Existing key management systems using Quantum Key Distribution (QKD) technology are based on trusted relays in order to overcome the distance limitations of QKD solutions. This approach has a strong drawback: the attack surface of these systems is proportional to the number of the nodes, as a single compromised relay can potentially learn the keys of all users. This project will implement a different approach to integrate Twin-Field (TF) QKD in scalable infrastructure, by relying on a distributed trust architecture named Distributed Symmetric Key Exchange (DSKE). The combination of DSKE and TF-QKD allows to build a scalable network, called DSKE Net, without using trusted relays, and providing information-theoretic secure communication on a global scale. Importantly, DSKE Net will also be compatible with other Quantum Key Distribution technologies, allowing interoperability and boosting adoption.
