Intermodal quantum key distribution (IM-QKD) enables the integration of fiber networks and free-space connections, which can be ground-to-ground links or involve satellite nodes in orbit. IM-QKD permits to extend reach without trusting any additional node, but this requires efficiently couple signal into a single-mode (SMF). We present implementation different realized Padova Vienna, exploiting km-long deployed fibers channels up 620 meters. show that such an intermodal scheme is compatible...
We report several use-case demonstrations for quantum key distribution in deployed fiber networks. The tests were carried out under real world conditions at the end-user premises using commercial QKD systems.
With recent advances on the capabilities of quantum computers and seminal work by Shor prime factorization integers with algorithms, threat is looming over public-key based cryptographic systems. Two distinct areas research – post-quantum cryptography provide technical means to secure systems against potentially powerful enough computers. As both technologies are now becoming readily available, integration in a wide range applications understand their characteristics trade-offs associated...
The OPENQKD project is demonstrating deployed QKD networks in several European cities. We present a virtual testbed that allows the user to monitor live data but also re-enact past exchange over various links, together with network simulation tool.
Quantum Key Distribution typically delivers symmetric keys to protect data in transit. For at rest the method of secret sharing describes distribution among a given number storages such way that for reconstruction only certain smaller shares is strictly required. This proven mathematically with consequence categorize be ITS matching well QKD. The research FP7-funded projects Archistar and Prismacloud [1] have been commercialized by spin-off fragmentiX subsequently used OpenQKD [2] . As...
