We offer cryptanalysis of a key exchange scheme due to Stickel [11], which was inspired by the well-known Diffie-Hellman protocol. We show that Stickel's choice of platform (t...
We introduce the concept of attribute-based authenticated key exchange (AB-AKE) within the framework of ciphertext policy attribute-based systems. A notion of AKE-security for AB-A...

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...

Abstract. There have been many proposals in recent years for passwordauthenticated key exchange protocols. Many of these have been shown to be insecure, and the only ones that seem...

Abstract. An authenticated group key exchange (AGKE) scheme allows a group of users in a public network to share a session key which may later be used to achieve desirable cryptogr...
