R: Public consultation on EU digital principles

Correct, Steve.
In general, “shorten” should perhaps be replaced with “simplify”.
Indeed, validating a credential issued by an unknown issuer requires a complex process of gathering information about that issuer (when available), and taking risk-based decisions.
In the “qualified attribute attestation” model you just check that the attester is listed in the EU trust list, liability is clear.
The model has drawbacks as well…
Best,

I assumed that it meant a shorter trust chain from the verifier perspective

For example
- option 1: clinic issues covid cert to subject.  Health authority issues accreditation cert to clinic.  There is some kind of hash link connection from covid vax cert to clinic accreditation cert.  verifier must follow links and verify both
- option 2: clinic does covid jab and requests certificate issuing directly from national authority
(Oracle as issuer pattern).  Verifier just verified the one cert and trusts the national authority

Hi Luca

I am interested to know how the introduction of an attribute attestation service, presumably between the issuer and holder, can shorten the trust chain. One would have thought that it would do the opposite

Kind regards

Hi Manu,
the consultation is an online survey that anyone can fill in. In parallel the EU Commisison is conducting many one-to-one discussions with different stakeholders.
One of the most relevant aspects under discussion is probably related to “attribute attestation service”, which is a trusted third party acting on behalf of the issuer (to shorten the trust chain):

(from https://ec.europa.eu/newsroom/dae/redirection/document/76608)

I would appreciate any views on that.

For those that don't know about it yet, the EU has opened a consultation,
running through Sept 2021, to get input on future EU digital principles. Folks
that have an opinion (I expect many in this group) may want to join and
provide input.
