Abstract
The rapid growth of Internetworking has led to a flood of applications that can benefit from network-connectivity. Unfortunately, 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 applications. First, I will describe a bottom-up, principled approach to securing wireless ad hoc network routing; unlike previous work, which examines specific attacks and defenses, our approach provides guarantees a specific asymptotic performance level regardless of attack. Next, I will describe a novel approach to Internet Denial-of-Service, where we use a router's existing traffic filtering functionality to implement a capability-like system, giving a destination end-host the ability to control inbound traffic with minimal modifications to existing network infrastructure. Finally, I will describe my first steps in the area of security for health applications. In this work, my group demonstrated physiological limitations to the body-wide sensing of body physiological values, in particular the Electrocardiograph (ECG) signal. We then proposed an alternative scheme, where an artificial low-level voltage signal can be injected onto the body and used for same-body authentication at a very low bit rate.
Biography
Yih-Chun Hu is an Associate Professor with the Department of Electrical and Computer Engineering, University of Illinois at Urbana-Champaign, Urbana. His research interests are in security in networked systems, with particular interest in the areas of wireless, cyberphysical systems, and medical systems. He received the B.S. degree in computer science and pure mathematics 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-Doctoral Researcher with the University of California, Berkeley.
