Lillian Kråkmo · NORA - Norwegian Open Research Archives · 2009
One of the challenges within public-key based cryptosystems is providing the user with a convenient interface, while retaining security. In the framework of universally composable security, we propose an ideal functionality for secure messaging, with a user-friendly interface. We also show how to realize it using a cryptographic primitive and a public key
