Abstract

5G is assuringofan era of massive and ubiquitous connectivity. The 5G standard introduced enhancements towards security and scalability. Yet, the current state is far from meeting the security and robustness needs of the Department of Defense or DoD deployment, and lightweight scalability and extensibility needs of both DoD and civilian applications. From a practical perspective, there is a lack of clean-slate 5G software implementations that are flexible and designed for high security, robustness, and scalability. Many initiatives in DoD and academic research, and for accelerating connectivity,are hindered by the lack of maturity of existing open-source platforms, which have significant amounts of legacy code. The proposed Lightweight Scalable and Secure 5G and Beyond Networks project intends to iteratively develop a clean-slate forward-looking 5G and beyond dual use base that can be instantiated to meet the security and robustness needs of the DoD while providing the flexibility to support deployments with high societal impacts such as disaster recovery, anti-censorship, and bringing connectivity to under-served areas. This approach leverages recent results by the team on 5G security (e.g., ONR funded ROSETA project RObust and SEcure TActical 5G project). A first step consists of developing a lightweight minimal and extensible gNodeB base that can be deployed on low-power/cost platforms (including unmanned aerial vehicles and small-compute platforms) and enabling user equipment and user equipment sidelinks for DoD devices or disaster recovery use case. This base is extensible along multiple dimensions to gradually integrate defense mechanisms, outcomes of the research activities of the team. These techniques aim at spectrum and signaling integrity awareness; avoidance; stealth; and leveraging trusted execution environments towards zero trust. The proposed activities draw from the team’s multidisciplinary expertise spanning applied cryptography, network security protocols design, systems security, wireless communications, and RF machine learning systems.
