The UK's National Cyber Security Centre (NCSC) has warned that Britain must undergo a significant overhaul of its cybersecurity systems to mitigate the risks posed by future quantum computers. CTO Ollie Whitehouse emphasized the urgency for organizations to prepare for this shift, as quantum computers could render existing encryption methods ineffective, leading to severe security breaches. The recommended approach is the adoption of post-quantum cryptography (PQC), which involves new encryption algorithms resistant to quantum attacks. The NCSC has outlined a timeline for a complete transition by 2035, highlighting the need for a comprehensive, long-term technological upgrade for national security.
Britain's cybersecurity systems require a colossal overhaul to defend against future quantum computers, according to the UK's National Cyber Security Centre.
Quantum computers could break current encryption methods, endangering essential security protocols for sectors like finance and military communications.
The migration to post-quantum cryptography requires a decade-long, national-scale technology change program to truly uplift our connected systems.
The UK's timeline for migrating to post-quantum cryptography aims for completion of all systems by 2035.
