Securing Network Routing

Yih-Chun Hu

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.
