Authentication Using Secure Messaging Key (SM-AUTH)

Control changed

After · FIPS 201-3

The PIV Card MAY include a secure messaging key and corresponding CVC to establish symmetric keys for use with secure messaging. The same key, CVC, and key establishment protocol can also be used for authentication, since the PIV Card is authenticated in the process of establishing secure messaging. Details of the SM-AUTH authentication mechanism are specified in [SP 800-73] and [SP 800-78].

Some of the characteristics of the secure messaging authentication mechanism are as follows:

• resistant to credential forgery,
• does not provide protection against use of a revoked card,
• low resistance to the use of an unaltered card by a non-owner, and
• usable with contact and contactless readers.
