Hardware Security Key

A Hardware Security Key is a tamper-resistant physical authentication device that stores cryptographic credentials to provide multi-factor authentication through hardware security key cryptographic operations.

• AKA: Security Key, Cryptographic Token, Hardware Authenticator, Physical Security Key.
• Context:
  • It can typically generate Hardware Security Key Signatures using hardware security key private keys.
  • It can typically protect Hardware Security Key Credentials within hardware security key secure elements.
  • It can typically communicate Hardware Security Key Responses via hardware security key interfaces.
  • It can typically require Hardware Security Key User Presence through hardware security key physical touch.
  • It can typically support Hardware Security Key Protocols including hardware security key FIDO2 and hardware security key PIV.
  • ...
  • It can often provide Hardware Security Key Backup Options through hardware security key multiple registration.
  • It can often enable Hardware Security Key Cross-Platform usage across hardware security key operating systems.
  • It can often store Hardware Security Key Certificates for hardware security key PKI applications.
  • It can often implement Hardware Security Key Counters preventing hardware security key replay attacks.
  • ...
  • It can range from being a Basic Hardware Security Key to being a Multi-Protocol Hardware Security Key, depending on its hardware security key feature set.
  • It can range from being a USB-Only Hardware Security Key to being a Multi-Interface Hardware Security Key, depending on its hardware security key connectivity options.
  • ...
  • It can integrate with FIDO2 Authentication Standards for hardware security key passwordless authentication.
  • It can connect to Computer Systems via hardware security key USB ports.
  • It can interface with Mobile Devices through hardware security key NFC communication.
  • It can work with Authentication Management Systems for hardware security key enterprise deployment.
  • ...
• Example(s):
  • Hardware Security Key Models, such as:
    • USB Hardware Security Keys, such as:
      • YubiKey 5 Series Hardware Security Key supporting hardware security key FIDO2, hardware security key OTP, and hardware security key PIV.
      • Google Titan Hardware Security Key providing hardware security key FIDO authentication.
      • Feitian Hardware Security Key offering hardware security key biometric verification.
    • Wireless Hardware Security Keys, such as:
      • YubiKey 5 NFC Hardware Security Key enabling hardware security key contactless authentication.
      • Bluetooth Hardware Security Key supporting hardware security key wireless connectivity.
  • Hardware Security Key Deployments, such as:
    • Enterprise Hardware Security Key Programs, such as:
      • Mandatory Hardware Security Key Policy requiring hardware security key employee authentication.
      • BYOK Hardware Security Key Initiative allowing hardware security key personal devices.
    • Personal Hardware Security Key Setups, such as:
      • Primary Hardware Security Key Configuration for hardware security key daily use.
      • Backup Hardware Security Key Storage ensuring hardware security key redundancy.
  • ...
• Counter-Example(s):
  • Software Authentication Token, which generates software credentials rather than using hardware security key physical protection.
  • SMS Authentication Code, which transmits authentication codes rather than storing hardware security key resident credentials.
  • Biometric Authentication System, which verifies physical characteristics rather than hardware security key possession.
