"Authentication"

Used in the Baseline Functional Requirements v1.0

"Authentication" is defined in the IDEF Functional Model in part as a "Process of determining the validity of one or more credentials used to claim a digital identity."

The Functional Model, published as a PDF here: download link, generally sorts core identity management operations into five categories of activities and services, including identity authentication: a full description of this activity type can be found in that document. Among other things, the Functional Model sets forth the following table of functions included within "authentication" in its Functional Elements Descriptions Matrix:

Authentication Request	Process by which authentication is initiated by an entity.
Credential Presentation	Process by which an entity submits a credential for the purposes of authentication.
Credential Validation	Process of establishing the validity of the presented credential.
Authentication Decision	Decision to accept or not accept the results of the credential validation process.
