Dr. Peter J. Hawrylak’s research encompasses the areas of RFID (radio frequency identification), security for low-power wireless devices, Internet of Things (IoT) applications, and digital design. His research focuses on developing energy harvesting solutions for battery-less sensors and actuators in small form factors and how to apply these technologies in a collaborative manner. Powering such devices in difficult scenarios, including in vivo, remote locations, or harsh operating conditions, over long periods of time is a multifaceted problem. Hawrylak’s approach is to employ a variety of energy harvesting means to power such devices, instead of relying on a battery to power the device, and thus enabling their use in these difficult operating conditions for long periods of time. Energy harvesting technologies investigated include photovoltaic (PV), radio frequency, thermal, and piezoelectric.

How to secure such a systems is an open question because these types of systems do not have the computational capabilities to support traditional security features. The limited security resources introduce several new attack vectors, including the “Energy Draining Attack” where the goal is not to compromise the system through traditional means, but to simply drain its operating energy so it cannot function, in effect a “denial of device attack”.
