HellasQCI Demonstrates Three-Node QKD Ring Network
In a collaborative effort by GRNET, NKUA, Nokia, EvolutionQ and ID Quantique, HellasQCI has recently published a paper highlighting the successful demonstration of a fully-managed, field-deployed, three-node Quantum Key Distribution (QKD) ring network. The paper is entitled, “Field Demonstration of a Fully Managed, L1 Encrypted 3-Node Network with Hybrid Relayed-QKD and Centralized Symmetric Classical Key Management.”
The Proof-of-Concept (PoC) aims to validate HellasQCI architecture. Its network includes Layer 1 encryption at the physical layer, connecting GRNET’s and NKUA’s datacenter nodes, and covering a maximum distance of 45 kilometers.
The topology includes a 3-node full ring configuration between GRNET & NKUA, where every node is a fully integrated vertical stack featuring:
- A quantum layer
- A KMS layer
- An application layer
The network employs a hybrid scheme of QKD and classical yet quantum-safe centrally-generated symmetric keys to support point-to-point and relay consumers. In case of an attack or unavailability of quantum keys, the network’s capability to seamlessly transition to classical encryption with symmetric quantum-safe keys, exhibits a reliable hybrid network operation and ensures the continuous supply of keys.
The three-node network operated with only two QKD pairs, Cerberis XGR model, provided by ID Quantique. The full connectivity between all the nodes was obtained through the KMS, which processed and exchanged keys over the whole network. The standardized interfaces between the various elements and layers of the network (ETSI GS QKD 014 and ETSI GS QKD 015), were developed by the QKD working group of the European Telecommunication Standard Institute (ETSI). The availability of such standardized interfaces is paramount in the deployment of large, multi-provider, QKD networks, and is a clear sign of the maturity of QKD-based solutions.
Looking ahead and following the success of the PoC in Athens and the validation of the architecture, the next steps of the HellasQCI project include a large-scale deployment of the HellasQCI networks.
The HellasQCI Project
The HellasQCI project aims to deploy advanced national QCI systems and networks in Greece. The advancement in technologies that will be achieved by the realization of the HellasQCI initiative include:
- Reinforcement of scientific and technological capabilities in cybersecurity
- Improvement of industrial competitiveness
- Strengthening European digital sovereignty
This project on behalf of Greece, together with other EU Member States, the CSA project PETRUS and the European Commission will achieve the co-creation of the EuroQCI.
HellasQCI architecture comprises three metropolitan test sites located at major cities of Greece namely: ΗellasQCI-Central (Athens), HellasQCI-North (Thessaloniki) and HellasQCI-South (Heraklion-Crete).
The aim of HellasQCI is also to create a community from all interested national stakeholders, gather expertise and share knowhow on the application of quantum technologies.
About ID Quantique
ID Quantique (IDQ), founded in 2001, initially operated as a spin-off company of the University of Geneva, working on research projects to demonstrate the feasibility of quantum key distribution (or QKD, also known as quantum cryptography). In late 2003, IDQ developed the first QKD product for data centers to protect data in transit. 20 years later, IDQ released its 4th generation of quantum key distribution systems and remains the market leader in quantum safe cryptography and quantum sensing solutions. It maintains close ties with academic institutions by participating in numerous research programs and plays a leading role in cutting-edge projects to drive innovation to the market.
