Distributed Symmetric Key Exchange Network (DSKE Net)
FY 2024-25 · 2024-11-04
Summary
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 DSK

Description
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.

Description (French)
Les systèmes actuels de gestion des clés qui utilisent la technologie de distribution quantique de clés (QKD) sont basés sur des relais fiables afin de pallier les limitations des solutions QKD sur le plan de la distance. Cette approche présente toutefois un inconvénient majeur : la surface d’attaque de ces systèmes est proportionnelle au nombre de nœuds. En effet, un seul relais compromis peut potentiellement mener à la découverte des clés de tous les utilisateurs. L’objectif de ce projet est de mettre en œuvre une approche différente pour intégrer la QKD à double champ (TF-QKD) dans une infrastructure évolutive, en faisant appel à une architecture de confiance distribuée appelée « échange de clés symétrique distribué » (DSKE). La combinaison de DSKE et de TF-QKD permet de construire un réseau évolutif, appelé DSK.
Expected Results
In the short term, anticipated outcomes will be strengthened collaborations across industry, academia, and government to support research excellence. In the medium term, anticipated outcomes will be the development of new and potentially disruptive technologies with collaborators. In the long term, find collaborative solutions to public policy challenges and create stronger innovation systems.
Expected Results (French)
À court terme, les résultats prévus seront des collaborations renforcées entre l'industrie, le milieu universitaire et le gouvernement pour soutenir l'excellence en recherche. À moyen terme, les résultats attendus seront le développement de nouvelles technologies potentiellement perturbatrices avec des collaborateurs. À long terme, trouver des solutions collaboratives aux défis des politiques publiques et créer des systèmes d'innovation plus solides.
