CHEDDAR Hub

The quantum information group collaborates within the CHEDDAR hub, an EPSRC initiative aiming to bring together researchers to work out solutions to advance innovations in cloud computing systems. The hub connects experts across academic, business, and international communities.

In York, we explore possibilities for new adversarial threats and quantum-secure solutions for communications systems and infrastructure that may find applications in the forthcoming years, like quantum networks and its integration with IoT devices.
In fact, the continuous improvement of the computational power of quantum computers, witnessed during the latest years, demands an update of solutions designed to secure our current communication infrastructures (internet, sensor, mobile devices, autonomous vehicles), to preserve privacy and security in a quantum era, when powerful quantum computers may be used to compromise current communication networks. 
Such solutions require the development of Quantum Key Distribution (QKD) systems and the integration of QKD systems with more traditional post-quantum cryptographic (PQC) solutions. 

Within CHEDDAR we develop research on both these aspects studying PQC performance and benchmarking their usability with constrained devices, like for example IoT systems, developing QKD protocols, quantifying their performance and limitations, considering scenarios for wired, wireless and hybrid communications systems.
One of the main research goals is to study the usability of quantum key distribution in communication scenarios where senders and receivers may be characterised by limited computational power and small storage (memory) capability, such we may find in IoT devices.

The research is strongly interdisciplinary bringing together expertise from Computer Science, Mathematics, Physics and Engineering departments.
