Résumé
Passkeys are a passwordless authentication method that is increasingly being adopted. Based on asymmetric cryptography, they offer a secure and promising alternative to traditional passwords. In this paper, we propose a new secure approach for passkey synchronization based on a Peer-to-Peer mechanism between devices. Our secure services integrates biometric authentication via fingerprint or facial recognition, Wi-Fi Direct and QR codes. Also our secure approach use Elliptic Curve Diffie-Hellman algorithm for secure key exchange and Zero-Knowledge Proofs for mutual authentication in passkey system. This approach ensures the confidentiality and integrity of passkeys while eliminating reliance on central servers and strengthening protection against Man-in-the-Middle attacks and identity spoofing.
