Abstract: Wireless networks play a key role in our business and
personal lives, but make the network vulnerable to attack from a
comfortable distance.  Attackers circumvent security protocols such as
WEP and WPA with impunity, allowing them to break into the network and
resulting in disastrous consequences for organisations.  The result is
an ongoing competition between new exploits and better wireless
security protocols.  To fundamentally change this status quo, we
propose SecureAngle, an approach to wireless security designed to
operate alongside and strengthen existing wireless security protocols.
SecureAngle uses cutting-edge multiple antenna signal processing to
profile the directions at which a client's signal arrives at the
access point and thereby construct signatures that uniquely
characterise each client.  In this talk, I will explore some potential
uses of SecureAngle's signatures: virtual fences, to disallow wireless
connections from outside a building or conference hall; address
spoofing protection, to prevent malicious clients from masquerading as
trusted clients; and a number of more speculative future applications.


Kyle Jamieson is a Lecturer in Networks at University College London.
He received the Ph.D. in June 2008 from the Massachusetts Institute of
Technology in Cambridge, Massachusetts.  His research interests are in
building real-world wireless systems that cut across the boundary of
digital communications and networking.
