* [07:30] draft-ietf-6tisch-minimal-security (Malisa Vucinic)
    * Malisa presents
    * New version published october 30th
    * relies completely on PSK. Removed dependency on EDHOC draft. Not adopted
    yet. * summarizes updates.
        * PSK is used.
        * key derivation process
        * changes in OSCORE cause changes in this draft, in particular new key
        and nonce derivation * other changes are detailed. The pledge must now
        manage its retransmission because the JRC may drop messages silently,
        which duplicates the confirmable process in CoAP, but the latter
        cannnot be used * join request now a POST even if no need for parms as
        of today

        * also untrusted neighbors are stored in a separate cache
        * Michael suggests that maybe there oculd be a Track for joins with  a
        low and fixed bandwidth * Pascal suggests that the SF could be
        sensitive to QoS (TOS bits) in cell allocation. Join could have low TOS
        values and SF could ignore it. * Michael suggests that we mandate
        tagging now even if we are not fully * Thomas suggests to start a ML
        thread on tagging join traffic and see where that goes
* [07:45] draft-chang-6tisch-6top-msf   (Tengfei Chang)
    * Xavi presents on behalf of Tengfei
    * Minimal scheduling function to wrap up the needed steps for distributed
    allocation of cells in a 6TiSCH network. * provides the policy for
    distributed scheduling to complete the 6TiSCH minimal story * provides a
    rule for using the minimal cell between DIOs, EBs, etc... * Xavi presents
    the lifetime steps
* [08:00] Adjourn
