Abstract. One of the challenges within public-key based cryptosystems is providing the user with a convenient interface, while retaining security.
This work proposes an ideal functionality for secure messaging, with a user-friendly interface, and shows that, given a public key infrastructure and a ...
We propose a novel paradigm for defining security of cryptographic protocols, called universally composable security. The salient property of universally ...
