The connection links Sparkle<\/a>\u2018s data centre in Metamorfosi, Athens, with Hellas Sat infrastructure in Cyprus, following earlier successful testing of a secure IPsec connection between two data centres in Greece. The latest trial extends that protection to a live satellite connection between the two countries, with data travelling approximately 72,000 kilometres through the satellite system, including the uplink from Cyprus to the satellite and the subsequent downlink to Greece.<\/p>\n According to the companies, this marks the first application of this specific form of quantum protection to a Greece-Cyprus satellite link.<\/p>\n The link runs on Sparkle\u2019s Quantum Safe Interconnect (QSI) system, built to counter what\u2019s known as the \u201cstore now, decrypt later\u201d risk: data intercepted and stored today, with the expectation that future computing power will eventually crack its encryption, the outlet reported.<\/p>\n QSI works by transmitting data securely while automatically rotating encryption keys. Because the system is software-based, it can be layered onto networks and security infrastructure that already exist, meaning companies can upgrade their protection site by site without ripping out current systems.<\/p>\n For readers looking to understand \u201cstore now, decrypt later\u201d in more depth, TQI\u2019s coverage of why the harvest-now-decrypt-later threat creates urgency today<\/a> and how quantum computing affects modern cryptography<\/a> covers the mechanics of the threat and what organizations are doing to prepare.<\/p>\n Company Statements<\/p>\n \u201cThe extension of QSI to satellite communications with Hellas Sat demonstrates in practice that this technology can be applied everywhere, on terrestrial networks, satellites and across different environments,\u201d said Antonella Sanguineti, Sparkle<\/a>\u2018s head of Networking, Cloud, Security & Identity Solutions, as cited by the Cyprus Mail. \u201cThis opens new prospects for protecting communications for organisations and companies that require highly secure and resilient connectivity in remote areas,\u201d she added.<\/p>\n The outlet noted that the achievement carries particular weight for Cyprus given Hellas Sat\u2019s role in delivering communications infrastructure from the island.<\/p>\n![\"Introducing](\"https:\/\/www.newsbeep.com\/ie\/wp-content\/uploads\/2026\/09\/1788374050_947_Option-1-1-1.png\")
