Moreover, we show that a signcryption protocol realizes the signcryption functionality if and only if the corresponding signcryption scheme is secure. Download ...
Moreover, we show that a signcryption protocol realizes the signcryption functionality if and only if the corresponding signcryption scheme is secure.
Aug 27, 2014 · This paper analyzes group communication within the universally composable framework. We first propose the group communication model, identity- ...
Aug 15, 2004 · The reason that this ideal-model based analysis of signature schemes is attractive is that it provides very strong secure composability ...

We propose a novel paradigm for defining security of cryptographic protocols, called universally composable security.
We extend the notion of universally composable (UC) security in a way that re-establishes its original intuitive guarantee even for protocols that use globally ...

Universally Composable (UC) protocols provide this guarantee in a strong sense: A protocol re- mains secure even when composed concurrently with an un- bounded ...
Oct 15, 2009 · Abstract. The Universal Composability model (UC) by Canetti (FOCS 2001) allows for secure composition of arbitrary protocols.
