DICE IETF-89 WG Meeting Summary (for SAAG)

The DICE group had a compact (one hour), well-attended and productive meeting last week. We had two presentations covering our main work items.
        Hannes Tschofenig presented an overview of draft-hartke-dice-profile-03, on which the authors received good feedback on the need to cover peer-to-peer DTLS between constrained devices and some of the decisions that need to be made in the profile draft. We will be calling for WG adoption of this draft today.
        Sandeep Kumar presented the progress on draft-keoh-dice-multicast-security-05, which is related to our multicast DTLS record later WG charter item. Since Vancouver the WG has been debating on the appropriate scope of this work item, and some have argued that source authentication and public-keys are needed. In the meeting there was good agreement that draft-keoh-dice-multicast-security-05 is a reasonable solution for what we were chartered to do, and we should not try to add source authentication to the DTLS record layer. It was agreed to encourage a straw-man draft to be written exploring if an alternative approach would make sense doing this in CoAP including source authentication. This is not in our charter, but the draft is meant to help us determine how to proceed. Sandeep has agreed to work with others on that draft.
        Finally, Ekr mentioned the TLS 1.3 effort and the need for input from DICE regarding DTLS 1.3 and IoT support. We're encouraging the WG to give their feedback regarding DTLS 1.3, and Klaus Hartke is at least interested to write that up as a draft.
