Re: [6tisch-security] people who have responded -- planned meetings

Apologies for the late response, as I am in Califorina, 1pm Paris would be 4am my time which I don't think I can make.
I did do a very late response to the doodle....

All,
The most popular date for meeting is Thursday 1pm Paris time. Let's meet then.

I had already proposed to have the meeting 45 minutes before the 6tisch call,
but to do it weekly.

It would not work for me on a sufficient number of Thursdays that it would be
a problem.

I'm fortunate that I've read most of these documents in detail.
I agree that this is an important thing to consider.

I want to point out that OSCOAP does not have a clear session key exchange
protocol as yet (several ideas proposed), and once it does, it still needs to
do enough certificate processing and ownership voucher analysis to enable the
security.

I had proposed DTLS/COAP (are we calling this coaps yet.. rhymes with soaps?)
with blockwise support.  From my point of view, sitting inside the
unconstrained JCE, it matters little if it's OSCOAP (security inside COAP) vs
DTLS/COAP (security outside of COAP).  They seem to have the same essential
properties in the end.

**to the constrained node it matters that we reuse as much code as possible**
