UBDM is a digital modulation designed to diminish the total attack surface of networks by blocking the wireless link. Digital modulation involves the conversion of complex baseband I/Q symbols into different complex baseband points and passing them by an analog front-endfront end through which they are filtered, upconverted, and transmitted. UBDM operates at the OSI physical layer, encrypting transmitted information by taking symbols as input and producing different symbols as output. ResultantlyAs a result, traffic is indecipherable by unintended recipients and cannot be interfered with or modified.

• Stability: UBDM has no hidden requirements such as filtering, wideband front-endsfront ends, or precise timing, benefittingwhich benefits device stability and synchronization.

• Noise-smoothing: Filtering is simplified and the cost of analog hardware is reduced as the UBDM receiver transforms all noise (von Mises/Tikhonov distributions, phase noise, etc.) to Gaussian.

• UBDM satisfies the criterion of Kerckhoffs' principle (also known as Kerckhoffs’ law or Shannon’s maxim), which states that the security of a cryptosystem must lie exclusively in its key. Everything else, including the algorithm, should be considered public knowledge and not bear upon the system’s security.

Rampart provides direct integration support services. Hardware architecture, upper-layer protocols, and network topology of the subject system must first be assessed,; however, the company claims that the integration process is relatively uncomplicated. The most straightforward way of integrating UBDM is through SDR (software-defined radio) platforms. Rampart Communications’ SDR build is a C++11 library linked to the C++ standard library and coded according to the SEI CERT C++ Coding Standard.
