The WiN-Lab develops software and tools on behalf of the DFN. Additionally it investigates topics important for the future of the X-WiN. The X-WiN is the German research network which is carried by the DFN. This network connects universities, research institutions and research-related companies in Germany with each other, as well as with scientific networks in Europe and other continents. With connection capacities of up to 200 Gigabit/s and a multi-terabit core network, X-WiN is one of the most powerful communication networks worldwide. Funded by the DFN-Verein, the WiN-Labor has been located at the Regional Computing Center (RRZE) of the University of Erlangen-Nuremberg since 1992 with the start of the then “2-Mbit-WiN-Labor Project”.
Currently, the WiN-Lab is mainly engaged in research on quantum networks and techniques for time synchronization in the network.
Besides the mere generation of quantum-safe keys by Quantum Key Distribution (QKD), the further procedure with the keys, such as storage, management, and distribution to the target applications just in time, also plays a major role in the ongoing security. Often, this equally important field is stil...
The Quantum Key Distribution (QKD) has limits, especially regarding distances. However, general useability has been shown in the context of large (scientific) testbeds. International standards are available. There already exist products that are suitable for normal operational/technical environments...
The ongoing development of quantum computers affects the security of currently used encryption and authentication schemes. Therefore, this document presents 'Post Quantum Cryptography' (PQC) and 'Quantum Key Distribution' (QKD). PQC describes software based approaches for quantum safe encryption and...
Before a new technology can be commercially used on a large scale, first some practical experience has to be obtained. This is usually done in testbeds, where commercial hardware is used under realistic conditions.
Quantum Key Distribution (QKD) facilitates the generation of common secret random nu...
