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 use of Protocol Enhancing Proxies (PEPs) and HAIPE encryption has traditionally been mutually exclusive. IP-layer encryption renders the upper layers, such as TCP, unavailable to the PEP. By integrating the IP layer encryption into the modem and using additive or multiplicative increase and decrease signals as bandwidth notification, signaling is provided across the cryptographic boundary to support the use of a bandwidth aware PEP in a network protected by IP-layer encryption.
