Re: [6tisch] I-D Action: draft-ietf-6tisch-minimal-security-07.txt

Mališa,

I am happy with the changes that were made to address my original comments.

Here are a couple of nits you may want to address.

jim

1.	In section 2 use the updated reference to RFC 8174
2.	In section 4 – You might want to make it explicit as one of the item that the pledge identifier is provisioned.

Dear WGLC reviewers, working group,

We submitted a new version of minimal security incorporating the resolution of most of the issues raised during WGLC. There are two remaining issues that still need to be resolved, and I hope to publish these in an additional version after the draft submission cutoff period has passed.

I will discuss the resolutions during the Bangkok meeting but please go ahead an take a look, and let me know if you are happy or not with the resolutions.

List of issues with referenced changesets is available at:

Abstract:
   This document describes the minimal framework required for a new
   device, called "pledge", to securely join a 6TiSCH (IPv6 over the
   TSCH mode of IEEE 802.15.4e) network.  The framework requires that
   the pledge and the JRC (join registrar/coordinator, a central
   entity), share a symmetric key.  How this key is provisioned is out
   of scope of this document.  Through a single CoAP (Constrained
   Application Protocol) request-response exchange secured by OSCORE
   (Object Security for Constrained RESTful Environments), the pledge
   requests admission into the network and the JRC configures it with
   link-layer keying material and other parameters.  The JRC may at any
   time update the parameters through another request-response exchange
   secured by OSCORE.  This specification defines the Constrained Join
   Protocol and its CBOR (Concise Binary Object Representation) data
   structures and configures the rest of the 6TiSCH communication stack
   for this join process to occur in a secure manner.  Additional
   security mechanisms may be added on top of this minimal framework.
