Abstract: A secure network interface system includes a secure domain interface, a processing system, a network function device, and a network interface. The processing system is configured to send and receive information within secure systems, transmit configuration data for the network interface, compile data from the secure systems into a plurality of data packets, and transmit the plurality of data packets to the network function device without being physically capable of receiving data packets from the network function device, thus providing a demonstration of security partitioning. The network function device receives the configuration data, configures the network interface using the configuration data, and provides discrete feedback to the processing system regarding a configuration status. The network interface sends the plurality of data packets to one or more external unsecure systems and to limits a communication protocol type received from one or more external unsecure systems.
