White Paper: Sensors/Data Acquisition
Cloud-Scalable Cross-Domain Solutions for an Evolving Battlefield
SPONSORED BY: ![]()
The need to transfer information between defense systems is overlaid with the need to restrict information transfer based on security classifications. Information approved for a given security domain should only be transferred to systems authorized for that domain. Cross-domain solutions (CDS) are mechanisms for implementing appropriate transfers based on a defined security policy but reliance on software makes these CDS vulnerable to cyberattacks, while the centralized model limits their usefulness with high-bandwidth, many-sensor data streams. The next generation of CDS will look very different, delivering more security, higher performance, and greater flexibility. Learn about The traditional centralized CDS implementation, downsides, and security vulnerabilities, and how a bookend CDS model using FPGAs that will mitigate cyberattacks.

Overview
The white paper titled "Cloud-Scalable Cross-Domain Solutions for an Evolving Battlefield" by Mercury Systems discusses the critical need for secure and rapid information transfer between defense systems in modern military operations. It highlights the challenges posed by traditional centralized Cross-Domain Solutions (CDS), which often struggle to manage the increasing volume of data generated by intelligent sensors and artificial intelligence (AI) applications. These centralized systems, reliant on racks of processors, are vulnerable to cyberattacks and cannot efficiently handle the flexible network connections required for real-time responses.
To address these challenges, the paper introduces a new approach known as the "bookend model" for CDS. This model decentralizes security decision-making, placing it at the endpoints of each connection, which enhances flexibility and reduces the risk of a single point of failure. The use of field-programmable gate arrays (FPGAs) as endpoints is emphasized, as they can provide robust security without the vulnerabilities associated with software. FPGAs enable high-bandwidth data processing and can adapt to various communication protocols, making them suitable for edge deployments.
The paper outlines several key requirements for the next generation of CDS, including enhanced security against cyberattacks, support for low-latency data movement, and the ability to impose security rules on diverse data transfers. It also emphasizes the importance of faster certification processes for secure performance.
Mercury Systems, as a participant in the DARPA Guaranteed Architecture for Physical Security (GAPS) program, is actively developing these advanced CDS technologies. The company aims to collaborate with defense prime contractors to deploy these innovative solutions, ensuring that they meet the evolving demands of battlefield communications while maintaining high security and performance standards.
In summary, the white paper presents a forward-looking vision for CDS that leverages cutting-edge technology to enhance the security and efficiency of military communications in an increasingly complex operational landscape.
