This section describes the activities and interactions involved in interoperable usage and authentication of the PIV Card. The authentication mechanisms represent how a relying party will authenticate the cardholder (regardless of which agency issued the card) in order to provide access to its systems or facilities. These activities and interactions are represented in functional authentication mechanism diagrams. These diagrams are not intended to provide syntactical commands or API function names.

Each of the PIV authentication mechanisms described in this section can be broken into a sequence of one or more validation steps where Card, Credential, and Cardholder validation is performed. In the illustrations, the validation steps are marked as CardV, CredV, and HolderV to signify Card, Credential, and Cardholder validation, respectively.

Depending on the assurance provided by the actual sequence of validation steps in a given PIV authentication mechanism, relying parties can make appropriate decisions for granting access to protected resources based on a risk analysis.
