Arqit Quantum Inc., a global innovator in quantum-safe encryption technology, has introduced its latest advancement — the SKA Central Controller (SKA-CC). This cutting-edge software platform is designed to future-proof network security infrastructures against both existing and emerging quantum computing threats.

The SKA Central Controller is a crypto-agile, lightweight solution that enables telecommunications and defense-focused managed service providers (MSPs) to deliver quantum-safe network services without the high cost or complexity of legacy key management systems. By generating dynamic symmetric encryption keys for endpoint authentication and VPN encryption, SKA-CC removes dependence on long-term pre-shared keys and traditional PKI-based models.

Engineered for the hybrid and cloud-driven era, SKA-CC ensures that data transferred across wireline, mobile, cloud, and AI-integrated networks remains protected using scalable, efficient, and quantum-resistant cryptography.

Empowering Telecom Providers with Next-Generation Secure Services

The new platform supports an extensive array of telecommunications and network infrastructure use cases, enabling service providers to deploy advanced quantum-safe solutions across diverse environments and customer bases. Key use cases include:

  • Secure Network-as-a-Service (NaaS): Offers quantum-secure, multi-layer VPNs with multi-tenant key policy controls—ideal for automating and managing virtual network functions, Universal CPE, and Virtual Private Cloud interconnections.
  • Optical Transport (Layer 1): Integrates symmetric quantum-safe keys into OEM transport systems supporting OTNsec.
  • Carrier Ethernet (Layer 2): Establishes high-performance, quantum-safe MACsec point-to-point connections.
  • Internet Protocol (Layer 3): Enhances IPsec VPNs with symmetric key integration for quantum-safe communication.

  • Application Programming Interfaces (Layers 4–7): Strengthens TLS-based APIs with quantum-resistant encryption.
  • Mobile VPNs: Provides post-quantum secure VPN connectivity for mobile and remote workforce environments.
  • Private 5G Networks: Safeguards communication between radio access nodes and the core network.
  • IoT and OT Security: Protects data exchange between edge gateways, IoT hubs, and cloud systems—vital for industries such as energy, oil and gas, and critical infrastructure.

Through SKA-CC, telecommunications operators can differentiate their service portfolios, meet the growing demand for post-quantum security, and unlock new revenue opportunities in the evolving connected ecosystem.

Leadership Perspective

“Quantum computing represents a fundamental shift in the cybersecurity landscape,” said Scott Alexander, Chief Product Officer at Arqit. “With SKA-CC, we’re giving our partners a practical, scalable tool to secure their networks today and prepare for the challenges of tomorrow. This innovation reinforces Arqit’s mission to make advanced encryption both simple and globally accessible—empowering the telecom industry to deliver trusted, quantum-safe connectivity at scale.”
