Cyber-Physical Systems (CPS)

Control-related attacks are a severe threat to cyber-physical systems (CPSs) such as smart grids, because they can introduce catastrophic physical damage by using malicious control commands crafted in a legitimate format. While current research efforts have focused on detecting malicious commands that lead to physical damage, the investigator proposes to preemptively prevent the damage by disrupting and misleading adversaries' preparation before they issue the malicious commands.

Increasingly medical devices are dependent on software and the wireless channel for their operations, which also pose new vulnerabilities to their safe, dependable, and trustworthy operations. Medical devices such as implantable insulin pumps, which are in wide use today, continuously monitor and manage a patient's diabetes without the need for frequent daily patient interventions. These devices, not originally designed against cyber security threats, must now mitigate these threats.

This project provides support for a National Academies Roundtable, the Forum on Cyber Resilience. The Forum will facilitate and enhance the exchange of ideas among scientists, practitioners, and policy makers concerned with the resilience of computing and communications systems, including the Internet, critical infrastructure, and other societally important systems.

The modernized electric grid, the Smart Grid, integrates two-way communication technologies across power generation, transmission and distribution, in order to deliver electricity efficiently, securely and cost-effectively. On the monitoring and control side, it employs real-time monitoring offered by a messaging-based advanced metering infrastructure (AMI), which ensures the grid?s stability and reliability, as well as the efficient implementation of demand response schemes to mitigate bursts demand.

The design of smart electric grids and buildings that automatically optimize their energy generation and consumption is critical to advancing important societal goals, including increasing energy-efficiency, improving the grid's reliability, and gaining energy independence. To enable such optimizations, smart grids and buildings increasingly rely on Internet-connected sensors in smart devices, including digital electric meters, web-enabled appliances and lighting, programmable outlets and switches, and intelligent HVAC systems.
