Simon Duquennoy 10. Xavi Vilajosana Action Items 1. Pascal to poll Tero for comments addressed in draft minimal 21 Agenda * Administrivia [2min] * Approval agenda * Approval minutes last call * Status of drafts [Pascal] [5min] * Update on security [Michael] [10min] * Update on 6P [Xavi] [10min] * Preparation for IETF 98[Pascal] [QS] * AOB [3min] Minutes * Administrivia [2min] * Approval agenda Agenda is approved. No issues raised. * Approval minutes last call Las call minutes are approved. No issues raised. * Status of drafts [Pascal] [5min] o Action item Pascal to ping Tero and Suresh about minimal status. * Minimal seems ready according to authors. Waiting for AD to come back. * Update on security [Michael] [10min] * meeting every 2 weeks with an extra meeting in Feb. Tuesdays. * call is to coordinate 6tisch minimal security and zero touch security. * Some real progress on that. * Minimal security: Decided to keep the rekeying outside of the document. to keep it simple. * Some updates to oscoap and edhoc that make the draft obsolete. New version will come with updates. Complication in the proxy mechanism. * Considering a 6tisch specific coap option * not discussed yet within security design team. o considering abandoning fully passive mode for a hybrid * larger enrollement process managed centrally. Looking for COMI interfaces to do that. No consensus on that. * EDHOC * minimal rekey document. Moves all the rekeying process from the 2 drafts. In both of these draft we get a key and we need to rekey. This new document explains this process. * PT: K1 is shared. * MR: Any one that has the K2 can decrypt the packet. When we had a K1 that authenticate beacons only this was only doing that. K1 was thought to be as an ethertype. There is nothing that prevents us to use a single key to both things. It could not be well-known. 6tisch minimal security will provide a unique key for the network. It is not clear if we want to provide 2 keys or with one that is private is enough. o rekey draft presented at the IETF. Michael will call for adoption. * another draft created. Deciding what to be inserted in the EB. Idea to use RAs in the EBs. * PT: One of the implication of using RAs is to help identifying the network to leaf nodes. Something else than the dodagid is needed. * We do not have anything in IP that will be permanent, the prefix is very stable and is a good candidate. * IANA considerations in 6550 will enable the allocation of a number there. * Update on 6P [Xavi] [10min] * Not a lot of progress. * Thomas proposed a reordering that still needs to be implemented. * RELOCATE command was added. * clarification of 2-way and 3-way transactions * Not much progress on Thomas proposal * Preparation for IETF 98[Pascal] [QS] * 6P -> thomas, xavi, qin joining remotely. * Action: Xavi and Qin to agree on who presents. * Diego will present a new version of SF0. * Security has 4 drafts, that will be presented. Merge them? or 4 slots? 2 WG document + 2 new drafts. * MR: 4 slots ok. * 2 hours meeting. More time to solve problems and discuss. * slots can be used for discussion. * slides will be 4:3 for this meeting. * scribes: Diego Dujovne, Dominique Barthel. * jabber: Michael Richardson * AOB [3min] * No other B.
