CESCA Research Day presentation and audience
March 2013. CESCA hosted its first “CESCA Research Day”, research symposium on Embedded Security at the Virginia Tech Research Center in Arlington on March 15, 2013. Approximately 25 designers and managers from industry, government organizations, academia, and research labs attended the full-day symposium to learn about leading-edge research and development related to secure and embedded systems and to network with faculty, students and other professionals who have similar interests.
CESCA Director Patrick Schaumont welcomed the attendees, followed by Charles Clancy, associate professor and director of the Hume Center, who talked about research directions in security. Three morning research sessions covered the topics of secure design, applications, and secure design methods. Brief overview of the research work was presented by all 7 CESCA faculty members: Professor Michael Hsiao; Associate Professors Lynn Abbott, Leyla Nazhandali, Patrick Schaumont, Jerry Park, and Yaling Yang; and Assistant Professor Chao Wang. Between the research sessions, 8 Ph.D. students from CESCA (Aydin Aysu, Avinash Desai, Zhenhe Pan, Sarvesh Prabhu, Meeta Srivastav, Ting Wang, Lu Zhang) presented their work through poster and demonstration sessions.
After lunch, attending companies introduced themselves to the students for internship and employment opportunities. Because all sessions were also simulcast to Blacksburg, CESCA students in Blacksburg were able to follow those presentations. Participants were then offered 4 parallel tutorial sessions from which to choose: Introduction to Side Channel Analysis; Software Testing and Verification; Physically Unclonable Functions; and Wireless Security.
The website of the Research Day hosts videos as well as slides of the presentations. With this outreach event, CESCA has forged valuable relationships with the participants. CESCA is especially interested into attracting partners to its Industry Affiliate Program, and encourages companies with a stake in critical embedded systems design to contact us.

NEMS eyed for CMOS Power Gating (project by Leyla Nazhandali)
Novel Microprocessor-based Physical Unclonable Function Demonstrated (project by Patrick Shaumont)
October 2012. Director of CESCA Dr. Patrick Schaumont and former CESCA faculty Dr. Sandeep Shukla will teach new graduate-level courses in Spring 2013.
ECE 5984: Handheld Computer Security by Schaumont
5984 Syllabus Spring 2013 (PDF | 15KB)
ECE 5984: Model-driven design of embedded software by Shukla
"Students will learn an emerging methodology for incorporating synchronous, polychronous, and other formal models into the embedded system design process (cited from "ECE News")
October 2012. The steady rise in leakage power over the last decade has made low-power design an exceedingly difficult problem mainly because attempts to control leakage power tend to negatively impact performance and switching energy. The industry standard approach for power gating with on-die transistors has major drawbacks including residual off-state leakage, which still forces designers to resort to leakage control measures such as high threshold voltages. Dr. Leyla Nazhandali, a faculty member of CESCA and Secure and Power Aware Computing (SePAC) lab, is set to solve this dilemma with Masoud Agah (director of VTMEMS Lab) by using Nanoelectromechanical Systems (NEMS) switches. Their recent NSF-funded project intends to thoroughly investigate all aspects of CMOS-NEMS integration. The final product is a fabricated CMOS-NEMS hybrid that would allow us to conclusively determine the effectiveness of NEMS-based power gating.
August 2012. CESCA Faculty members Dr. Yaling Yang and Dr. Chao Wang with Co-PI Jeff Reed have recently won a $700,000 multiyear National Science Foundation (NSF) award. The project, titled “SDR Shield: A Hardware-based Security Solution for Software Defined Radio”, aims at designing an effective hardware-based SDR integrity assessment and behavior regulation device named SDR Shield.
August 2012. The Secure Embedded Systems (SES) lab in CESCA has demonstrated a novel Physical Unclonable Function (PUF), implemented in a microprocessor. An on-chip PUF is an integrated structure that creates a chip-unique response. It can be used to uniquely distinguish one single chip among a large population of identical chips. PUFs are used for cryptographic key generation, and for authentication. Most of the existing PUF designs, however, consume a high amount of silicon resources and/or energy. This makes them less useful for embedded implementations.
Using overclocking techniques, Abhranil Maiti (PhD student at SES) was able to demonstrate the uniqueness of a single microprocessor chip by observing its failure points due to the overclocking. The advantage of the technique, which is non-destructive, is that it is driven using software, and that it makes use of an existing microprocessor. The technique was demonstrated on a LEON-3 processor configured in Xilinx Spartan FPGA, but it is generally applicable to other microprocessors for which clock scaling is available. The novel PUF will be presented at the 2012 International Conference on Field Programmable Logic and Applications.
July 2012. Michael Henry graduated in December 2011 with a Ph.D in Computer Engineering (advisor: Leyla Nazhandali) and started an engineering R&D company. He currently has Phase 1 Small Business Innovation Research (SBIR) funding from the Air Force to design and eventually prototype a low-power military-capable GPS receiver. This project involves collaboration with the VLSI Design/Automation lab at the University of Michigan, Ann Arbor and he is currently based in Ann Arbor. In addition to working towards Phase 2 funding on the Air Force contract, he is also applying for other SBIR contracts relating to advanced wide-spectrum CMOS image sensors and neuromorphic image processing.

