The Post Quantum Cybersecurity Standards Act aims to amend existing legislation to accelerate the adoption of post-quantum cybersecurity standards across the United States economy. It seeks to support cryptography research, define post-quantum cryptography as methods resilient to quantum and classical attacks, and direct NIST to promote voluntary adoption and deployment of these standards. The bill also proposes a grant program to assist entities, including critical infrastructure and digital infrastructure providers, in implementing these advanced cryptographic solutions.
