The UK's National Cyber Security Centre (NCSC) advises organizations to implement post-quantum cryptography to safeguard against quantum hacking threats.
Quantum computers can solve complex mathematical problems underlying current encryption methods.
The NCSC recommends critical infrastructure operators and businesses with custom IT systems adopt post-quantum cryptography.
Organizations should identify services needing updates by 2028, complete major updates by 2031, and fully migrate to new encryption by 2035.
This guidance aims to protect sensitive data from future quantum computing threats.
