No objection provided that the OTrP name and references are dropped. I believe there has been at least some indication on mailing list that this would be acceptable.

I would otherwise object on the basis of published specifications compatible with the original OTrP contribution and based on the SD concept, such as https://globalplatform.org/specs-library/tee-management-framework-open-trust-protocol/ I believe there would be a risk of confusion caused by lack of interoperability between similarly named protocols.

Best regards
Jeremy

CAUTION: This email originated from outside of the organization.
All,

At IETF 105, there was consensus to the question: Is the (TEEP working) group willing to break backwards compatibility with OTrP 1.0?

If there are objections to this decision, please respond by Aug 16th to this email with the rationale for why TEEP should continue OTrP compatibility.

Thanks,
                Nancy
