NIST Special Publication 800-63B-4: Authentication and Lifecycle Management
Description: These guidelines focus on the authentication of subjects interacting with government systems over open networks, establishing that a given claimant is a subscriber who has been previously authenticated. The result of the authentication process may be used locally by the system performing the authentication or may be asserted elsewhere in a federated identity system. This document defines technical requirements for each of the three Authentication Assurance Levels (AALs).
