Hi all,

On 9 Jul 2019, at 09:46, Hannes Tschofenig <hannes.tschofenig@arm.com<mailto:hannes.tschofenig@arm.com>> wrote:
We put together a draft about what I would call version 2 of the OTrP protocol. Why version 2?

As you know, there is some work in Global Platform standardizing the version we have been working on so far in the group.
However, based on the design decisions made so far we are breaking backwards compatibility. We need to distinguish the two versions somehow.

Given the loss of backward compatibility with OTrP v1, I wonder whether it makes sense to change the name. I don’t believe it serves anyone well to have two rather different standards (hence non-interoperable based on them) under the OTrP name.

Given that IETF is trying to achieve something quite different than GlobalPlatform with Teep (and very successfully, to judge by progress so far), I believe there would be benefit in differentiating the Tee work product from existing standards.

Best regards
Jeremy
