3.1.7.1 Multi-Factor Cryptographic Authenticators

Multi-factor cryptographic authenticators encapsulate one or more authentication keys that SHALL only be accessible through the presentation and verification of an activation factor (i.e., a password or a biometric characteristic). Non-exportable authentication keys, suitable for use at AAL3, SHALL be stored in an isolated execution environment that is protected by hardware or in a separate processor with a controlled interface to the central processing unit of the user endpoint. Exportable authentication keys (usable at AAL2 or below) SHOULD be stored in appropriate storage that is available to the authenticator (e.g., keychain storage). If accessible to the endpoint being authenticated, authentication keys SHALL be strongly protected against unauthorized disclosure by using access controls that limit access to the authentication keys to only those software components that require access.

External (non-embedded) cryptographic authenticators SHALL meet the requirements for connected authenticators in Sec. 3.2.11. Each authentication event SHALL require input and verification of the local activation factor. Authenticator activation secrets SHALL meet the requirements of Sec. 3.2.10. A biometric activation factor SHALL meet the requirements of Sec. 3.2.3, including limits on the number of consecutive authentication failures. The activation secret or biometric sample and any biometric data derived from the biometric sample (e.g., a fingerprint image and feature locations produced by a fingerprint feature extractor) SHALL be erased after an authentication transaction.
