The Department of Defense, specifically the Air Force Life Cycle Management Center (AFLCMC), is issuing a Request for Information (RFI) regarding an Open Architecture Cryptographic Solution. This RFI aims to gather insights from industry to support the development of a modular, high-assurance cryptographic capability that aligns with the Modular Open Systems Approach (MOSA) and Sensor Open System Architecture (SOSA) principles, addressing modernization needs within the Cryptologic Modernization Branch. The initiative is crucial for enhancing the Department of Defense's cryptographic capabilities across various operational domains, ensuring interoperability and agility in future architectures. Interested parties are encouraged to submit their responses electronically to aflcmc.cryptologic.transformation@us.af.mil by close of business on October 28, 2024, with the subject line “Open Architecture Cryptographic Solution.”
