Abstract

   This specification defines the Security Event Token, which may be
   distributed via a protocol such as HTTP.  The Security Event Token
   (SET) specification profiles the JSON Web Token (JWT) and may be
   optionally signed and/or encrypted.  A SET describes a statement of
   fact that may be shared by an event publisher with event subscribers.

1.  Introduction and Overview

   This specification defines an extensible Security Event Token (SET)
   format which may be exchanged using protocols such as HTTP.  The
   specification builds on the JSON Web Token (JWT) format [RFC7519] in
   order to provide a self-contained token that can be optionally signed
   using JSON Web Signature (JWS) [RFC7515] and/or encrypted using JSON
   Web Encryption (JWE) [RFC7516].

   For the purpose of this specification, an event is a statement of
   fact by a publisher (also known as the event issuer) that the state
