Subject Identifiers for Security Event Tokens
draft-ietf-secevent-subject-identifiers-06
Abstract
Security events communicated within Security Event Tokens may support
a variety of identifiers to identify the subject and/or other
principals related to the event. This specification formalizes the
notion of subject identifiers as named sets of well-defined claims
describing the subject, a mechanism for representing subject
identifiers within a JSON object such as a JSON Web Token (JWT) or
Security Event Token (SET), and a registry for defining and
allocating names for these claim sets.
