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 ...
A reasonably efficient password based key exchange (KE) protocol with provable security without random oracle was recently proposed by Katz, et al. [18] and later by Gennaro and Li...
Abstract. In this paper we present a general framework for passwordbased authenticated key exchange protocols, in the common reference odel. Our protocol is actually an abstraction...
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...
