Hi Hannes,

To your question:

I am wondering why the two documents <draft-ietf-rats-corim> and <draft-ietf-rats-concise-ta-stores> aren’t merged.

The work on Cots started at different point in time (by different authors) and hence the CoRIM base document does refer Cots but is not fully integrated.

We will discuss the possibility and implications of such in our regular CoRIM meetings.

Regarding Trust Anchors as per RATS document (RFC 9334) to the best of my knowledge it comes under the heading of Endorsements.
https://datatracker.ietf.org/doc/html/rfc9334#name-endorsements

RATS treats Trust Anchors as a type of Endorsements.

Hope this information is helpful.

Regards,
Yogesh

Hi Hannes,
On 13.12.23 21:24, hannes.tschofenig=40gmx.net@dmarc.ietf.org<mailto:hannes.tschofenig=40gmx.net@dmarc.ietf.org> wrote:
I am wondering why the two documents <draft-ietf-rats-corim> and <draft-ietf-rats-concise-ta-stores> aren’t merged. Reading through the RATS drafts I often get the impression that trust anchors have somehow been forgotten and were added later, as an afterthought. The RATS architecture RFC does not list trust anchors as an item in Figure 1. In some other document trust anchors are then portrait as belonging to reference values – somehow. That does not feel right to me either.

I think it is completely wrong to consider trust anchors as Reference Values. Can you name the document which presents this view?

Ciao
Hannes

Cheers,

Usama
