Cancelable Biometrics and Quantum-Resistant Two-Factor Authenticated Key Agreement for Mobile Device
- Published
- Record updated
Summary
Researchers propose CQT-AKA, a two-factor authenticated key agreement scheme for mobile devices. The static private key is a cancelable biometric value derived by combining the user's biometrics with a password, so a leaked biometric feature can be replaced through a key update using a new password. The scheme is based on the RLWE assumption, which the authors say provides post-quantum security with lower storage and communication cost than multi-factor authentication.
