Master thesis feedback

by François Pönsgen

Hello list, I'm writing a master thesis on: "GSM and GPRS security using OsmocomBB". The goal of this thesis is to describe the various attacks made possible by the project, and to analyze their impact on Norwegian networks. I finally have an almost complete draft for all the chapters: the chapters 2 and 3 introduce the necessary background, chapter 4 describes the eavesdropping attack, chapter 5 describes various DoS attacks, and finally chapter 6 analyzes their impact on Norwegian networks. I'm looking for feedback on this thesis, and I thought that the topic might interest subscribers of this mailing list! I would really appreciate any constructive criticism on this report, so if you have any please do not hesitate to contact me. The deadline is on the 8th of June, in one week, so there is not much time left. The thesis is available here: https://gitlab.com/francoip/thesis/blob/public/thesis.pdf Thanks a lot, François Pönsgen
