§  Plugtest: Have a chat and move ahead with the plugtest. Miguel and MR agreed on going forward with the Plugtest. The weekend before the IETF meeting in Prague. Collocated event between 6TiSCH and CoRe (OsCOAP). - Action: TW to contact Carsten - ETSI: Will organize providing TRT tool - Remark from Michael: Not having NDA in the plugtest. ETSI agreed to not have the NDA. - Maria Rita volunteers to be part of the organization team. - Remy asks for the test descriptions as a markdown document instead of workd or pdf file. - MR should use some online tools. - F-Interop tools will be used.
- The test description will be published by mid of June. - 14th and 15th of July Plugtest. - for each test think how the assertions can be made true or false. - Remy agrees to be proof-reader of the test-description - MR: have a new set of tests that are already done from previous plugtests that can be ported to F-interop. No need to add everything. - Remy: to demo F-Interop in 2 week (next meeting). - Minimal, 6P, Minimal security?
- Malisa: we are at a point were we can use minimal security with pre-shared keys. - MR: agrees. - Remy: are those minimal security frames supported by tshark (wireshark). - Malisa: there is no dissector for OSCOAP in Wireshark. - 6P -> Adapt from previous tests. - Call for experts: send CVs and selection process to write the test description. beta version for mid June. Final version for 1st of July.

§  Adoption of Michael's drafts on security

·        [7: ] Update on security (Michael/Malisa) [10min]

     *   Concern on using EDHOC and OSCOAP which are not being adopted by any WG.
     *   We need a lower network cost mechanism (w.r.t. DTLS) and this 2 mechanisms fit our needs.
     *   the 6TiSCH minimal security needs more explanatory tags indicating why is not covering some aspects. Comment from AD.
     *   Malisa is working to provide an evaluation of the joining overhead considering different mechanisms.
     *   The key of using OSCOAP is the lesser number of packet exchanges.
     *   DTLS has 29 B of overhead.

·        [7: ] Research Liaison Task Force (Thomas) [ 3min]

     *   It might be useful to have some tracking of what is going on in terms of performance, experimentation, evaluation, simulation, etc...
     *   List the ideas of stuff that we would like somebody to work on and validate concepts.
     *   How this was in the RPL days? Pascal.
        *   Nothing formal in RPL.
        *   Might make sense to have somebody looking at what is going on in the research/industry community and link it to our activities.
        *   Use the IETF Wiki, listing the experiments , results, etc....
        *   Xavi volunteers to move this forward.

·        [8: ] AOB?

     *   No other B.
