Post Quantum Cybersecurity Standards Act

HR 5759, the Post Quantum Cybersecurity Standards Act, directs the National Institute of Standards and Technology (NIST) to promote voluntary adoption of quantum-resistant encryption standards. It specifically targets critical infrastructure operators and digital infrastructure providers at high risk of quantum computer attacks. Key mechanisms include NIST developing public guidance and technical assistance, and establishing a grant program to fund adoption costs for eligible high-risk entities. The bill defines "post-quantum cryptography" as encryption methods resistant to both quantum and classical computer attacks. This legislation aims to prepare U.S. systems for future quantum computing threats without mandating compliance.
