Protocol for Cross Domain Data Flow

CDS guards provide the means to enable cross-domain applications without the risk of accidental cross contamination, but support only a limited number of communication protocols, degrade communication performance, and are vulnerable to attack themselves. We aim to address these limitations in this project. The first by designing, analyzing, and implementing one or more protocol adapters to extend CDS guards to support protocols which they were not originally designed to support. The second by offloading expensive operations from the CDS guard component. The third by exploring new CDS guard architectures and techniques to reduce the value of the CDS guard as a target and to increase the difficulty of attacking a CDS guard. The results will increase the capability and performance of CDS guard based systems in both new and legacy applications.
