The new version contains some editorial changes and corrections, and more descriptions on transport and error handling.

-	Some editorial changes and corrections.
-	More description on transport based on the comments from Valery Smyslov. Transport appendix moved to the main body of the document. Made it clearer already in the introduction that CoAP is the main intended transport.
-	Corrected DLTS numbers (legacy_cookie was missing) and added more info on how the size comparison was done (variable lengths, #offered algorithms, etc.).
-	More description and examples on error handling
-	Some variable changes and updated figures based on a review by Karl Norrman.
-	More rationale and security considerations

Cheers,
John

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.  A main use case
   for EDHOC is to establish an OSCORE security context.  EDHOC uses
   COSE for cryptography, CBOR for encoding, and CoAP for transport.  By
   reusing existing libraries, 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.
