Super-linear Scaling Behavior for Electric Vehicle Chargers and Road Map to Addressing the Infrastructure Gap

Abstract: Enabling widespread electric vehicle (EV) adoption requires substantial build-out of charging infrastructure in the coming decade. We formulate the charging infrastructure needs as a scaling analysis problem and use it to estimate the EV infrastructure needs of the US at a county-level resolution. Surprisingly, we find that the current EV infrastructure deployment scales super-linearly with population, deviating from the sub-linear scaling of gasoline stations and other infrastructure. We discuss how this demonstrates the infancy of EV station abundance compared to other mature transportation infrastructures. By considering the power delivery of existing gasoline stations, and appropriate EV efficiencies, we estimate the EV infrastructure gap at the county level, providing a road map for future EV infrastructure expansion. Our reliance on scaling analysis allows us to make a unique forecast in this domain.

Towards A Secured SCADA Architecture: A DNP3 Test Case

Abstract: The foundation of a country's critical infrastructures (CI), which provide crucial services, is its security, healthcare, and economic systems. By lowering CI's operational costs and associated expenses and enhancing its effectiveness and safety, appropriately functional CI infrastructure plays an essential role in the prosperity of the nations. To do so, businesses that manage CIs frequently combine the Internet of Things (IoT) with Cyber-Physical Systems (CPS), such as SCADA systems. SCADA systems were not initially built with web security in mind, exposing CIs open to security risks. National security issues can arise when these technologies are connected to power plants and water treatment facilities. This study aims to demonstrate how security features can be implemented in DNP3-based SCADA infrastructures. By creating a functional configuration and consensus amongst the communicating devices, the DNP3 protocol will support digital signatures. The team proposed a SCADA architecture to accomplish this, making it possible for these systems more secure manner.

Detection of Cyber Attacks on a Water Distribution Testbed

Abstract: The increasingly networking of sensors and actuators in critical infrastructures improves the flexibility, but also raises security challenges. This paper presents a strategy to detect cyber attacks on a kind of critical infrastructure, namely water distribution systems. The real operation data from the Water Distribution (WADI) testbed, a scale-down water distribution system developed by the iTrust Center for Research in Cyber Security at the Singapore University of Technology and Design, is utilized in this study. The proposed attack detection system consists of a limit value unit, a rule-based unit, and an observer-based monitoring unit. Finally, the proposed detection system is compared with other existing approaches for the WADI process in the literature, which shows the advantage of the proposed system.
