This legislation aims to prepare the nation's information systems for the advent of quantum computers capable of breaking current encryption standards by requiring the development and implementation of post-quantum cryptography. The Director of the National Institute of Standards and Technology (NIST), in consultation with the Office of Science and Technology Policy (OSTP), is mandated to establish comprehensive guidance within 180 days of enactment. This guidance will include standards and selection criteria for procuring and deploying commercial post-quantum solutions, specifically tailored for critical infrastructure sectors , and NIST will offer collaboration and technical assistance for industry-led assessments. Furthermore, the Director of the Office of Science and Technology Policy (OSTP), in coordination with NIST, must develop a National Quantum Cybersecurity Upgrade Strategy within 360 days. This strategy will define a cryptographically relevant quantum computer, recommend standards for its identification, and provide guidelines for assessing the urgency of upgrades for each Federal agency based on critical functions and risk. It will also outline recommended performance measures for preparing, inventorying data, planning, executing, and monitoring the success of post-quantum cryptographic solutions. The bill also establishes a Post-Quantum Voluntary Pilot Program , to be set up by OSTP within 360 days, offering planning and technical support to covered entities, including Federal agencies, sector risk management agencies, and their mission partners. High-risk entities are encouraged to participate, with a requirement that at least one high-impact system of participating entities be upgraded within 18 months. Regular reports on the pilot program's progress and support provided will be submitted to appropriate congressional committees.
