Authentication Protocol

An Authentication Protocol is a security protocol that defines authentication procedures for verifying entity identity through protocol-based authentication exchanges.

• AKA: Identity Verification Protocol, Authentication Standard, Authentication Scheme, Identity Protocol.
• Context:
  • It can typically specify Authentication Protocol Message Formats through authentication protocol data structures.
  • It can typically define Authentication Protocol Exchange Sequences through authentication protocol flow specifications.
  • It can typically establish Authentication Protocol Security Requirements through authentication protocol cryptographic standards.
  • It can typically provide Authentication Protocol Error Handling through authentication protocol failure mechanisms.
  • It can typically ensure Authentication Protocol Interoperability through authentication protocol standard compliance.
  • ...
  • It can often implement Authentication Protocol Mutual Authentication through authentication protocol bidirectional verification.
  • It can often support Authentication Protocol Session Management through authentication protocol state handling.
  • It can often enable Authentication Protocol Delegation through authentication protocol trust chains.
  • It can often provide Authentication Protocol Replay Protection through authentication protocol nonce mechanisms.
  • ...
  • It can range from being a Simple Authentication Protocol to being a Complex Authentication Protocol, depending on its authentication protocol complexity level.
  • It can range from being a Password-Based Authentication Protocol to being a Passwordless Authentication Protocol, depending on its authentication protocol credential type.
  • It can range from being a Centralized Authentication Protocol to being a Distributed Authentication Protocol, depending on its authentication protocol architecture.
  • It can range from being a Proprietary Authentication Protocol to being an Open Standard Authentication Protocol, depending on its authentication protocol governance model.
  • It can range from being a Legacy Authentication Protocol to being a Modern Authentication Protocol, depending on its authentication protocol technology era.
  • ...
  • It can integrate with Authentication Server for authentication protocol implementation.
  • It can connect to Identity Provider System for authentication protocol identity management.
  • It can interface with Security Token Service for authentication protocol token issuance.
  • It can communicate with Directory Service for authentication protocol user lookup.
  • It can synchronize with Audit System for authentication protocol event logging.
  • ...
• Example(s):
  • Password-Based Authentication Protocols, such as:
    • PAP (Password Authentication Protocol) for simple password transmission.
    • CHAP (Challenge-Handshake Authentication Protocol) for challenge-response authentication.
    • Digest Authentication for hashed credential verification.
  • Cryptographic Authentication Protocols, such as:
    • FIDO2 Protocol for passwordless public-key authentication.
    • Kerberos Protocol for ticket-based authentication.
    • TLS Client Certificate Authentication for certificate-based verification.
  • Federation Authentication Protocols, such as:
    • SAML Protocol for XML-based identity assertion.
    • OpenID Connect Protocol for OAuth-based authentication.
    • WS-Federation Protocol for web service authentication.
  • Multi-Factor Authentication Protocols, such as:
    • TOTP (Time-based One-Time Password) for time-synchronized authentication.
    • HOTP (HMAC-based One-Time Password) for counter-based authentication.
    • FIDO U2F Protocol for hardware token authentication.
  • ...
• Counter-Example(s):
  • Authorization Protocol, which handles permission grants rather than identity verification.
  • Encryption Protocol, which provides data confidentiality rather than authentication.
  • Communication Protocol, which enables data exchange rather than identity verification.
  • File Transfer Protocol, which transfers data rather than authenticating users.
