UK Cybersecurity Agency Warns of Quantum Computing Threats, Urges Transition to Post-Quantum Cryptography by 2035

The UK's National Cyber Security Centre (NCSC) has issued guidance urging organizations to prepare for quantum-powered cyber attacks. Key points: * Firms are encouraged to adopt post-quantum cryptography (PQC), a novel encryption method. * Quantum computers could bypass existing encryption, threatening secure communications and critical data. * Organizations should identify cryptographic services needing upgrades within three years. * High-priority upgrades should be executed by 2031. * All security systems should migrate to PQC by 2035. * Transition to PQC security will give the UK the opportunity to tap into its deep pool of technical expertise to lead the world in quantum security through early adoption of the new standards. This guidance aligns with US advice on preparing for quantum threats. The transition to new cryptographic standards is considered a significant technological shift.
