RINGS: Resilient Edge Ecosystem for Collaborative and Trustworthy Disaster Response (REsCue)

点击翻译按钮获取中文摘要

This project addresses networking and security challenges in next generation public safety and disaster response networks, where mission-critical emergency operations (e.g., search and rescue) need to be performed with limited surviving infrastructure, potentially augmented with diverse devices deployed by first responders. These mission-critical operations are performed in a challenging environment and can only be effective if the fundamental security and architectural challenges specific to them are addressed, which is the goal of this project. The project's novelties are: (i) effective integration of diverse autonomous networks (e.g., utilities and smart homes) into a resilient, cooperative, and secure network-of-networks; (ii) a system for supporting network operations during broad disruptions including the enforcement of access control to data and services, and (iii) efficient verification of untrusted users' communications. The project's broader significance and importance are two-fold: (i) providing new research outcomes in networking, near-user computing, low-latency wireless communications, and cybersecurity, leading to the creation of disruption-tolerant networks, whose use extends beyond effective disaster/emergency response to other applications, such as rural networking and distributed manufacturing; and (ii) contributions to a diverse workforce through recruitment and training of a diverse student population. The project identifies the fundamental architectural and security challenges in fragmented networks, such as seamless multi-modal communications, resilient and verifiable computing, and trust management, and addresses them for viable deployment in disaster-response scenarios. The resulting outcome is a generic blueprint to design an edge-centric, trustworthy, and resilient named data networking architecture. The project also investigates foundational resilience challenges including engendering trust without a centralized certificate authority in a network stitched-together from independent network fragments, providing flexible and revocable access control and authorization for data/services, and ultra-reliable low latency wireless communications in challenging environments. The proposed designs and solutions, grounded in rigorous analytical frameworks and theoretical models, reinforced by real-world experimental evaluations, will form the basis for future edge network innovations.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
