Abstract

   This specification defines the Security Event Token (SET) data
   structure.  A SET describes statements of fact from the perspective
   of an issuer about a subject.  These statements of fact represent an
   event that occurred directly to or about a security subject, for
   example, a statement about the issuance or revocation of a token on
   behalf of a subject.  This specification is intended to enable
   representing security- and identity-related events.  A SET is a JSON
   Web Token (JWT), which can be optionally signed and/or encrypted.
   SETs can be distributed via protocols such as HTTP.
