Abstract: Military Standard 1553 (MIL-STD-1553) is a military standard that was published by the United States Department of Defense in 1973 for tactical aircraft. Despite advances in communications, many machines retain MIL-STD-1553 buses, since retrofitting the machines with newer communication systems is not always practical. However, newer subsystems for such machines tend to utilize Internet Protocol (IP) for higher bandwidth communications. Accordingly, a device is disclosed that enables IP communications over existing MIL-STD-1553 buses. This enables an existing MIL-STD-1553 bus to span the gap between two separate IP networks (e.g., subsystems) within the machine. In addition, the IP communications may utilize Standard Agreement (STANAG) 7221 to provide higher bandwidth over the existing MIL-STD-1553 buses. For added security, the IP communications may also be encrypted during transport over the MIL-STD-1553 buses.

Abstract: Systems and methods for validating a configuration-dependent algorithm of a network device under test (DUT) within a simulated wireless environment are provided. The method can include transmitting idealized configuration information to a first DUT, including at least one of zero-error geolocation information and zero-error orientation information. The method can include monitoring first data transmissions between the first DUT and a second DUT based on the idealized configuration information. The method can include determining a first link quality based on the first data transmissions. The method can include transmitting perturbed configuration information to the first DUT and determining a second link quality between the first DUT and the second DUT based on the perturbed configuration information. The method can also include evaluating the wireless system based on a comparison of the first link quality and the second link quality.

Abstract: The device and system for secure network communications disclosed herein can simultaneously operate one or more secure computing components in a single housing and integrating multiple secure networks. The device can operate networking and other software applications. The disclosed device can have physically and electromagnetically separated computing components in separate enclosures within the device, with physical attributes of the device designed to minimize spurious electronic emissions between enclosures. The device can have one or more shielded covers allowing removal and replacement of computing components within each enclosure. The device can allow simultaneous operations of multiple electromagnetically separated enclosures for multiple secure computers in a single space to integrate multiple secure networks.
