Goals

This module gives an in-depth introduction into methods and techniques for unobservable and anonymous communications in computer networks. The basic principles will be explained and exemplified. More specific the following schemes will be discussed: Ring Network, Private Message Service, Mixes, DC-Net. Besides anonymity and unobservability on the network layer techniques for anonymity and pseudonymity on the application layer will be explained.
