I oppose the adoption of the EDHOC.

The whole point of a standards setting organisation is to ensure that things work together when different people make them. Interoperability is the most important result of setting a standard. But when we start standardising multiple solutions to the same problem, we introduce new incompatibilities, which goes against the very reason for our existence. If we standardise more than one solution to a problem, there needs to be a really good reason. If not, why even bother standardising anything in the first place?

In my opinion, there are only two instances where we as the IETF should pursue two standards that fulfil the same role:
1. When they cater to substantially different use cases.
2. When there is a measurable and substantial improvement in performance.

Where EDHOC is concerned, I believe that the use cases are identical to those of DTLS.
I do not believe that there is a measurable performance improvement between applications that adopt either of these approaches, particularly when cTLS is included in DTLS.

This being the case, I believe the IETF should concentrate on cTLS and ensure that it meets all the necessary use case coverage, performance, and security requirements, rather than increasing the fractures in the IoT space and causing more headaches for implementers.

Best Regards,
Brendan

Subject: [Lake] Call for adoption for draft-selander-lake-edhoc - respond by June 22

Hi all,

Since we now have a rough consensus on the requirements document, we are proceeding with the selection of the LAKE for OSCORE our working group is chartered to work on. Given:

- the LAKE working group charter,
- a wide community support over an extensive period of time for draft-selander-lake-edhoc,
- adoption of the cTLS draft by the TLS working group where it will be further developed,
- that no other drafts have been submitted for consideration of the LAKE working group,

we are now launching a call for adoption for https://tools.ietf.org/html/draft-selander-lake-edhoc-01.

Please reply to this thread whether you support the adoption, and indicate if you are ready to review if this draft becomes a working group document.

The call for adoption ends on June 22nd, 2020.

Your LAKE chairs.
