GTID: A Technique for Physical Device and Device Type
Wednesday, February 6, 2013 - 10:00am - 11:10am KEC 1007 Selcuk Uluagac Research Faculty School of Electrical and Computer Engineering Georgia Institute of Technology Abstract: In this talk, I will introduce GTID, a technique that passively fingerprints device and device types. This is accomplished by exploiting the heterogeneity of devices, which is a function of the different device hardware compositions and the innate variation in the chip fabrication process. GTID relies on the use of statistical analysis to measure time variant behavior in network traffic to create unique, reproducible device and device type signatures. This technique is applied to the challenging problem of access control in 802.11 networks. I will discuss the efficacy of GTID on both an isolated testbed and a live campus network. Further, I will show, using a corpus of 30 devices representing a wide range of device classes, that GTID has high accuracy and good recall in identifying previously seen and unknown devices and device types. Finally, I will present the efficacy of GTID under various attacker models and discuss its prototype implementation performance.Speaker Biography: Dr. A. Selcuk Uluagac is currently a member of the research faculty in the School of Electrical and Computer Engineering at Georgia Institute of Technology affiliated with Communications Systems Center (CSC), Communications Assurance and Performance (CAP) Group, and Georgia Tech Information Security Center (GTISC). Prior to joining the faculty at Georgia Tech, he was a Senior Research Engineer at Symantec. He earned his Ph.D. with a concentration in information security and networking from the School of Electrical and Computer Engineering, Georgia Institute of Technology in 2010. He also received an M.Sc. in Information Security from the School of Computer Science, Georgia Institute of Technology and an M.Sc. in Electrical and Computer Engineering from Carnegie Mellon University in 2009 and 2002, respectively. He received his B.S. degree in Computer Engineering from the Turkish Naval Academy in 1997. The focus of his research lies at the intersection of the networking and se!
curity fields. Of particular interest to Dr. Uluagac is designing secure and energy efficient communication protocols and architectures. In 2007, he received "2007 Outstanding ECE Graduate Teaching Assistant Award" from the School of ECE at Georgia Institute of Technology. He is a member of IEEE (senior grade), ACM, and ASEE.
