Colt Technology Services (Colt), Honeywell and Nokia are collaborating to explore quantum-safe networking using SATCOM.
As part of the initiative, the companies are planning to test new ways of protecting encrypted optical network traffic from risks presented when quantum computing potentially breaks through traditional encryption methods, leaving data vulnerable to cyber threats.
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 faster, potentially breaking through traditional encryption methods and putting data at risk.
One promising advancement in this field is quantum key distribution (QKD), a technology central to the quantum evolution. However, QKD currently faces a major limitation: terrestrial physical constraints restrict its range to around 100 kilometers. To achieve global coverage of QKD, the technology can overcome these limitations by moving into space.
Colt, Honeywell and Nokia plan to explore quantum-safe cryptography, trialling space-based and subsea techniques which are resistant to quantum computing attacks.
The companies will trial quantum key distribution—a method used to securely share encryption keys between two parties—using LEO satellites for ultra-long distances and transatlantic reach. The three companies share a collective goal: enable customers to benefit from the huge potential of quantum computing in ways that help solve pressing challenges, while protecting them from risk.
This trial is expected to be of interest to organisations responsible for vast amounts of highly sensitive data such as financial firms, healthcare and pharmaceutical organisations and government bodies. Before the trial, Colt, Honeywell and Nokia have drafted a white paper with more detail on the risks, threats and opportunities presented by quantum cryptography.
