Towards device independent security in quantum cryptography — •Torsten Franz and Reinhard Werner — Institut für Mathematische Physik, TU Braunschweig

Quantum cryptography enables two parties to perform private communication. Crucial for the security are the assumptions, which have to be made about the practical implementation of the theoretical protocol. In the device independent scenario one tries to consider only as few assumptions as possible, while still guaranteeing security even against the most general, i.e. coherent, attacks. We will present results on the problem in a black-box scenario.
