Abstract

This thesis focuses on creating tools for the gathering and management of data for analyzing Denial of Service attacks on the advertisement-based synchronization mechanism used in the DirectDemocracyP2P application. In this report we present two tools that were developed as part of this e ort: AttackerClient and Decoding and Distribution. These tools are used to perform the attack and analyze the captured network packets of the attack data, storing them in a database. The Decoding and Distribution tool can distinguish between di erent types of messages. It can also assemble fragmented messages from UDP chunks. The created tools help to manage a database of captured messages. A sample database is built with captured real and simulated data. A solution to the Denial of Service attack is implemented and tested.
