Dear Anna

I am not sure I can attend tomorrow (Dr. appointment.)  Any chance to get
the email address of this speaker as I have some mutual interest.

Networked Systems Distinguished Speakers Series presents: 

Improved Communications Protocols for Better Wireless Privacy

 

Speaker:        David Wetherall, associate professor of computer science and
engineering, University of Washington; Director, Intel Research, Seattle 

 

Time:           2-3 p.m.   

 

Date:           Thursday, Jan. 10, 2008

 

Location:       Calit2 Building, Room 3008

 

Abstract:       Wetherall and his group have started a new research effort
to build wireless systems that provide a high degree of privacy for the
users of mobile devices. Existing wireless protocols such as 802.11 transmit
unique identifiers, for example, MAC addresses that allow users to be
tracked and profiled by any nearby observer. This is becoming problematic as
wireless devices become more ubiquitous and more personal (with the
proliferation of mobile phones, personal fitness and medical devices,
headsets, and consumer electronics) and security problems become more
pressing (with the rise in identity theft and unintended disclosures). To
counter these threats, they are developing techniques that selectively
disclose addresses and other distinguishing information that maps to
high-level identities. 

 

This is challenging because addresses play a basic role in protocols such
that they cannot be concealed without impact; traditional encryption methods
such as WPA2, IPSEC and SSL do not prevent tracking and profiling. Wetherall
will discuss the problem of wireless privacy despite the best security
practices in use today, and give an overview of his link-layer protocol that
provides a high degree of privacy.

 

Bio:            Wetherall is an associate professor in the Department of
Computer Science and Engineering at the University of Washington, and
Director of the nearby Intel Research lab in Seattle. The lab is focused on
ubiquitous computing, computing systems that are woven into the fabric of
everyday life.  Wetherall joined the University of Washington faculty in
1999 after receiving his Ph.D, E.E. and S.M. in computer science from MIT;
he received his B.E. in electrical engineering from the University of
Western Australia in 1989. His thesis research pioneered active networks, an
architecture in which new network services can be introduced rapidly using
mobile code, and for which he received the SIGCOMM Test-of-Time Award in
2007. His research interests are concentrated in networking, including
wireless networks and the Internet. Wetherall received an NSF CAREER award
in 2002 and became a Sloan Fellow in 2004. His work on Internet mapping
received the Best Student Paper award at SIGCOMM 2002 and the IEEE Bennett
Prize in 2004.

 

Additional Information:    Refreshments will be served at 1:45 p.m. For more
