We treat the security of group key exchange (GKE) in the universal composability (UC) framework. Analyzing GKE protocols in the UC framework naturally addresses attacks by maliciou...

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...
Abstract. Key exchange protocols in the setting of universal composability are investigated. First we show that the ideal functionality FKE of [9] cannot be realized in the presenc...
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...
