Traditional encryption methods, or cryptography, rely on complex mathematical problems that are difficult for computers to solve, but quantum computers are expected to solve these problems much faster, potentially breaking traditional encryption methods and compromising data. One promising advance in this field is quantum key distribution (QKD), a fundamental technology for quantum evolution. However, QKD currently faces a major limitation: terrestrial physical constraints limit its range to about 100 kilometers. To achieve global coverage for QKD, the technology can overcome these limitations by moving into space. Colt, Honeywell, and Nokia plan to explore secure quantum cryptography, testing space-based and underwater techniques that are resistant to quantum computing attacks.
The companies will test quantum key distribution, a method used to securely share encryption keys between two parties, using low Earth orbit satellites for ultra-long distances and transatlantic reach. The three companies share a common goal: to enable customers to benefit from the enormous potential of quantum computing to help solve urgent challenges, while protecting them from risks. The trial is expected to be of interest to organizations responsible for large amounts of highly sensitive data, such as financial institutions, healthcare and pharmaceutical organizations, and government agencies.
“The collaboration between Colt, Honeywell, and Nokia is based on a shared passion and determination to push the boundaries of technology to find solutions that protect our customers and help them succeed. At Colt, we do everything we can to make our customers’ lives easier. That’s why we’re taking steps now to protect them from future cybersecurity risks, addressing tomorrow’s threats today,” said Buddy Bayer, Chief Operating Officer of Colt Technology Services.
“With more than five decades of experience in the aerospace industry, Honeywell has witnessed and adapted to the evolution of the global communications landscape. We are proud to continue leading the way in innovating future-proof solutions, such as the QEYSSat and QKDSat missions for the quantum age. This collaboration represents a significant step forward in future-proofing critical data: designing solutions to enhance resilience and ensure the long-term security of data in critical communications infrastructure and systems,” said Lisa Napolitano, Vice President and General Manager of Space at Honeywell Aerospace Technologies.
“Nokia helps our customers stay ahead of the curve in protecting critical data through resilient defense-in-depth strategies. Quantum computing holds immense promise, but it also poses a potential threat to the encryption models that society has relied on until now. This collaboration with Colt and Honeywell demonstrates how secure, space-based quantum technologies can help protect networks and safeguard sensitive information across the board against future quantum threats,” said James Watt, Vice President and General Manager of Optical Networks at Nokia.
Ahead of the test, Colt, Honeywell, and Nokia have produced a white paper detailing the risks, threats, and opportunities presented by quantum cryptography. The document, titled "The Journey to Quantum-Safe Networking," is available here.
