ABSTRACT

Networks are increasingly used for critical functions, such as e-commerce and online banking. Unfortunately, networking services were designed for trusted environments, and are consequently extremely vulnerable to attack.

In this talk, I will describe my work on securing routing, the central network service, in both wireless ad hoc networks and in the Internet. In the context of securing wireless ad hoc network routing, I then describe my work on SEAD, a simple and highly efficient protocol that secures the distance vector protocol against attack. I then present SPV, my protocol for secure Internet routing. This protocol is the first that provides strong security properties even when relatively few ISPs deploy the protocol, and even when those ISPs are not directly connected. Furthermore, SPV is highly efficient in computation.

BIOGRAPHY

Yih-Chun Hu received his B.S. from the University of Washington in 1997 and his Ph.D. from Carnegie Mellon University in 2003. In his thesis work at Carnegie Mellon, he focused on security and performance in wireless ad hoc networks. Yih-Chun's research interests include security and systems. He is currently a visiting postdoctoral researcher at the University of California, Berkeley.
