Security Event Token (SET)
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.
