To lower costs and improve outcomes in current medical practice we need integrated interoperable medical systems to provide machine-assisted care, interaction detection, and improved alarm accuracy, to name just a few uses. This project is developing both the theory and practice to ensure the safety of next-generation medical devices by allowing secure coordination and composition, in facilities as small as a local doctor's office or as large as a multi-campus hospital.

Silicon physically unclonable function (PUF) is a supplemental circuit embedded in an IC which generates signatures unique to its native IC. This signature could be used for authentication, protection of data and secure communication. PUFs rely on the presence of uncontrollable variations in the fabrication process causing the circuit parameters to exhibit randomness. Current approaches for PUF design have mostly investigated circuit and architectural aspects. PUF quality is severely marred by a lack of understanding of exactly how fabrication process variations impact the PUF responses.

Computers and people live in a world governed by policy. At the lowest level, policies determine how information flows within networks; at the highest level, they describe how users' personal information is shared across applications. Of course, end-users, as policy authors, make mistakes: rules can have unintended consequences and multiple policies can interact in ways that their authors didn't intend. Users can benefit from tools to help them understand the policies they write and maintain. Policy analysis refers to rigorous methods for detecting these situations before they cause harm.

The "Virtual Laboratory and Curriculum Development for Secure Mobile Computing" project at the University of Texas at Dallas (UTD) will develop a set of courses and a virtual laboratory in mobile system security with an emphasis on securing smart phones. The courses that will be developed will include topics such as Android taint analysis using existing tools or development of new tools, scalable Android security threat analysis on applications (apps), and smart phone forensics.

Malware (e.g., viruses, worms, and Trojans) is software that deliberately fulfills the harmful intent of an attacker. It has been used as a major weapon by the cyber-criminals to launch a wide range of attacks that cause serious damages and significant financial losses to many Internet users. To protect legitimate users from these attacks, the most significant line of defense against malware is anti-malware software products, which predominately use signature-based methods to recognize threats.
