This depends on the evaluation criteria of the verification you conduct with a subject.
We can agree that the initial verifiable evidence that a Trust Anchor/CA has issued a certificate for a subject is the first indication that the subject belongs to a network/framework/shared-regulation/perimeter. Let's consider this mailing list as a trust anchor. We're having a productive conversation under a common trust anchor, where the evidence that connects us is our membership in this community, under the IETF Trust Anchor. However, this alone is not sufficient, because you must read everything I say and empirically evaluate if you can trust me qualitatively. OpenID Federation allows the exchange of metadata to securely establish interoperability and also applies policies that dynamically change this metadata, adding qualitative evidence with trust marks. This is the advancement I found that the X.509 based PKI was not designed for. I use X.509 based PKI for other purposes, since in this universe everything has its right place, and I appreciate this. I also appreciate PIKA in a way to make this grow and get integrated with other models that should not be kept out of the scope of the specification if you agree and if we may have the opportunity to work together in this field Il giorno mer 12 giu 2024 alle ore 12:47 Rohan Mahy <rohan.m...@gmail.com> ha scritto: > Giuseppe, > Given that verifying the issuer is already done using X.509 PKI today, why > do you object to trusting the PKI root for the same purpose (validating the > domain name of the issuer) with the same validity period (between the > notBefore and notAfter of the certificate)? > > Thanks, > -rohan > > On Tue, Jun 11, 2024 at 4:44 AM Giuseppe De Marco <demarco...@gmail.com> > wrote: > >> Ciao Tom, >> >> Public Key Infrastructure satisfies the requirements to provide public >> keys.
