Trustworthy Overlay Peer-to-Peer Streaming Systems

Overview

With the proliferation of peer-to-peer systems, it is critical to consider how these systems can be deployed in a safe, secure and robust manner and understand their impact on an Internet environment already suffering from several security problems. Peer-to-peer systems provide increased scalability and enable rapid deployment by moving functionality from core routers to end-systems. However, as end-nodes are more likely to be compromised than core routers, peer-to-peer systems are vulnerable to malicious outsider attacks, as well as to insider attacks coming from (potentially colluding) attackers that infiltrate the overlay or compromise member nodes.

The main research focus of this project is to create novel, trustworthy overlay systems by identifying and addressing critical security aspects that are lacking in state-of-the-art peer-to-peer overlay systems. Our research will lead to fundamental advances in the design of Internet-scale, overlay networks for performance-demanding applications in adversarial environments.
