Re: [Lake] Lake charter call for comments

Hi Ben,

Thanks for taking into account my comments, the proposed charter looks good to me.

    Hi all,

    Thanks to everyone for the feedback so far.  In the interest of moving from
    an informal post-BoF discussion to a more structured path forward, this
    message starts a two-week last call for comments and consensus on a LAKE
    charter.  I've tried to incorporate the feedback from Martin and Göran
    (though my editorial hand couldn't resist a few tweaks; all errors are
    mine), and my apologies to anyone whose comments I missed.  Depending on
    how discussion goes, additional revisions may be posted during the comment
    period to help achieve better clarity.  If we get good agreement here, then
    the charter can go to the IESG and IAB for the formal approval process
    (including IETF LC).  Please reply even you have no specific comments; the
    IESG and IAB need to be able to gauge the level of community support for
    and interest in the proposed work.

    Thanks,

    Ben

    Problem

    Constrained environments using OSCORE in network environments such as
    NB-IoT, 6TiSCH, and LoRaWAN need a ‘lightweight’ authenticated key
    exchange (LAKE) that enables forward security.  'Lightweight' refers to:

      * resource consumption, measured by number of round-trips to complete,
        bytes on the wire, wall-clock time to complete, or power consumption
      * the amount of new code required on end systems which already have an
        OSCORE stack

    Goals

    This working group is intended to be a narrowly focused activity
    intended to produce at most one LAKE for OSCORE usage and close.

    The working group will collaborate and coordinate with other IETF WGs
    such as ACE, CORE, 6TISCH, and LPWAN to understand and validate the
    requirements and solution.  draft-selander-ace-cose-ecdhe is a candidate
    starting point for the LAKE produced by the WG.  Any work available from
    the TLS WG that satisfies the determined requirements will also be
    evaluated for suitability.

    Program of Work

    The deliverables of this WG are:

    1. Design requirements of the lightweight authenticated key exchange
    protocol for OSCORE (this draft will not be published as an RFC but will be
    used to drive WG consensus on the deliverable (2)

    2. Specify a lightweight authenticated key exchange protocol suitable for
    use in constrained environments using OSCORE
