Arqit Launches Encryption Intelligence: Automated Cryptographic Discovery for Post-Quantum Migration and Compliance Arqit announced the full commercial launch of Encryption Intelligence (EI), a product that delivers a complete cryptographic inventory, alongside continuous discovery and risk prioritisation to help enterprises plan and execute migration to post-quantum cryptography (PQC) efficiently and with minimal disruption. Migration to quantum-safe encryption will be the biggest IT transformation of the coming decade. Encryption Intelligence gives deep awareness of encryption dependencies to enable an efficient and effective PQC migration programme. This is particularly important as many organizations lack a complete and accurate view of their existing cryptographic dependencies. Legacy algorithms and deprecated protocols frequently persist for years after they should have been retired, especially across cloud services, acquired systems, operational technology and long-lived infrastructure. What Encryption Intelligence Delivers: Excover obsolete or weak encryption in real time across networks, applications and cloud services. Accelerate Secure Migration: Gain the insight to inform the roadmap required to replace legacy encryption and future-proof organization against emerging and quantum threats. Stay Secure, Always: Continuously monitor and optimise encryption landscape to ensure lasting protection and compliance. The focus on discovery and prioritisation is emblematic of a broader shift in regulatory and advisory thinking. National and international bodies increasingly emphasise cryptographic discovery and inventory as the first practical step towards post-quantum readiness. Arqit has been selected by the UK National Cyber Security Centre (NCSC) to participate in its Post-Quantum Cryptography Pilot under the Assured Cyber Security Consultancy Scheme. The programme validates the strength of Arqit's discovery and migration planning methodology, and its effectiveness at helping organizations understand their current cryptographic exposure. 공시 • Jan 14

Arqit and Sparkle achieve quantum-resistant encryption at the speed of light Arqit Quantum Inc. and Sparkle demonstrated quantum-resilient data transmission across Sparkle’s optical network in Greece. The proof of concept (POC), implemented over Sparkle metropolitan optical ring in Athens, shows how Arqit’s encryption technology can be embedded directly into the optical transport layer, protecting high-capacity networks against future quantum threats without impacting performance.Sparkle validated that sensitive data can be secured at the physical network layer without compromising performance. Following the deployment of Arqit’s technology, end-to-end encryption was successfully applied to multi-100G optical links. This demonstrated that quantum-resistant protection can be delivered at the speed of light, ensuring ultra-secure data transmission without compromising performance. Key Highlights: Optical-Layer Quantum-Safe Encryption: Sparkle’s Quantum-Safe over Internet (QSI) solution operates directly on optical transponders, integrating Arqit SKA-Platform™ encryption into the physical layer (L1).High-Capacity and Scalable: supports multi-100G optical links and scales with growing network demands.No physical changes to optical hardware: offers a practical, ready-to-deploy solution that doesn’t require expensive optical hardware changes. The quantum-safe symmetric encryption key was injected from VM and universal CPE appliances, connected to ETSI14 Interface and managed via the Orchestration platform. 공시 • Dec 01
