The U.S. Army relies on numerous ground vehicles for successful operations, requiring vehicles that can navigate a variety of terrains and allow soldiers to be effective and safe. This creates a challenging set of requirements for new vehicle design, engineering, and operations that must be cost-effective.

��AV is now an important contributor for researching novel approaches and development of new vehicles, thanks to a $1.6 million grant from the National Center for Manufacturing Sciences under Digital Enterprise Technology for Maintenance and Sustainment Improvements—Phase II effort, sponsored through the Army’s Ground Vehicle Systems Center.

The George Mason project, called DELTA-FORCE (Digital Environments for Life-Cycle Test and Evaluation For Off-Road Combat VEhicles), is a joint effort between the College of Engineering and Computing’s (CEC) Center for Excellence in Command, Control, Communications, Computing, Cyber, and Intelligence and the College of Science’s Center for Collision Safety and Analysis. Ali Raz of the Systems Engineering and Operations Research (SEOR) Department is the principal investigator (PI) and Steve Kan, a professor in Mason Science, is the co-PI.

This project aims to develop a comprehensive digital engineering methodology for new vehicle concepts. “It's a very unique opportunity for George Mason in that we're going to be building a complete digital environment for life cycle testing and analysis," Raz said. "Life cycle elements have their own domain-specific models, and analysis tools that are not linked. We are building a digital environment to connect them.”

The different phases of the vehicle life cycle, from conceptual design, preliminary design, detailed design, manufacturing, and maintenance, each have their own models and analysis tools that do not “talk” to one another. A key aspect of this project is creating an ontology and model-based systems engineering (MBSE) foundation that will connect the different domain-models, providing a common language for integrating the models and building interfaces in a digital environment.

“In order to produce new advanced complex systems, we need to transition into digital environments; the Department of Defense has been laying the groundwork for that for five years or so,” said Raz. “So essentially we will build a digital twin for modeling the off-road vehicle and environments, that is connected to a physical twin via reverse engineering.”

Kan said that “This project will enable us to work in the digital engineering field in a holistic way by integrating different system-level requirements, design, and performance, to the physics level of materials and geometry using reverse engineering technologies. In this project, we build upon our expertise in automotive and aerospace safety engineering and collaborate with colleagues in both CEC and Mason Science at George Mason to develop this digital engineering platform.”

Raz added that DELTA-FORCE will provide an opportunity through new undergraduate courses for George Mason students to get hands-on experience in building digital twins and conducting analysis.

Military 5G gets a security boost with anti-jamming research

Military 5G gets a security boost with anti-jamming research Teresa Donnellan Mon, 10/21/2024 - 15:01

As communication networks evolve, they present both opportunities and security challenges to military technicians. Over the past year, Assistant Professor Moinul Hossain from ��AV’s Department of Cyber Security Engineering has contributed to a research initiative aimed at ensuring the safety and integrity of 5G networks used by the United States military. Sponsored by the Army Research Laboratory (ARL) and led by the University of Maryland (UMD), the project focused on safeguarding military communications against potential threats such as jamming attacks.

Hossain’s colleagues will present their work, a research paper titled “Phantom Guard: An MDP-Based Anti-Jamming Defense Strategy for Military 5G Networks,” at the end of this month at the Institute of Electrical and Electronics Engineers (IEEE) Military Communications Conference (MILCOM). As Hossain will be on leave during the conference, George Mason doctoral student Mahmudul Hassan Ashik, who contributed to the project, will join ARL’s Jeffrey Twigg and Fikadu Dagefu and UMD colleagues for the presentation.

"As 5G technology becomes a cornerstone of global communications, safeguarding its security within military applications is crucial,” said Ashik, who is working on a PhD in cyber security engineering. “Our research tackles these complex challenges of protecting sensitive data transmitted over 5G networks in high-risk, adversarial environments."

While commercial 5G is already widely used for communication between devices, the military’s adoption of this technology necessitates additional measures to safeguard sensitive data and ensure secure communication, even in contested environments. Hossain’s project, which began in May 2023 and concluded in August 2024, centered on addressing this critical security concern.

"5G is a major pillar of national security, alongside emerging technologies like artificial intelligence and quantum computing,” Hossain explained. “Its high throughput and low latency make it ideal for various applications, including the military. However, military use of 5G requires certain modifications to meet security standards, particularly to defend against adversarial threats like jamming."

Jamming occurs when an adversary sends a disruptive signal to interfere with communication channels, making it difficult for a receiver to decode the intended message. While this threat is not normally a concern for commercial 5G users, it is a major risk in military settings, where communication must be maintained even in hostile environments.

The research team focused on developing anti-jamming strategies to ensure military communications networks could withstand such attacks. Hossain likened this issue to bad actors compromising a secure office building (say, a headquarters) by infiltrating a less-protected satellite office. In military applications, particularly those involving unmanned vehicles or robots, compromising such resource-constrained devices could result in the loss of critical information at headquarters or even control over sensitive devices.

As the military continues to integrate emerging technologies like 5G into its operations, safeguarding these networks from adversarial threats becomes increasingly important. The collaboration between George Mason, UMD, and ARL demonstrates the critical role academic research plays in fortifying national security.

At MILCOM, the team’s work will be shared with a wider audience of defense and communication experts, contributing to the ongoing efforts to secure military networks in a connected world.
