We propose a new password-based 3-party protocol with a formal security proof in the standard model. Under reasonable assumptions we show that our new protocol is more efficient t...
This paper considers the problem of password-authenticated key exchange (PAKE) in a client-server setting, where the server authenticates using a stored password file, and it is de...

Abstract. We describe a public-key encryption scheme based on lattices — specifically, based on the hardness of the learning with error (LWE) problem — that is secure against ...
Abstract. In this paper we revisit one of the most popular passwordbased key exchange protocols, namely the OKE (for Open Key Exchange) scheme, proposed by Luck in 1997. Our result...
Typical protocols for password-based authentication assume a single server which stores all the information (e.g., the password) necessary to authenticate a user. Unfortunately, a...
