Shipboard Cross Domain Secure Solutions

Submarines have many computer applications and systems to monitor real-time operational status of the mechanical systems onboard. These applications are classified at different levels and are spread across subnets in multiple security domains. The mixed domain nature of submarine networks forces applications that should operate at lower security levels to operate at higher security levels. This complicates the applications and operations, requiring slow Cross Domain Solutions (CDS) which add latency, limitations and data restrictions that can lead to redundant applications at different security levels and work arounds that can leak data. As the next-generation submarine is being designed, a new way for running cross-domain applications is being sought. Applications need to operate at lower levels, with ability to work with data from higher and lower levels. This new data filter system needs to be a secure, more dynamic CDS. ATCorp is proposing the Adaptive Cross-Domain Enabling System or ACES to meet these goals. ACES will improve overall application performance of real-time control systems for the submarine mechanical and network systems. The ACES system is applicable to other systems like navigation and weapons, and for tactical networks that combine sea, air and land network assets.
