  • [07.27] architecture draft last call

    • the new security text in the architecture draft is not final. It still do not have the consensus from the security team.
    • needs feedback for that part.
    • will be published on Monday.
    • Rene: Changing 2 words on the section solves the issue (referring to suggested disposition of Jonathan Simon's comments on the architecture draft, which according to oral info on phone call, is to the commenter's satisfaction).
    • TW: Can this be resolved in the ML?
    • Rene: commented that there was low activity level on the ML
    • No proposal submitted by everybody on how to improve PSK problems.
    • Discuss of how the overall architecture of the overall joining process should be.
    • According to Rene. There is no technical justification about the comments made to ReneĀ“s proposal.
    • Rene: the text in Section 13 was what was provided by the 6TiSCH Security design team, with unanimous consensus by those who participated on the 6tisch security calls in January. For feedback on comments made on Section 13 of the architecture, please see the detailed technical rationale for disposition (this is not position-based arguing, simply comment disposition based on technical arguments).
    • PT: I was asking to Rene to describe how ISA100 works during a year.
    • TW: the idea of the next IETF meeting is to charter security.
    • Rene: does not support the removal of the section proposed by Rene in the architecture .
      [07.??] minimal draft wrap-up
    • Security in minimal: what to say
    • there will be a network wide network key.
    • The join process is only for autonomic and scalable network bootstrapping.
    • all the nodes have the same key or we have 2 keys? one for the beacon and one for the data.
    • how the keys get there is out of scope.
    • in a network we use 1 key for beacon and another for data
    • key for data and different key for data. data is authenticated.
  • [07.??] AOB

    OTF question about the use of shared cells on reservation. T

    • it seems a confusion with soft cells.
    • move to the ML and at the WG meeting.
    • No 6tisch call next time. INformal calls to synchronize slides.
    • Use case prepared for the track case.
  • [08.13] Meeting ends
