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.
-
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.
-
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
-

- 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.