"Self-charging structures" wins the best paper prize at SMASIS 2009
September 2009. Three CIMSS (Center for Intelligent Material Systems and Structures) members (Daniel Inman and his students Anton, and Erturk) and two CESCA members (Dong Ha and his student Na Kong) developed a self-charging structure, which won the best paper award at the ASME Conference on Smart Materials, Adaptive Structures and Intelligent Systems (SMASIS) in September 2009. The structure provides multifunctionality capabilities in a single device that can harvest vibration energy, stored harvested energy, and bear the load. The 'self-charging structures' are multilayered, composite devices consisting of active piezoceramic layers for scavenging energy, flexible thin-film battery layers for storing scavenged energy, and a central metallic substrate layer. A key advantage of the self-charging structure design is that, unlike traditional vibration energy harvesting devices that are designed as add-on components to a host system, self-charging structures can be integrated into a system to provide load bearing capacity and eliminate the mass loading effects found in conventional designs.Ha is awarded with a US patent in digital DC/DC converter design.

April 2009. Virginia Tech has been one of Pratt & Whitney Centers of Excellence, and Dong Ha has received a research project from Pratt & Whitney through the Center. The project aims to develop a sensor node for monitoring and testing of aircraft engines. The work involves development of network protocols, incorporation of high speed wireless radios and fiber optic communication devices, and implementation of sensor interfaces. Dong Ha's team will collaborate closely with other ME (Mechanical Engineering) teams of the Center and will test the sensor node with a real aircraft engine. The amount of funding for the project is $156K for two years.
Ha Collaborates in Energy Harvesting Research with CIMSS
February 2009. Virginia Tech’s Center for Intelligent Material Systems and Structures (CIMSS) directed by Prof. Dan Inman has teamed with Physical Acoustics Corporation (PAC), of Princeton Junction, NJ, to develop a suite of new technologies to provide a continuous, energy independent monitoring of the structural integrity of U.S. bridges. The National Institute of Standards and Technology (NIST) funds $14M for five years for the research, with Virginia Tech’s share at about $2M. The research with Virginia Tech includes development of an innovative method for “harvesting” power from motions and vibrations in a bridge using piezoelectric materials, and Dong Ha’s team is responsible for design of power conditioning circuits.
Two CESCA Faculty Members Were Featured in Virginia Tech Annual Report 2007- 08
December 2008. Improving the security of cognitive radio technology is the goal of Virginia Tech College of Engineering researcher Jung-Min Park. Park, an assistant professor in the Bradley Department of Electrical and Computer Engineering, said that cognitive radio technology will be used for two-way communications in a wide range of applications, such as communication systems for tactical military forces and emergency responders. It also might be used in the development of wireless access networks that can provide Internet services to rural areas.
