UAuth: A strong authentication method from personal devices to multi-accounts

Abstract

In this paper we present UAuth, a two-layer authentication framework that provides more security assurances than two-factor authentication while offering a simpler authentication experience. When authenticating, users first verified their static credentials (such as password, fingerprint, etc.) in the local layer, then submit the OTP-signed response generated by their device to the server to complete the serverlayer authentication. We also propose the three-level account association mechanism, which completes the association of devices, users and services, establishing a mapping from a user’s device to the user’s accounts in the Internet. Users can easily gain access to different service via a single personal device. Our goal is to provide a quick and convenient SSO-like login process on the basis of security authentication. To meet the goal, we implement our UAuth, and evaluate our designs.
