Colt, Honeywell and Nokia to trial quantum cryptography in space
Space-based cryptography aims to secure sensitive data from quantum threats.
Colt Technology Services, Honeywell, and Nokia have joined forces to trial quantum key distribution (QKD) via satellites to develop quantum-safe networks. The trial builds on a previous Colt pilot focused on terrestrial quantum-secure networks.
The collaboration aims to tackle the looming cybersecurity risks of quantum computing, which threatens to break current encryption methods. The project seeks to deliver secure global communication beyond the current 100km terrestrial limit by trialling space-based and subsea QKD.
Low-Earth orbit satellites will explore QKD over ultra-long distances, including transatlantic spans. The initiative is designed to support sectors that handle sensitive data, such as finance, healthcare, and government, by offering encryption solutions resistant to quantum threats.
Leaders from all three companies emphasised the urgency of developing safeguards to protect against future threats. A joint white paper, The Journey to Quantum-Safe Networking, has been released to outline the risks and technical roadmap for this new frontier in secure communications.
