Security & Privacy Protection in IoT MGC Systems


Prof. Robert Deng
AXA Chair Professor of Cybersecurity
Singapore Management University

Abstract: Many IoT and cyber-physical systems follow the MGC (eMbedded-Gateway-Cloud) architecture. In this architecture, embedded devices equipped with sensors send measurement data to a gateway which aggregates the data into appropriate records and upload them to the cloud for data access and analytics. An example application of the MGC architecture is infrastructure video monitoring, in which drones and robots with mounted cameras patrol physical operational environments for on-site monitoring, defeats inspection, etc, and videos are encrypted at a gateway and then uploaded to cloud for authorized access by various stake holders. In this talk, we will discuss the various data security and privacy issues in the infrastructure video monitoring system (and MGC architecture in general) and present a data security and privacy platform which supports flexible access control of encrypted data based on users’ attributes and time of access and supports multiuser-to-multiuser encrypted keyword search over encrypted data.
Speaker’s Bio: Robert Deng is AXA Chair Professor of Cybersecurity, Director of Secure Mobile Centre, and Deputy Dean for Faculty & Research, School of Computing and Information Systems, Singapore Management University (SMU). His research interests are in the areas of data security and privacy, network security, and applied cryptography. He received the Outstanding University Researcher Award from National University of Singapore, Lee Kuan Yew Fellowship for Research Excellence from SMU, and Asia-Pacific Information Security Leadership Achievements Community Service Star from International Information Systems Security Certification Consortium. He is a Fellow of IEEE and Fellow of Academy of Engineering Singapore.

Digital twins: Double Insecurity for Industrial Scenarios


Prof. Cristina Alacaraz
Associate Professor
University of Malaga

Abstract: Industry 5.0 is increasingly having a greater influence on the modernization of industrial processes in order to improve not only its own value chain but also the supply chain within a context. In this case, Digital twins (DTs) is a leading technology, providing simulation capabilities to analyze, predict and optimize possible scenarios and situations, which is encouraging different industrial actors to invest in the technology, and especially to intensify the three Industry 5.0 objectives: centrality in the human being, sustainability and resilience. But this fact, in turn, forces the scientific community to pay attention to the risks that may be involved in adapting the technology itself in its operational domains. The deployment of a DT involves a set of risks and threats that are a consequence of its own criticality, what affects seriously Industry 5.0 resilience. In this talk, therefore, we will talk about that particular context of a DT, where we will explore potential threats that can corrupt the objectives of Industry 5.0, adding some security recommendations that can benefit, at least, the expected Industry 5.0 resilience.
Speaker’s Bio: Cristina Alcaraz is an Associate Professor in the Computer Science Department at UMA. She has been awarded two competitive postdoctoral fellowships: Marie-Curie in 2012 and Ramon-y-Cajal in 2015 and was a guest researcher at NIST (2011-2012), visiting later the Royal Holloway (2012-2014, under the Marie-Curie fellowship), UCBM (2017, Rome) and the University of Piraeus (2019 and 2022, Athens). She is interested in the security of cyber-physical systems, Industry 4.0/5.0, smart grids, IIoT and digital twins, focusing the research on situational awareness, advanced detection and resilience. She has published 75+ papers, is a member of the editorial boards of 8+ international journals in the area (e.g., IEEE Transactions on Industrial Informatics, IEEE Transactions on Dependable and Secure Computing, ACM Distributed Ledger Technologies, IEEE Networking Letters, IJCIP, IJIS, among others), received the Women in Homeland Security Award by the IEEE SMC TC on Homeland Security in 2021 and she is the Vice-Chair of IEEE ComSoc SIG on Green Digital Twin Network.
