OpenID Federation Trust Chain on Keycloak for Highly Assured Use Cases of Digital Identity Wallet - Yutaka Obuchi, Hitachi
Friday June 13, 2025 16:50 - 17:05 JST
Level 1 | Apollon
OpenID Federation 1.0 provides a framework to build trust between a Relying Party and an OpenID Provider that have no direct relationship so that the Relying Party can send OIDC/OAuth requests to the OpenID Provider without being previously registered.

One primary use case is the trust between an Issuer and a Holder (Wallet) on W3C’s Verifiable Credential Data Model, which is getting a lot of attentions as an approach to realize the Digital Identity Wallet ecosystem.
Especially when high assurance level is needed like EU Digital Identity Wallet, OpenID Federation can provide a strong solution.

In this session:
Firstly I will explain OpenID Federation and the reason why it is important for Digital Identity Wallet ecosystem.
Then I will explain what types of roles Keycloak can play with OpenID Federation Trust Chain.
Also I will show a simple demo of client registration with OpenID Federation Trust Chain on Keycloak.
