[TLS] Review of draft-guballa-tls-terminology-03

2016-04-26 Thread Eric Rescorla
I recently reviewed draft-guballa-tls-terminology-03. Comments below. OVERALL I'm sympathetic to concerns that TLS terminology may not be as precise as one would like, but IMO this document doesn't make things significantly clearer and in some cases makes it worse. Specifically: - (D)TLS is inten

My 5 cents. For the IoT environment this ciphersuite is not very useful. If you want the best possible performance, lowest RAM utilization and use as little flash as possible then you go for a plain PSK ciphersuite (without DH/ECDHE). If you are already paying the price of the asymmetric crypto

Yes, adopt. We need something approximately like this and I think that it can proceed well ahead of TLS 1.3. (Dave's nit seems reasonable, but adoption lets us fix that in the working group.) On 26 April 2016 at 05:31, Andrei Popov wrote: > I support adoption of this draft. No reason to limit E

Just to make note on-list, I support adoption of the draft. I've already cited it in the current TLS 1.3 draft as a normative reference, and thus consider it required for completion of the new version. One objection to part of the current draft, though, which I think needs changing. It currentl
