An operational PIV system can be logically divided into the following three major subsystems:

• PIV Front-End Subsystem —PIV Card, card and biometric readers, and PIN input device. The PIV cardholder interacts with these components to gain physical or logical access to the desired Federal resource.

• PIV Card Issuance and Management Subsystem —the components responsible for identity proofing and registration, card and key issuance and management, and the various repositories and services (e.g., public key infrastructure (PKI) directory, certificate status servers) required as part of the verification infrastructure.

• PIV Relying Subsystem —the physical and logical access control systems, the protected resources, and the authorization data.

The PIV relying subsystem becomes relevant when the PIV Card is used to authenticate a cardholder who is seeking access to a physical or logical resource. Although this Standard does not provide technical specifications for this subsystem, various mechanisms for identification and authentication are defined in Section 6 to provide consistent and secure means for performing the authentication function preceding an access control decision.

Figure 3-1 illustrates a notional model for the operational PIV system, identifying the various system components and the direction of data flow between these components. The boundary shown in the figure is not meant to preclude FIPS 201 requirements on systems outside these boundaries.
