UK's NCSC Urges Organizations to Migrate to Post-Quantum Cryptography by 2035 to Counter Quantum Computing Threats

The UK's National Cyber Security Centre (NCSC) advises organizations to transition to post-quantum cryptography (PQC) by 2035 to protect against future quantum computing threats. * A phased approach is recommended for a smooth migration, minimizing security gaps. * Large organizations should create migration plans within 2-3 years. * Priority migration activities should be completed in the subsequent 2-3 years. * Full migration should be completed by 2035, incorporating new cryptographic technologies. * The US National Institute of Standards and Technology (NIST) standardized PQC algorithms in 2024. * Microsoft unveiled Majorana 1 quantum chip in February 2025, aiming for million-qubit scaling. * Vendors have validated PQC algorithm implementations via NIST's program. * Google Cloud KMS offers quantum-safe digital signatures for software keys. * Cloudflare introduced PQC protections in its zero trust platform in March 2025.
