6.2.5 Authentication Using the CHUID (Removed) (was: Authentication Using the CHUID)

NIST PIV and digital identity FIPS 201-3 against FIPS 201-2
All changes in this version
modified 6 PIV Cardholder Authentication part of 6.2

Title changed

Before · FIPS 201-2

After · FIPS 201-3

Authentication Using the CHUID (Removed)

Control changed

Before · FIPS 201-2

The PIV Card provides a mandatory data element called the CHUID. As described in Section 4.2.1, the CHUID contains numerous data elements.

The CHUID shall be used for PIV cardholder authentication using the following steps:

• The CHUID is read electronically from the PIV Card.

• The digital signature on the CHUID is checked to ensure the CHUID was signed by a trusted source and is unaltered.

• The expiration date on the CHUID is checked to ensure that the card has not expired.

• A unique identifier within the CHUID is used as input to the authorization check to determine whether the cardholder should be granted access.

Some characteristics of the CHUID-based authentication mechanism are as follows:

• Can be used for rapid authentication for high volume access control.

• Low resistance to use of unaltered card by non-owner of card.

• Does not provide protection against use of a revoked card.

• Applicable with contact and contactless readers.

As the CHUID authentication mechanism provides LITTLE or NO assurance in the identity of the cardholder, use of the CHUID authentication mechanism is deprecated. It is expected that the CHUID authentication mechanism will be removed from this Standard at the next five-year revision.
