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 propose and realize a definition of security for passwordbased key exchange within the framework of universally composable (UC) security, thus providing security guar...
