We give a new, simulation-based, definition for security in the bounded-quantum-storage model, and show that this definition allows for sequential composition of protocols. Damg...
Abstract. We propose an asynchronous protocol for general multiparty computation with perfect security and communication complexity O(n2 |C|k) where n is the number of parties, |C|...
Group key exchange protocols allow their participants to compute a secret key which can be used to ensure security and privacy for various multi-party applications. The resulting g...
Abstract—The World Wide Web offers easy sharing of information, but provides only few options for the protection of sensitive information and other sensitive resources. Tradition...
