Technical Frequently Asked Questions

🔒 How does Google implement FIDO2 security keys?

Google implements FIDO2 security keys using WebAuthn-compliant hardware tokens. These devices use public-key cryptography, storing private keys in a tamper-resistant security element (HSM). The process includes:

  1. Credential generation with elliptic curve cryptography (curve25519)
  2. Attestation during device registration
  3. Biometric verification using local device sensors
  4. Countermeasures against man-in-the-middle attacks

🛡️ What about quantum-resistant encryption?

Google is actively researching and testing quantum-resistant cryptographic algorithms. Our approach includes:

  • CRYSTALS-Kyber for post-quantum key encapsulation
  • Dilithium for digital signatures
  • CIRCL cryptographic library implementation
  • Hybrid encryption schemes for graceful transition
