1. Introduction
OAuth 2.0 Token Introspection [RFC7662] specifies a method for a
protected resource to query an OAuth 2.0 authorization server to
determine the state of an access token and obtain data associated
with the access token. This enables deployments to implement opaque
access tokens in an interoperable way.
The introspection response, as specified in OAuth 2.0 Token
Introspection [RFC7662], is a plain JSON object. However, there are
use cases where the resource server requires stronger assurance that
the authorization server issued the token introspection response for
an access token, including cases where the authorization server
assumes liability for the content of the token introspection
response. An example is a resource server using verified person data
to create certificates, which in turn are used to create qualified
