Communications Security (COMSEC)

The Communications Security (COMSEC) program within the Army is dedicated to ensuring secure battlefield communications by maintaining the capability to operate at National Security Agency (NSA) classification levels of SECRET and TOP SECRET. It is divided into two main sub-programs: COMSEC Cryptographic Systems (CCS) and Army Key Management Infrastructure (AKMI).

The primary objective of the CCS is to procure and field NSA-approved products that encrypt communications, preventing adversaries from decrypting, eavesdropping, or distorting soldier communications. This includes a range of products from high-capacity network encryptors for military bases to secure phones for individual use.

The Army Key Management Infrastructure (AKMI) aims to deliver cryptographic keys necessary for encrypted communications. It involves managing, controlling, planning, and distributing these keys through various components such as the Management Client Nodes, Over the Network Key software, and Simple Key Loaders. AKMI's goal is to automate key distribution processes, reducing manual intervention by soldiers and ensuring seamless communication across tactical and strategic networks. The program also supports the procurement of new devices like advanced key loaders with enhanced capabilities.

A significant component of COMSEC's modernization efforts is the focus on replacing legacy systems with devices that support cryptographic re-programmability and are upgradable to meet NSA's Cryptographic Modernization 2 algorithms. This initiative ensures that the Army's communication infrastructure remains resilient against evolving threats while enhancing operational efficiency through improved automation and reduced manual oversight.

The Communications Security (COMSEC) program plays a crucial role in maintaining secure military communications by procuring advanced encryption devices and streamlining key management processes. By investing in modern cryptographic systems and infrastructure, it seeks to enhance national security capabilities while supporting both active and reserve components in their defense missions.
