[stir] Re: Verifiable Voice Protocol (VVP)

[Orie <[e-mail]>]

Hi Daniel ! & STIR,

First time seeing this draft : )

There have been some STIR presentations of applicability of the "Issuer,
Holder / Presenter, Verifier" model for verifiable credentials to STIR WG,
at previous IETFs.
For folks less familiar with Verifiable Credentials, they are sorta like
https://datatracker.ietf.org/doc/html/rfc5755
They are also worked on in OAUTH and SPICE, with primitives coming from
JOSE / COSE (or other security mechanisms like
https://www.w3.org/TR/vc-data-integrity/, or
https://trustoverip.github.io/tswg-acdc-specification/ )

Here are some related drafts to consider:

- https://datatracker.ietf.org/doc/draft-ietf-oauth-sd-jwt-vc/
- https://datatracker.ietf.org/doc/draft-wendt-stir-vesper/

The security technology "ACDCs" have also been proposed in this draft:

- https://datatracker.ietf.org/doc/draft-smith-satp-vlei-binding/

I'll leave it to the STIR chairs to handle the agenda discussions, just
thought I would share some background on this topic.

Regards,

OS, ART AD
