Sparkle, Italy’s largest international telecommunications provider, and Hellas Sat have announced the successful implementation of the first quantum-secure satellite connection between Greece and Cyprus. This achievement marks a new era in data security, extending advanced protection from terrestrial networks into space.
A 72,000-Kilometer Journey
The test was conducted over a live satellite link connecting Sparkle’s data center in Metamorfosi, Athens, with Hellas Sat’s infrastructure in Cyprus. Data traveled a total distance of approximately 72,000 kilometers, encompassing the uplink from Cyprus and the downlink in Greece. This represents the first time such quantum protection has been applied to a satellite link between the two nations.
Quantum Safe Interconnect Technology
Sparkle’s Quantum Safe Interconnect (QSI) solution is designed to counter the "harvest now, decrypt later" threat. In this scenario, malicious actors intercept encrypted data today with the intent of decrypting it in the future using more powerful quantum computers. As a software-based solution, QSI allows for automatic encryption key rotation and seamless integration into existing infrastructures.
"The expansion of QSI to satellite communications demonstrates in practice that this technology can be applied everywhere: on terrestrial networks, satellites, and in different environments," stated Antonella Sanguineti, Head of Networking, Cloud, Security & Identity Solutions at Sparkle.
Commercial Prospects and Regional Impact
Konstantinos Kassianidis, Director of Ground Operations at Hellas Sat, noted that this milestone paves the way for the commercial availability of quantum-secure services for enterprises operating in remote or critical locations. This development further solidifies Greece’s role as a testing and development hub for next-generation security technologies in Europe.
