GTID: A Technique for Physical Device and Device Type Fingerprinting

Dr. A. Selcuk Uluagac
Georgia Institute of Technology

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.

Bio: 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). 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 security fields. 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. -- Speaker website:
