Hi Usama,

 

The introduction of https://datatracker.ietf.org/doc/draft-ietf-rats-concise-ta-stores/ gave me the impression that trust anchors are reference values. Please read it too, maybe I am misinterpreting it.

 

Following the response from Yogesh, I believe the text needs to be improved.

 

[CW] While I don’t disagree that the text should be improved, it did not intend to say trust anchors are reference values. I think the problematic sentence is this one: “The extension in this document aims to enable public key material to be decoupled from reference data for several reasons, described below.” The term “reference data” here just meant the CoRIM, which is likely generating the misimpression. The subsequent paragraphs describe why TAs ought move independent of other CoRIM contents, which may inform whether or not to merge the drafts.

 

Ciao

Hannes

Hi Hannes,

On 13.12.23 21:24, 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
