Authentication and integrity are foundational security services for trustworthy systems and the prerequisite of privacy preservation. At the heart of these services lies digital signatures, widely deployed in real-life applications and supported by various standards. Yet, newly emerging next-generation (NextG) networked systems are vastly distributed, include many resource-limited components, and demand advanced features such as privacy, anonymity, and post-quantum (PQ) security. However, the current signature standards and specialized signatures only meet some of these important requirements in isolation. Hence, there is a significant gap in the state-of-theart in identifying the needs of emerging networked systems and synergizing them with the features of advanced signatures. In this work, we strive to mitigate this gap by uniting burgeoning ubiquitous systems with advancements in digital signatures and then envisioning the trust via signatures with extended features for NextG networked systems. We investigate the current signature standardizations and advanced constructions for their potentials and drawbacks in three essential aspects of NextG networks - decentralized, privacy-preserving, and resource-constraint settings. We first analyze threshold cryptography efforts proffered by NIST, both from secure multi-party computation and custom design constructions, with applications on distributed systems like blockchains, federated cloud, and NextG Public Key Infrastructures (PKIs) in mind. We then investigate the intersections of distributed signatures and privacy-preservation techniques for privacy-sensitive NextG applications (e.g., medical, cryptocurrency). We also focus on research gaps for resource and time-limited systems and identify suitable signatures to remedy this gap for security-critical applications (e.g., vehicular networks, smart grids). Finally, we discuss potential directions for these ubiquitous NextG systems and advanced signatures in the PQ era.

Multi-human parsing algorithms have significant potential for real-time surveillance applications. By accurately segmenting humans and their body parts, such algorithms help to understand and better differentiate multiple human subjects in video frames. However, deploying such algorithms on resource-constrained embedded devices such as smart cameras presents challenges due to memory constraints and limited computational power. Therefore, this work investigates the limitations of existing multi-human parsing algorithms and proposes MHParsNet, a lightweight yet accurate model for human parsing on embedded devices. Compared to benchmark algorithms, MHParsNet performs competitive segmentation while requiring only 125 MB of memory. We deployed MHParsNet on a smart camera prototype using the Jetson Nano embedded board and achieved an average inference of 6 frames per second. These results demonstrate the effectiveness of MHParsNet and its suitability for real-timeapplications on resource-constrained embedded devices.

Digital twins (DTs) represent a transformative paradigm in urban management, leveraging computer modelling and real-time data integration to create virtual replicas of physical entities and systems. This paper explores their multifaceted applications, emphasizing efficiency, sustainability, and resilience. Synthesizing insights from diverse disciplines, it delineates the process of building digital twins and underscores their role in predictive maintenance, optimized performance, and data-driven decision-making. Using a smart city example, the paper illustrates how digital twins facilitate proactive interventions, resource optimization, and informed decision-making in domains such as traffic management, energy optimization, and public safety. It highlights the significance of digital twins in fostering collaboration, innovation, and resilience, empowering cities to address complex challenges and create inclusive, sustainable environments. In conclusion, digital twins emerge as indispensable tools in realizing the vision of smart, connected, and adaptive cities, poised to navigate the complexities of the contemporary urban landscape and pave the way for a sustainable future.

We address the challenges in achieving optimal Quality of Information (QoI) for non-dedicated vehicular Mobile Crowdsensing (MCS) systems, by utilizing vehicles not originally designed for sensing purposes to provide real-time data while moving around the city. These challenges include the coupled sensing coverage and sensing reliability, as well as the uncertainty and time-varying vehicle status. To tackle these issues, we propose QUEST, a QUality-informed multi-agEnt diSpaTching system, that ensures high sensing coverage and sensing reliability in non-dedicated vehicular MCS. QUEST optimizes QoI by introducing a novel metric called ASQ (aggregated sensing quality), which considers both sensing coverage and sensing reliability jointly. Additionally, we design a mutual-aided truth discovery dispatching method to estimate sensing reliability and improve ASQ under uncertain vehicle statuses. real-world data from our deployed MCS system in a metropolis is used for evaluation, demonstrating that QUEST achieves up to 26% higher ASQ improvement, leading to a reduction of reconstruction map errors by 32-65% for different reconstruction algorithms.
