Fuzzy password-authenticated key exchange
WebTo address this issue, it has been suggested to share a userʼs password information among multiple servers, and to have these servers cooperate (possibly in a threshold manner) when the user wants to authenticate. We show here a two-server version of the password-only key-exchange protocol of Katz, Ostrovsky, and Yung (the KOY protocol). WebDec 5, 2024 · Abstract. Password-Authenticated Key Exchange (PAKE) lets users with passwords exchange a cryptographic key. There have been two variants of PAKE which …

Building a \textsf {fPAKE} from YGC and OT is not straightforward, since all constructions of OT assume authenticated channels, and fPAKE (or PAKE) is designed with unauthenticated channels in mind. We therefore follow the framework of Canetti et al. [18], who build a UC secure PAKE protocol using OT. … See more In Sect. 3.1.1, we briefly review oblivious transfer.

Webing because fewer bits means less entropy in a shared key, easing an offline attack. To address this challenge, we adapt a recently introduced Fuzzy Password-Authenticated Key Exchange (fPAKE) protocol [10]. fPAKE establishes a shared key from low-entropy se-crets (e.g., short passwords) and is resistant to offline attacks.
