Title: Data Mining for Security of the Industrial Internet of Things
Description of the special session topic:
The Industrial Internet of Things (IIoT) brings the cyber and the physical worlds together. It provides huge advantages to improve the efficiency of industrial production and introduces major security challenges because of the extensive networking between internal industrial networks and external information networks. Further, such IIoT security may trigger serious accidents to endanger public safety, especially in high-risk domains such as nuclear, aircraft, chemical, oil and mining, automatic driving, and transportation industry. In these domains, a small misoperation can be catastrophic. Industrial security tries to reduce such threats by defending the attacks from cyberspace. With the aid of various sensors and learning-based components in the industrial equipment, and the data mining algorithms, we can produce a feasible scheme to ensure the security of IIoT from the source by mining the features of the potential risks. Hence, there is a need to study and design data mining for security for the IIoT.

Title of the presentation: Learning Based Privacy Protection in Internet of Things
Abstract: The rapid development of the Internet of Things (IoT) has given birth to the emergence of service models such as intelligent transportation, telemedicine, and location-based services. However, they face different privacy issues, such as eavesdropping attack and advance persistent threat, which has caused huge economic losses and even harm national security. Additionally, these new service models face challenges such as the complexity of the IoT environment, the unknown privacy leakage model, the limited resources of the IoT devices, and the time-sensitive requirements. In this talk, we introduce the privacy protection schemes in three typical scenarios of cloud storage systems, mobile edge computing, and location-based services for privacy leakage in the IoT. We apply game theory, reinforcement learning, and differential privacy to investigate intelligent privacy protection scheme. This work provides a theoretical basis and useful suggestions for the future design of the IoT privacy protection framework.

Title of the presentation: Cybersecurity in Microgrid
Abstract: A microgrid is a small-scale distribution grid, made up of electricity users with local renewable and other energy sources. The smart microgrid can make intelligent decisions to produce significant savings by lowering energy costs and by managing onsite energy usage to avoid peak energy prices while supporting grid stability and improving return on investment. However, when utility companies extend their proprietary substation industrial network to the Internet to cover the grids, they face more critical cyber threats than other industries. Our project is to build a smart microgrid system on campus, develop cybersecurity technologies, and offer cybersecurity validation services to local companies.

Title of the presentation: A Research on Device-free Human Activity Recognition using Physical Layer Information
Abstract: Passive human activity recognition is a hot research topic with important theoretical value and broad application prospect in the field of wireless intelligent sensing. At present, there are many achievements in passive human activity recognition domain using wireless signals, such as activity detection, activity recognition, attribute estimation and trajectory tracking of people.

Title of the presentation: Variational Inference Assisted Ground Truth Analysis for Data Management of IIoT
Abstract: The continuous expanded scale of the industrial Internet of Things (IIoT) leads to IIoT equipments generating massive amounts of uncertain user data every moment. How to make use of these uncertain data in an efficient and safe way in the field of IIoT is still an open issue, such that it has attracted extensive attention from academia and industry. As a new machine learning paradigm, variational inference (VI) has great advantages in obtaining the ground truth from uncertain data. This article studies the VI technology applications to manage IIoT equipment data in wireless network environments. Therefore, we propose a VI algorithm assisted ground truth analysis for data management of IIoT (VIIIoT), which can take into account the privacy and efficiency of data training of IIoT equipment. VIIIoT provides more general insights into the forming of user features, can be easily extended to higher dimensions and has the merits of low complexity, easy scaling and generality. Experiments show that VIIIoT outperforms the other existing type of machine learning algorithms, and it has higher accuracy in terms of mean absolute error (MAE) and root mean square error (RMSE).
