Lattice-Based Remote User Authentication from Reusable Fuzzy Signature

Abstract: In this paper, we introduce a new construction of lattice-based reusable fuzzy signature for remote user authentication that is secure against quantum computers. We define formal security models for the proposed construction, and we prove that it can achieve user authenticity, biometrics reusability and user privacy. In particular, the proposed new construction ensures that: 1) biometrics reusability is achieved such that fuzzy signatures remain secure even when the same biometrics is reused multiple times; 2) a third party having access to the communication channel between an authorized user and the authentication server cannot identify the authorized user.
