Contents | | The lecture covers:
Chapter 1: Peer-to-Peer Systems (40 %)
Chapter 2: Security (30 %)
Chapter 3: Anonymity (30 %)
Peer-to-Peer Systems and Overlay Networks cause a major part of the traffic on the Internet. The lecture presents the mechanisms and protocols of such networks and explains a set of selected systems. BitTorrent allows an efficient and cooperative transfer of large files. Structured Peer-to-Peer Systems like Distributed Hash Tables allow an efficient lookup for index pointers or nodes in a scalable, efficient, and robust way. The security chapter focuses on advanced non-standard issues of network security. The primary focus is on security issues that are related to Peer-to-Peer Systems. The last chapter is about anonymity on the Internet and it discusses mixes and re-routers as well as systems like Tor and Gnunet.
