How to prepare for a secure post-quantum future

The rise of quantum computing has serious implications for cybersecurity, as it could potentially compromise existing public key cryptographic algorithms. As large-scale quantum supercomputers could be available by 2030, the National Security Agency, Cybersecurity and Infrastructure Security Agency and NIST urge organizations to begin developing quantum-readiness plans including post-quantum cryptography (PQC) migration strategies. Experts advise preparing for the post-quantum era by conducting an inventory of all systems relying on cryptography, prioritizing migration efforts based on risk assessment, and urging vendors to adopt NIST-recommended post-quantum algorithms.
