The Department of Defense, specifically the Navy, is seeking innovative solutions from small businesses through the SBIR program for the development of post-quantum cryptography (PQC) capabilities tailored for legacy hardware within the Navy Maintenance Repair and Overhaul (N-MRO) system. The objective is to assess the impact of adopting NIST-approved PQC algorithms, ensuring secure communications while evaluating performance, power consumption, and operational implications. This initiative is crucial as quantum computing poses a significant threat to traditional cryptographic methods, and the Navy aims to proactively transition its systems to mitigate these risks. Interested parties should prepare proposals for Phase I, with a base period of six months costing up to $140,000, and an option period of six months costing up to $100,000, with submissions due by September 24, 2025.
