Minutes review

<McCool> https://www.w3.org/2021/11/15-wot-sec-minutes.html

McCool: I looked into several IETF documents.
… having some thoughts how to proceed with it.

McCool: Anyone having objections?

no objections.

Local transport and secure onboarding

https://github.com/w3c/wot-security-best-practices/pull/28

McCool: I read the IETF specification and added a PR for the security-best-practices accordingly.

McCool: Problem is that TLS 1.3 has been released, but DTLS 1.3 hasn't been released yet.

Jiye: For TLS1.3 this privacy expose risk is not happening?

McCool: I don't know if that is a problem in TLS1.3.

McCool: Offline and local networks are different. Local networks only have a NAT, while offline networks don't have a connection to the Internet at all. We should split that up in different sections.

Jiye: I wanted to talk about the onboarding stuff.

mm added a comment to PR #28

https://github.com/w3c/wot-security-best-practices/pull/28#issuecomment-975534690

McCool: I think the terminology is confusing.

Jiye: I agree. What is the onboarding, config, certificates? We should clarify the context.

McCool: The context should be WoT. We can assume that the certificates situation is solved.

Jiye: In order to setup the device we may want to use a mobile phone.

McCool: We have a lifecycle section in the architecture section. It is a bit contradicting and too short anyways.

McCool: We have the problem that the term "onboarding" is used for a lot of things in the industry.

McCool: There is also a discussion about group keys.

McCool: In general groups keys are problematic and have holes in them. They are also difficult to update.

McCool adds a comment to #28

https://github.com/w3c/wot-security-best-practices/pull/28#issuecomment-975547662

McCool: I need to re-read the specification. I am going to add all the references when I find them to the comments.

ACTION: Separate local and offline sections.

ACTION: deal with TLS1.3 and DTLS1.3

ACTION: finish reading DID, VC, SZTP, BRSKI, Authz, EST
