How Businesses Can Safeguard Operations From Quantum ThreatHow Businesses Can Safeguard Operations From Quantum Threat

Recent advances in quantum computing, sensing and communications capabilities promise to deliver a step-change in digital infrastructure and services across industries, societies and governments. At the same time, such developments create a risk of shielding digital information through the threat of attack by a cryptographically relevant quantum computer (CRQC).

Such capabilities will render most current encryption methods obsolete, with devastating consequences. The industry is realizing that it can no longer rely on a single cryptography layer. As the emergence of CRQC becomes more likely, so does the urgency to safeguard sensitive data, critical infrastructures and national security. The much-needed response requires a multi-layered, defense-in-depth approach, yet with the flexibility to adapt to the evolution of quantum computing.

In addition to recent developments in post-quantum cryptographic (PQC) standardization at the application layer, quantum-safe networking (QSN) is becoming a beacon in the connected digital age. This is where we marry the quantum-resistant encryption techniques with networking technologies, to ensure that any data traversing the quantum-safe networks can withstand the might of quantum computers against any attempts of eavesdropping and deciphering.

This is also where we depart, for some types of connections, from traditional mathematics-based cryptography to physics-based cryptography, whether valuable information traverses within enterprise campus networks, across multiple government and defense locations, or from one country to another across the European Union, and the globe. Quantum-Safe Networks will become the key enabler to achieve NIS2 ambitions for data-in-flight.

This will be embedded in all mission-critical networks across Europe, including public telecommunications infrastructure, government, defense, finance, healthcare and power utilities – wherever data confidentiality is paramount. Whether protecting national security or ensuring the integrity of our digital economies, QSN establishes itself as a quantum-safe haven.

This journey has already started with telecom service providers across Europe and will continue to expand into mission-critical networks across industries and verticals throughout the region.
