Hello CoRE,

We have recently submitted a new version of the draft "Combining EDHOC and OSCORE".

https://tools.ietf.org/html/draft-palombini-core-oscore-edhoc-02

This document defines an optimization for combining EDHOC (run over CoAP) with the first subsequent OSCORE transaction. This reduces the number of round trips required to set up an OSCORE Security Context and to complete an OSCORE transaction using that Security Context.

This update covers especially:

1) Having only one signaling method, using the new EDHOC option, based on feedback from IETF 109 and implementors. This includes a reasoned proposal for the option number.

2) Improved presentation of the message processing, with an additional optimization to save more bytes on the wire. The provided example has also been updated.

3) Improved success and error handling on the server side.

Any feedback, questions or comments are welcome.

Best wishes
Rikard Höglund

Abstract:
   This document defines an optimization approach for combining the
   lightweight authenticated key exchange protocol EDHOC run over CoAP
   with the first subsequent OSCORE transaction.  This combination
   reduces the number of round trips required to set up an OSCORE
   Security Context and to complete an OSCORE transaction using that
   Security Context.

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.
