Status update for WG ace at IETF-100

The ACE WG meet on Tuesday.

At the meeting presentations were given on all of the existing working group documents and several related documents.

The CWT draft is currently in last call and is expected to progress to the IESG before the end of the year.  The related CWT Proof-of-possession document is thought to be in reasonable state and should be able to go into WGLC before Prague.

The main OAuth Framework document has undergone some heavy edits.  The current goal is to try and have a hackathon event at London and if that works well to revise the document if necessary and then go into WGLC.

Two profile documents where then presented.  One for DTLS and one for OSCORE.  The OSCORE draft has formally been adopted as a working group document.  Both of these documents use the framework and describe how to establish secure connections between the client and resource server.  Both of these documents need the framework document to progress before they can.

A presentation was given on a group joining document to support group multicast security.  The document needs to be harmonized with the PubSub draft before the chairs would look at making it a working group document.

A presentation was given on the use of EST over CoAP, the chairs and AD have decided that the current charter allows for this work and the intention is to issue a WG last call in the next month.

The final item was a discussion of a group communication document for lighting where only symmetric keys are used for security and only group authentication is supported.  Following a long discussion there were several hums taken where the WG indicated that it would be interested in such a document where all elements in the group have the same privilege level.  The chairs and AD are going to meet to determine the path forward.
