Visible to the public Foundations of Secure Cyber-Physical Systems of Systems

Factories, chemical plants, automobiles, and aircraft have come to be described today as cyber-physical systems of systems--distinct systems connected to form a larger and more complex system. For many such systems, correct operation is critical to safety, making their security of paramount importance. Unfortunately, because of their heterogeneous nature and special purpose, it is very difficult to determine whether a malicious attacker can make them behave in a manner that causes harm. This type of security analysis is an essential step in building and certifying secure systems.


Visible to the public Architecturally-Integrated Hazard Analyses for Medical Application Platforms

The objective of this research is to develop new forms of tool-supported safety analyses for next-generation integrated medical systems that are based on the concept of medical application platforms (MAP). A MAP is a safety- and security-critical real-time computing platform for (a) integrating heterogeneous devices, medical IT systems, and information displays via a communication infrastructure and (b) hosting application programs ("apps") that provide medical utility via the ability to both acquire information from and update/control integrated devices, IT systems, and displays.
