AAL

Authentication Assurance Level (AAL) is an ordinal measurement to measure the strength of an authentication transaction.

Authentication

Verifying a user's identity through methods such as passwords, biometrics, or multi-factor authentication (MFA).

Authorization

Determining what resources a user can access and what actions they can perform.

Biometrics Capture

The collection of biometric data (e.g., fingerprints, facial recognition) to enhance identity verification and card security.

Certificate Authority

A trusted entity that issues digital certificates used to validate the identity of the cardholder.

Cross-Platform (Roaming) Authenticators

Portable (Roaming) devices that support FIDO2/WebAuthn framework for zero trust, passwordless authentication.

Credential Management System

A comprehensive system that manages the issuance and lifecycle management of identities.

Derived FIDO2

A derived FIDO2 credential (DFC) derived from an individual's primary PIV credential.

Derived PIV

A derived PIV credential (DPC or DPIV) derived from an individual's primary PIV credential.

Device Profiles

A set of configurations and settings that define how a specific identity device (such as a smart card, security key, or mobile device) must function.

Digital Signatures

Cryptographic signatures that validate the authenticity and integrity of documents or communications, often tied to the PIV card.

Enrollment Process

Steps taken to collect personal data, biometrics, and digital signatures during the issuance of the PIV card.

FAL

Federation Assertion Level, defined by NIST, evaluates the level of confidence in the identity federation process.

HMAC (Hash-based Message Authentication Code)

A widely used cryptographic technique designed to ensure both the integrity and authenticity of a message.

Lifecycle Management of Identities

The processes and practices used to manage the creation, maintenance, and deactivation of user identities.

IAL

Identity Assurance Level, defined by NIST, conveys the degree of confidence that someone's claimed identity is their real identity.

IAM

A framework that manages digital identities, authenticating users, and authorizing access based on roles and privileges.

Identity Brokering

A mechanism that simplifies authentication by acting as an intermediary between service providers and multiple identity providers (IdPs).

Identity Federation

A process that allows users to use their credentials from one identity provider (IdP) to access resources and services across multiple platforms or organizations.

Identity Provider (IdP)

An entity that creates, maintains, and manages identity information and provides authentication services to relying parties.

Identity Proofing

The process of verifying an individual's identity before issuing a PIV card, often involving document checks and background investigations.

Interoperability

The ability of identities to be recognized and utilized across different federal agencies and systems.

Key Escrow

A security mechanism in certificate management to securely store a copy of a user's private encryption.

Key Management

The secure management of the cryptographic keys issued by a certificate authority.

Mobile Credentials

Digitally stored authentication credentials on mobile devices.

Multi-Factor Authentication

A security mechanism that requires users to provide two or more authentication factors to verify their identity.

OIDC Protocol

An open standard for authentication that is built on top of the OAuth 2.0 framework.

OAuth Protocol

An open standard for authorization that allows third-party applications to securely access a user's resources.

Passkeys

Learn how passkeys (FIDO2) enable passwordless login experience.

Personalization

The process of embedding the cardholder's information, cryptographic keys, and biometrics into the smart card.

PIV Identity

A standard set by the U.S. federal government for identity authentication for all its employees.

PIV Roles

Learn more about the PIV roles as per the NIST FIPS 201 standard.

Platform Authenticators

Device bound or in-built authentication methods that support FIDO2

Public Key Infrastructure (PKI)

The framework supporting digital certificate issuance and management, essential for secure communications and access.

Relying Party

Role-Based Access Control (RBAC) refers to assigning access rights based on user roles within an organization.

RBAC

Role-Based Access Control (RBAC) refers to assigning access rights based on user roles within an organization.

SAML Protocol

An open standard used for exchanging authentication and authorization data between an Identity Provider (IdP) and a Service Provider (SP).

SCIM Protocol

An open standard designed to simplify the management of user identities across different systems and domains.

Security Key and Tokens

Security keys and tokens are physical devices used for two-factor (2FA) or multi-factor authentication (MFA) to enhance online security.

Single Sign-On (SSO)

An authentication process that allows users to access multiple applications or services with a single set of login credentials.

Smart Cards

A physical card containing a built-in memory chip to store and process data electronically for secure transactions and authentication.

User Directory

A centralized database or service that stores and manages information about users and their credentials.

User Federation

A process of connecting and integrating multiple identity systems or directories.

User Provisioning

The process of automating the creation, updating, and deactivation of user identities across multiple systems, applications, and services using SCIM protocol.

Workflows

A defined sequence of tasks, processes, or activities that must be completed to achieve a specific goal.

Zero Trust

A security framework based on the principle of "never trust, always verify."
