The Federal Aviation Administration (FAA) is seeking industry input on the transition of its National Airspace System (NAS) and enterprise IT systems to Post-Quantum Cryptography (PQC). The FAA is looking for vendors who can provide PQC solutions that meet the agency's unique safety, complexity, and longevity requirements. The transition to PQC is a critical step in ensuring the long-term security and integrity of the NAS and enterprise IT systems. The FAA is interested in learning about vendors' capabilities and experiences in implementing PQC solutions, including their approaches to key management, algorithm implementation, and system integration. The FAA is also seeking information on the potential costs and benefits of different PQC solutions, including the costs of implementation, maintenance, and support. Some key points to consider include: • The FAA's NAS is a complex system that requires a high level of security and integrity to ensure safe and efficient air traffic control. • The transition to PQC will require significant changes to the NAS and enterprise IT systems, including the implementation of new cryptographic algorithms and key management systems. • The FAA is interested in learning about vendors' experiences with PQC solutions in other industries and how they can be applied to the NAS and enterprise IT systems. • The FAA is seeking information on the potential costs and benefits of different PQC solutions, including the costs of implementation, maintenance, and support. • The FAA is looking for vendors who can provide PQC solutions that meet the agency's unique safety, complexity, and longevity requirements.
