Fixing wot security best practices doc

McCool: we have a number of issues that needs fixing - can see in github issues. I have volunteered for some issues, others need more volunteers

<kaz> wot-security-best-practices Issue 14 - TD Signatures and Object Security

McCool will do an initial cleanup for this issue and then Oliver can continue in July

Issue: Update secure transport section https://github.com/w3c/wot-security-best-practices/issues/13

McCool is explaining the issue based on comments

McCool: if someone volunteers to help with this would be great or be a reviewer

Philipp can probably help with secure transport issue

McCool: if you can try to do a first draft for this

Philipp agrees to try

PR for TD signatures

McCool: we need to have a proper security review for this one

<McCool> https://github.com/w3c/wot-thing-description/pull/1151

McCool: I did a first draft for this

McCool marking in the comments the parts that have been addressed via PR

McCool: I picked enveloped signature type because it is local to this document that it covers, it is also optional.

McCool: need to understand how to do canonicalization and name references

discussing the signature crypto algorithms

Elena was proposing to include stronger cryptography options and making them defaults

Oliver was saying that there is no interest in the 384 versions, it is either 256-based on 512

at the end having a catalog of options and choices should be the best

McCool: does it make a difference to have hash and signature algorithm separately?

Elena: usually they are used together as a pair of similar security strength algorithms

McCool: please review this PR and raise issues

McCool: next meeting lets discuss F2F planning, please take a look and suggest topic
