How does the Feitian Key work?

The Feitian Key uses public key cryptography (PKC) to ensure secure authentication. The process is as follows:

  1. Registration : The user binds the Feitian Key to an account via a supported authentication protocol, such as FIDO2 or U2F .
  2. Challenge and Response : Upon logging in, the service sends a cryptographic challenge to the Feitian Key.
  3. Digital Signature : The Feitian Key signs this challenge with its private key and sends the signature back to the service.
  4. Authentication : The server verifies the signature with the previously registered public key and grants access if it is correct.
