DESCRIPTION:Yih-Chun Hu\, University of Illinois at Urbana-Champaign\nIC f
 aculty candidate\nAbstract\nThe rapid growth of Internetworking has led to
  a flood of applications that can benefit from network-connectivity. Unfor
 tunately\, when the network and many such applications were first designed
 \, they were designed without security in mind. In this talk\, I describe 
 three areas in my research to bring security to both networks and applicat
 ions. First\, I will describe a bottom-up\, principled approach to securin
 g wireless ad hoc network routing\; unlike previous work\, which examines 
 specific attacks and defenses\, our approach provides guarantees a specifi
 c asymptotic performance level regardless of attack. Next\, I will describ
 e a novel approach to Internet Denial-of-Service\, where we use a router's
  existing traffic filtering functionality to implement a capability-like s
 ystem\, giving a destination end-host the ability to control inbound traff
 ic with minimal modifications to existing network infrastructure. Finally\
 , I will describe my first steps in the area of security for health applic
 ations. In this work\, my group demonstrated physiological limitations to 
 the body-wide sensing of body physiological values\, in particular the Ele
 ctrocardiograph (ECG) signal. We then proposed an alternative scheme\, whe
 re an artificial low-level voltage signal can be injected onto the body an
 d used for same-body authentication at a very low bit rate.Biography\nYih-
 Chun Hu is an Associate Professor with the Department of Electrical and Co
 mputer Engineering\, University of Illinois at Urbana-Champaign\, Urbana. 
 His research interests are in security in networked systems\, with particu
 lar interest in the areas of wireless\, cyberphysical systems\, and medica
 l systems. He received the B.S. degree in computer science and pure mathem
 atics from the University of Washington\, Seattle\, in 1997\, and the Ph.D
 . degree in computer science from Carnegie Mellon University\, Pittsburgh\
 , PA\, in 2003. After receiving his Ph.D. degree\, he worked as a Post-Doc
 toral Researcher with the University of California\, Berkeley.
