All,

We submitted -02 of EDHOC this week. The main updates are

* new section 1.2 “Use of EDHOC”
* clarification of intended recipient
* clarification of implicit/explicit key agreement properties
* clarification about caching of cipher suite during/after negotiation
* text on the use of a TEE
* test vectors for authentication with static DH
* clarification and bug fix in test vectors for signatures
* new subsection introducing the bstr_identifier type
* removed unnecessary references

We would like to give a short summary at IETF-109.

Abstract:
   This document specifies Ephemeral Diffie-Hellman Over COSE (EDHOC), a
   very compact, and lightweight authenticated Diffie-Hellman key
   exchange with ephemeral keys.  EDHOC provides mutual authentication,
   perfect forward secrecy, and identity protection.  EDHOC is intended
   for usage in constrained scenarios and a main use case is to
   establish an OSCORE security context.  By reusing COSE for
   cryptography, CBOR for encoding, and CoAP for transport, the
   additional code footprint can be kept very low.

Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org.
