The National Institute of Standards and Technology (NIST) has announced that current public-key cryptography will be replaced by a new post-quantum cryptographic standard.
Current public-key cryptography is vulnerable to quantum-based attacks, necessitating the transition to a new standard. NIST will not publish the new post-quantum cryptographic standard for use by commercial products until 2024; however, NIST and the Cybersecurity and Infrastructure Security Agency (CISA) strongly recommend that organizations start preparing for the transition now by following the Post-Quantum Cryptography Roadmap.
CISA and NIST also advise users and administrators review the following resources for additional guidance and background:
