This key SHALL be generated on the PIV Card. The PIV Card SHALL NOT permit exportation of the PIV authentication key. The cryptographic operations that use the PIV authentication key SHALL be available through the contact interface and MAY additionally be available over the virtual contact interface of the PIV Card. Operations that use the PIV authentication key SHALL NOT be available through the contactless interface of the PIV Card. Private key operations MAY be performed using an activated PIV Card without explicit user action (e.g., the PIN need not be supplied for each operation).

The PIV Card SHALL store a corresponding X.509 certificate to support validation of the public key. The X.509 certificate SHALL include the FASC-N in the Subject Alternative Name (SAN) extension using the pivFASC-N attribute to support physical access procedures. The X.509 certificate SHALL also include the card UUID value from the GUID data element of the CHUID in the SAN extension. The card UUID SHALL be encoded as a Uniform Resource Name (URN), as specified in Section 3 of [RFC 4122]. The expiration date of the certificate SHALL be no later than the expiration date of the PIV Card. The PIV authentication certificate MAY include a PIV background investigation indicator (previously known as the NACI indicator) extension (see Appendix B.2). This non-critical extension indicates the status of the cardholder’s background investigation at the time of card issuance. Section 5 of this document specifies the certificate format and the key management infrastructure for the PIV authentication key.
