Minutes

The minutes of the previous 6TiSCH security conference call were approved.

AOB ("Next steps")

  • ThW commented that the revised charter for 6TiSCH would include the join protocol, where rechartering would be discussed at the next face-to-face IETF meeting.
  • RS asked participants on the call re agenda items for the calls prior to the IETF-92 meeting in Dallas (March 2015). He suggested as topics to include (a) time latency aspects of the join protocol; (b) implementation aspects; (c) detailed aspects of the join protocol (packet sizes in bits/bytes). MR suggested the architecture text to be finished, including certificate sizes, flows underlying DTLS, overhead/fragmentation. ThW commented that he had discussed some hardware implementation aspects with RS, where he mentioned (for transparency to the group) that he considered TI's CC2538 System on a Chip (Cortex M3) and the CC2520/ARM Core typical platforms that would fit the 6TiSCH target space.
  • Participants agreed that the next three conf calls would focus on the following topics:
    • time latency aspects;
    • implementation aspects, including hardware;
    • packet sizes, e.g., with DTLS.
