a previous mail, I’m completely against giving priority
to non-charter items. Therefore the first interim meeting should be
focused on the ACE roadmap - the output from the Wiki activity. If we have
time to discuss certificate enrolment, that is fine. If we want a later
interim for the certificate enrolment discussion that is fine too, as long
as there is sufficient time is given to decide on the ongoing work.

Fair enough.

We either need to make it longer or pick two dates. I prefer the latter.

Hello Kepeng,

The interim should also be to discuss the profiles as that was a
priority from the WG session in Prague.  Goran pulled together the
wiki, now it's up to the WG participants to check the wiki and amend
as needed to allow for a productive session.  Or did you plan on two

Hallo all,

Considering that Mike has strong position about this draft, so I accommodate 
his choice to allow him to participate.
Sorry what?   I'm assuming by "Mike" you mean me. I missed the original doodle 
call and haven't actually made a choice.  I can't actually make the 14th as I'm 
on a plane.

I can make either of the Thursday 9 February times though.

In any event, if the slides are ready ahead of time I'll just provide some 
commentary on the mailing list.   I note that the authors haven't engaged with 
the comments provided by Jim Schaad and it would be useful if they do so.

WRT to the document, its difficult to make any judgements or suggest any 
improvements without understanding the goals of the document.  As a bare 
minimum, up front the document should a) define "low latency" including each 
element that contributes to the calculation  (this has been a moving target - 
it was something like 250ms for DICE and appears to have moved downward in ACE) 
and b) define the security services that are to be provided when using the keys 
served up by this protocol.   (e.g. it currently appears that the document is 
proposing a key management scheme for group confidentiality, group integrity 
and group authentication).   Lastly, the document needs to include any other 
constraints.  In the instant case, low latency may be accomplished by hardware 
for public key operations - but there is a constraint never actually cited in 
the document - low/no cost for the build of the product (it's referred to 
obliquely as processing cost for the constrained device and is more properly 
attributed to the BOM).

If there is any other application besides lighting that has a use for this 
protocol - now is the time to bring it forward.

Finally, a statement of security requirements for the exemplar application 
(lighting) should be provided so that the protocol can be evaluated against 
those requirements to see if we've actually managed to come up with something 
that meets the needs.

Hi all,

To speed up our progress on group communication security draft, we plan to have 
a virtual interim meeting in the middle of Feb.

I proposed four options for the meeting time:
1. 9th Feb, Thursday, GMT 14:00 ~ 15:00.
2. 9th Feb, Thursday, GMT 15:00 ~ 15:59.
3. 14th Feb, Tuesday, GMT 14:00 ~ 15:00.
4. 14th Feb, Tuesday, GMT 15:00 ~ 15:59.

Please indicate your available time from the doodle poll:
http://doodle.com/poll/v6nbeggazekaq2ut

We will mainly discuss this draft:
https://datatracker.ietf.org/doc/draft-somaraju-ace-multicast/
