+3.2.4 Attestation

3.2.4 Attestation

The CSP needs to have a reliable basis for evaluating the characteristics of the authenticator, such as the inclusion of a signed attestation. An attestation is information conveyed to the CSP, generally when an authenticator is bound, regarding that connected authenticator or the endpoint involved in an authentication operation. Information conveyed by attestation MAY include but is not limited to:

The provenance (e.g., manufacturer or supplier certification), health, and integrity of the authenticator and endpoint
Security features of the authenticator
Security and performance characteristics of biometric sensors
Sensor modality
Properties of the authentication key

Attestations SHALL be signed using a digital signature that provides at least the minimum security strength specified in the latest revision of [SP800-131A] (i.e., 112 bits as of the date of this publication).

Verifiers in federal enterprise systems2 SHOULD use attestation features to verify the capabilities and sources of authenticators. In other applications, attestation information MAY be used as part of a verifier’s risk-based authentication decisions.
