This paper presents a secure constant-round password-based group key exchange protocol in the common reference string model. Our protocol is based on the group key exchange protoco...
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. 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 present a general framework for passwordbased authenticated key exchange protocols, in the common reference odel. Our protocol is actually an abstraction...
Abstract. We propose and realize a definition of security for passwordbased key exchange within the framework of universally composable (UC) security, thus providing security guar...
