Analyzing Passive Background Traffic, Master Thesis, Internship Mobile devices like phones send and receive data even when they are not actively used. This background traffic might still be sufficient to distinguish multiple users, which would allow an adversary to identify and track users from encrypted network traffic. In this thesis, you build a measurement setup that enables to record the background traffic of multiple phones. You record traffic and analyze the feasibility of a tracking attack.
Spoofing the Controls of a Robot, Master Thesis, Internship 5G campus networks can be used to control machines in large industrial facilities, including manufacturing robots. In such environments, real-time communication is crucial, and any added latency can lead to issues for the production cycle. Consequently, additional security measures like integrity protection for user plane data can lead to unwanted overhead and remain disabled. An adversary can exploit this by spoofing the control commands sent to a machine. In this thesis, you build an experimental setup using a 5G network and a robot arm. You control the arm and conduct a spoofing attack that manipulates the control commands.
Implementation of a Signal Strength Measurement App, Bachelor Thesis, Internship Implement an Android app that allows to measure the signal strength of surrounding mobile network base stations. The thesis includes the design and implementation of the app as well as real-world measurements of signal strengths in an example area.
End-to-End Traffic Analysis Attacks in Mobile Networks, Bachelor Thesis Design and apply end-to-end traffic analysis attacks on 5G mobile traffic. The thesis focuses on the experimental evaluation of statistical attacks and their feasibility.
Remote SIM Implementation, Master Thesis Integrate a remote SIM setup into SRSRAN that allows to switch between multiple physical SIM cards within the software stack implementation of SRSRAN. Verify the correct behavior and conduct measurements in this setup.
Measurement Reports, Bachelor Thesis Use the information of LTE measurement reports to track users of a mobile network. The thesis includes the implementation of measurement report trigger events in srsRAN, and the simulation of a network setup with a focus on the mobility of uers.
