This dissertation consists of two parts. The main thesis of the first part is that secret, two--party communication cannot be prevented on the Internet, regardless of filtering methods. We show how partners can arrange a channel for further communication despite active filtering. We examine covert channels on all layers of the TCP/IP stack and its main application protocols. We describe anonymizing techniques and their limits in certain scenarios. By combining covert channels in a popular protocol and anonymization we develop a messaging protocol which allows unobservable communication.
In the second part of the dissertation we present a protocol for the interactive validation of database replies. The protocol is efficient in the number and size of the messages exchanged. A special property is that even the non--existence of records can be verified efficiently.
