Subject: [T2TRG] New topic for T2TRG?

Dear T2TRG,

As reported from the CoRE applications side meeting below, there seems to be an interest in progressing topics in the area of security for constrained RESTful environments, and a proposal to host that work in T2TRG.

* What?

CoAP can be used in various settings beyond simple REST. How do we adapt existing security requirements and solutions to these new modes of operation? Some work of this kind is already in progress in the IETF but some issues go beyond the individual IETF WGs, or could benefit from additional contributions from a wider audience, reviews and information sharing.
Examples include:
- Rekeying with PFS vs. stateless operations [2]
- Firmware updates using group communication
- Efficient and secure tunnelling of CoAP in CoAP
- Notifications surviving rekeying
- Progressing pub-sub with CoAP

* Why?

To progress applications of CoAP in different security settings which "touch standardization in the IETF" [1] but are not necessarily in scope of a single working group like CoRE, ACE, SUIT, COSE, LAKE, etc.

* How?

Through a "sister" of WISHI:  A recurring meeting series under the T2TRG umbrella about topics on security for constrained RESTful environments. Working name: seccore (which apparently may mean "dryness" in some Italian context; not intended as a characterization of the content :-)  Frequency and topics open for discussion.

* Comments?

What do people think?

Should we try to have a first meeting before the upcoming holiday season?

the small group was not all that small and very lively -- thanks
everyone for participating!

I've attached the minutes here in case the pad we used[1] goes away.

While we figure out how to best make more of the CoRE ecosystem publicly
visible at coap.technology, we can already start collecting material at
the wiki[2].

Best regards
Christian
