Sparkle and Hellas Sat have activated what they describe as the first quantum-safe satellite connection linking Greece and Cyprus. The infrastructure connects Sparkle's data centre in Metamorfosis, Athens, to Hellas Sat's Cyprus operations via a geostationary satellite path spanning approximately 72,000 kilometres in total distance.
The deployment follows an earlier successful trial in which the two organisations demonstrated quantum-safe IPsec connectivity between two Greek data centres. The companies have now extended this same security layer to live satellite operations.
Sparkle's Quantum Safe Interconnect (QSI) technology employs secure key delivery mechanisms and continuous encryption key rotation to safeguard sensitive data. The solution integrates with existing network and security infrastructure, enabling organisations to adopt quantum-safe protections across multiple locations without requiring wholesale replacement of current systems.
Antonella Sanguineti, Head of Networking, Cloud, Security & Identity Solutions at Sparkle, stated: "The extension of QSI to satellite connectivity with Hellas Sat represents a concrete step in the evolution of our quantum-safe portfolio. It demonstrates that QSI can be deployed consistently across different network layers, connectivity domains, and operational environments, opening new opportunities to protect communications for customers requiring secure, resilient connectivity across geographically distributed environments."
Constantinos Kassianides, Director of Ground Operations at Hellas Sat, added: "This successful implementation marks another important milestone in our collaboration with Sparkle. By combining our satellite infrastructure with Sparkle's QSI solution, we can now evaluate the commercial deployment of quantum-safe satellite services for enterprise customers operating across distributed, remote, and mission-critical locations."
