The Looming Quantum Threat: NCSC Urges Encryption Upgrades

The National Cyber Security Centre (NCSC) has published guidance urging businesses to transition to quantum-resistant encryption methods by 2035. While the commercial availability of quantum computers capable of cracking traditional cryptography is estimated to be five to ten years away, experts emphasize the urgency of preparing for this threat. Implementing post-quantum cryptography (PQC) requires a top-down approach involving a cross-disciplinary team to inventory cryptographic assets and prioritize mitigation strategies.
