Post Quantum Cryptography Support for FAA Information Technology and National Air Space Systems

The FAA has issued RFI 697DCK‑26‑RFI‑PQC to gather industry data and innovative approaches for transitioning both the National Airspace System (NAS) – including ATC infrastructure – and FAA business systems to Post‑Quantum Cryptography (PQC). Respondents must detail their capabilities across IT, OT, or integrated environments, covering algorithm implementation (NIST‑selected PQC suites, security levels, versioning), cryptographic agility, safety‑critical architecture (sub‑millisecond latency, ground‑to‑ground links, RTCA DO‑178C/DO‑254 compliance), legacy system isolation (e.g., cryptographic gateways), and a phased deployment plan that minimizes operational disruption. Answers to the specific questions in Section 3, along with any clarifying assumptions or concerns, must be submitted electronically to the listed points of contact by 4:00 PM ET on April 24 2026; the response (excluding cover, TOC, corporate background, and glossary) may not exceed 30 pages and must follow the prescribed formatting. This is an information‑only solicitation—no proposals will be accepted, no costs will be reimbursed, and the Government will not answer questions about the RFI.
