In many multi-user cryptographic applications (e.g., electronic voting, digital lotteries, e-cash application, anonymous access to some resources, etc.), anonymity pops up as one of the main security objectives. Protecting private...
In this dissertation we study the security and survivability of wireless mobile network systems in two distinct threat models: the Byzantine threat model and the sel¯sh node threat model. Wireless mobile networks are collections of self...
Adversarial yet interacting interdependent relationships in information sharing and service provisioning have been a pressing issue of the Internet. Such relationships exist among autonomous software agents, in networking system peers, ...
Routing in mobile ad hoc networks presents many challenging problems not faced when routing in static networks with infrastructure. While much research has been done in this area, there is still much progress left to make before routing...
This thesis develops and studies a traffic-aware inter-domain routing (TIDR) protocol, which drastically improves the convergence and stability of the BGP-based inter-domain routing system. TIDR is designed based on two important...
At its heart, a password cracking attack is just a guessing attack. An attacker makes guesses about a user's password until they guess correctly or they give up. While the defender may limit the number of guesses an attacker is allowed, ...
Mobile ad hoc networks, or MANETs, are wireless networks that do not depend on a fixed infrastructure. The wide array of uses for ad hoc networks creates many different levels of security requirements. This work begins by exploring...
Mobile Ad Hoc Networks (MANETs) are a collection of wireless mobile nodes with links that are made and broken arbitrarily. They have limited resources in power, computation, broadcast range, and a dynamic topology with no fixed...
