You seem to forget that OIDF is building standards that are focused to be used world wide, not with the primary focus like it’s done with ETSI and CEN. I already explained on Tom’s Issue on GitHub that from a European perspective the latest changes in spec are fine to be aligned with the requirements from eIDAS and GDPR. We can implement all requirements for Authentication and Authorization. The approach was already challenged multiple times with security and privacy experts across Europe, and they like the approach.</div><div><br></div><div>Also your second argument „the registrar knows this“, is wrong. It’s not enforced by the implementing acts to handle this and it’s up to the member states how to do this. And this is also not the way the European Commission wants to go via forcing QTSPs for everything! Member States that want to use QTSPs can do so, others can avoid it.</div><div><br></div><div>Long story short: I never agreed with Steffen on his claim and I am open to discuss with others about potential gaps in the protocol that we need to fix in the future.</div><div><br></div><div>#rough consensus</div><div><br></div><div>Cheers</div><div><br></div><div><div>P.S. don’t argue like the person on your mentioned slide pls</div></div><div><br></div><div><div>
