The symmetric card authentication key is deprecated in this version of the Standard. Both the symmetric card authentication key and the associated SYM-CAK authentication mechanism may be removed in a future revision of the Standard.

If used, the symmetric card authentication key MAY be imported onto the card by the issuer or be generated on the card. If present, the symmetric card authentication key SHALL be unique for each PIV Card and SHALL meet the algorithm and key size requirements stated in [SP 800-78]. If present, cryptographic operations using this key MAY be performed without card activation (e.g., the PIN need not be supplied for operations with this key). The cryptographic operations that use the symmetric card authentication key SHALL be available through the contact and contactless interfaces of the PIV Card and SHALL NOT be available through the virtual contact interface of the PIV Card. This Standard does not specify key management protocols or infrastructure requirements.
