Re: [Ace] Chairs

[Kepeng Li]

Hello all,

I would like to take this opportunity to thank all the participants in ACE
WG to support our work.

I enjoyed very much with our ACE work, and I learned a lot from the group.

I will try my best to assist with a smooth transition with Jim Schaad and
Ben Kaduk.

I will continue to participate in the mailing list.

Thank you all!

Kind Regards
Kepeng

[Ace] Call for adoption of draft-seitz-ace-oscoap-profile

[Kepeng Li]

Hello all,
 
According to our virtual interim meeting minutes[1], we have clear supports
to adopt the OSCOAP profile draft [2] during the meeting.
 
This note is asking for confirmation of this tentative adoption decision on
the mailing list.  Please speak up before 7th Nov, 2017 if you would like to
register your opinion on the adoption question.

Keep in mind that adoption of a document does not mean the document as-is is
ready for publication. It is merely acceptance of the document as a starting
point for what will be the final product of the ACE working group. The
working group is free to make changes to the document according to the
normal consensus process.
 
Please reply on this thread with expressions of support or opposition,
preferably with comments, regarding accepting this as a work item.
 
Thanks
 
Kind Regards
Kepeng and Hannes (ACE co-chairs)

Ok then probably was a comparibilitty issue? I was on Linux HTML version of
Webex, and Ludwig too -by his comments-. I sent my chat/votes (I could see
them) , and I could also see (If I recall properly... now Im in doubt)
Ludwig's voties too.
In any case the conclusions reflect the consensus anyway.

[Kepeng Li]

Hi everyone,

So far, the chairs have had two requests for presentations at the ACE
meeting of IETF98, which we will be accommodating along with discussion on
the current draft progress.

We’re putting the agenda together now, and we would like to know if anyone
else has a topic that they’d like to present and discuss at the upcoming
face to face.

Please send feedback to Hannes and me before the end of 17th Mar, including
draft name, presenter, how much time, objectives.

Thanks.

This document is only the starting point for the work and the content will
change as the working group works on it.

Group communication security work has been contributed earlier to the group
and has received a lot of attention. For this reason the call for adoption
happens earlier. The call for adoption of other documents, some of them have
only recently been submitted to the group, will happen soon.

主题:  Re: [Ace] Call for adoption for draft-somaraju-ace-multicast-02


I’m in favour of adopting a profile of the ACE framework [1] providing the
functionality outlined in this draft.

It was acknowledged in the latest ACE interim that this draft will be
transformed into an ACE profile, but currently the mapping to ACE is not
very clear:

- Many of the "Requirements on Profiles” (Appendix C of [1]) are not
fulfilled, e.g. how is the "resource server" of the ACE framework mapped? Is
it the KDC?
- Will the proposed ACE-DTLS profile [2] be used or will we have different
methods for authorising DTLS in different profiles?

There has been a lot of discussion of this draft, whereas
"non-controversial” profiles of ACE ([2], [3], [4]) has been disregarded in
the process. If one profile is being adopted without consideration of other
profiles it may lead to duplication of specification, or different
mechanisms being defined doing the same thing.

Chairs: What is the plan for coordinating the functionality in the different
ACE profiles being adopted?

Sorry, let me make a correction on this.

Usually the call for adoption should take two weeks.

It started from 24 Feb, and should end on 10 Mar.

Kindly remind you to provide your feedback before the deadline.

Re: [Ace] Doodle for ACE virtual interim meeting

[Kepeng Li]

Oh, sorry, my mistake.

I made a mistake between you and Mike Jones.

Let’s change our call to Option 1, 9th Feb, Thursday, GMT 14:00 ~ 15:00.

I will send out the WebEx info later.

Kind Regards
Kepeng

 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.
 
 Mike

[Ace] Doodle for ACE virtual interim meeting

[Kepeng Li]

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/

Thanks,

Kind Regards
Kepeng

[Ace] Summary of ACE Group Communication Security Discussion

[Kepeng Li]

Hello all,  
We had a long discussion about group communication security topic since the 
previous F2F meeting.
Hannes and I have tried to make a summary about the discussion as follows:
·   The solution needs to define both, symmetric and an asymmetric group 
key solution. 
·   The security consideration section needs to explain under what 
circumstances what solution is appropriate. 
If this is not accurate, please let us know.
Kind Regards

Kepeng & Hannes
BTW: it is a pity that I can't attend this meeting due to personal reasons, and 
hope you all have a nice meeting in Seoul!

[Ace] Re： Adoption of Low Latency Group Communication Security Work in ACE

[Kepeng Li]

      Clariication: this is a call for charter addtion of low latency group 
communication security work, rather than call for document adoption.
      The current charter does not include this item yet. Hence we need to get 
feedback about whether or not to recharter the group to take on this work.

Communication Security Work inACE
Hi all,

at the ACE meeting today I asked the participants whether they are in
favor of adding low latency group communication security work in the ACE
group.

20 persons were in favor of doing the work.

5 people argued against doing this work.

If you haven't been at the meeting please contribute your thoughts here
on the list. If you believe you do not have enough information please
also speak up.

Ciao
Hannes
