Title: Memory Security Management for Embedded Systems Speaker: Russell Tessier, Department of Electrical and Computer Engineering, University of Massachusetts Abstract: The constrained operating environments of many FPGA-based embedded systems require flexible security that can be configured to minimize the impact on FPGA area and power consumption. In this presentation, a security approach for external memory in FPGA-based embedded systems that exploits FPGA configurability will be presented. Our FPGA-based security core provides both confidentiality and integrity for data stored externally to an FPGA which is accessed by a processor on the FPGA chip. The benefits of our security core are demonstrated using four embedded applications implemented on a
Stratix II device. Each application requires a collection of tasks with
varying memory
security requirements. Our security core is used in conjunction with a NIOS II soft processor running the MicroC/OS II operating system. An average memory and energy savings of about 64% and 16%, respectively, is achieved for the four applications versus a non-configurable, uniform security approach. In order to provide a secure end-to-end solution, a secure boot up mechanism and software update will also be detailed. This research is joint work with Romain Vaslin, Guy
Gogniat, and Jean-Philippe Diguet at the University of South Brittany
and Kris Gaj
at George Mason University. Bio: Russell Tessier is an associate professor of electrical and computer engineering at the University of Massachusetts, Amherst. He received the B.S. degree in computer engineering from Rensselaer
Polytechnic Institute, Troy, NY in 1989 and S.M. and Ph.D. degrees in
electrical engineering
from MIT, Cambridge, MA in 1992 and 1999,
respectively. Dr. Tessier was a founder of Virtual Machine Works, a
logic emulation company, and
has also worked at BBN, Ikos Systems, and Altera.
Prof. Tessier currently leads the Reconfigurable Computing Group at
UMass. His research
interests include computer architecture, field-programmable gate arrays, and embedded system design. |
