Abstract:


Recent advances in electronic and computer technologies have paved the way for

the
proliferation of wireless sensor networks (WSN). Sensor networks usually

consist of a large
number of ultra
-
small autonomous devices. Each device,

called a sensor node, is battery
powered and equipped with integrated sensors,

data processing capabiliti
es, and short
-
range
radio communications. Sensor

networks are being deployed for a wide variety of
applications, including

military sensing and tracking, environment monitoring, patient
monitoring and

tracking, and smart environments.


When sensor networks

are deployed in hostile environments, security becomes

extremely
important. However, the cost

of achieving security might be
expensive for the energy
-
constrained sensors; reducing the costs in both computation and communication is very
critical. In this t
alk, I will first describe some major differences

between sensor network
security and traditional network security. I will then

present my recent work on how to take
advantage of sensor deployment knowledge to achieve security more efficiently. My talk wil
l
focus on secure location discovery and public key authentication.



Short bio:


Dr. Wenliang (Kevin) Du is an Assistant Professor

in the Department of Electrical
Engineering and Computer Science

at Syracuse University. He got his Bachelor's Degree
from t
he University of Science and Technology of China in 1993 and his Ph.D
.

degree from
Purdue

University in 2001.

His research focuses on three areas: sensor
-
network security,
privacy
-
preserving data mining, and using instructional operating systems

for comput
er and
network security education.
