# Security Architectures Issues: Zero-Trust Trust Domains, Roots-of-trust models: EUID ARF 1.4 and KERI

A 38-slide deck by Samuel M. Smith comparing roots-of-trust models in the EU digital identity ARF (Architecture and Reference Framework) 1.4 and KERI (Key Event Receipt Infrastructure). It covers the secure attribution problem, administrative, algorithmic and autonomic trust bases, the LEI and vLEI, flaws of DNS/CA PKI, zero-trust architectures and pre-rotation.

Labels: reading level Practitioner; evidence informative (an author's paper, deck, tutorial or post explaining the suite).
