Bachelor's Theses and Projects

  • Liveness-Check for face recognition (Project)

Smart environments are increasing in popularity. In the CDL Digidow (digidow.eu) users can interact with various sensors in the physical world. These sensors recognize people based on different modalities. In our prototype we use face recognition. In order to prevent presentation attacks (e.g. showing an image/video of a person) this thesis will focus on researching state-of-the-art liveness detection modules and implementation and integration into the Digidow prototype.

  • Sensor node communication via ephemeral Tor Onion services

Abstract: The goal of this project is to create a library for simple machine-to-machine communication via short-lived hidden Onion services.

  • Security analysis of the Linux kernel in Mikrotik RouterOS

Abstract: Mikrotik RouterOS is a Linux kernel based embedded operating system for network routers, switches, access points, etc. While the userspace components are closed source, patches and configuration options for the used Linux kernel are available. The goal of this project is to analyze which security vulnerabilities - especially remotely exploitable ones - are publicly known for the user kernel version and if/how they have been patched. Necessary skills for this project include reading/writing C, reading and applying patches to source code, and compiling and testing native C code.

  • Android Device Security Database: Network monitoring

Abstract: The goal of this project/thesis is to automate monitoring of network traffic from Android devices. An OpenWRT based access point grants device-specific access to Android devices through 802.1x authentication. All network traffic from each device should be monitoring in terms of statistical data (number of packets, data volume, etc.) and classified on higher levels (e.g. HTTPS traffic, collecting the set of external hosts a device connects to, etc.). These network data traces should be collected systematically in a database for analysis including daily statistics for idle devices, traffic during and after a firmware update, and other interesting features.

  • Comparison of DNS results for TOR exit node DNS queries against different providers

As seen by a recent incident at our TOR exit node, where the ISP DNS servers manipulated the outcome of certain DNS queries through a DNS filtering system, interception at the level of DNS results is a popular (though questionable) means to block unwanted web traffic.

In this bachelor's thesis, the outcome of presenting DNS queries performed by our TOR exit node to multiple different providers should be analyzed. Moreover, cases where deviating responses are observed should be further investigated. Interesting deviations would be primarily those caused by filtering/censorship.

  • Analysis and implementation of the iButton/1-Wire protocol (ELECTRONICS SKILLS REQUIRED)

The goal of this bachelor thesis project is to analyze the iButton®/1-Wire® protocol, opens an external URL in a new window and to build an environment for reading and emulating iButton slave devices.

  • Implement a VoIP tap for Softphones (i.e. VoIP phones implemented as software running on a PS)

This should copy the network traffic and/or the sound output. This should then be run through libraries (to be obtained: Open Source like https://www.informatik.uni-augsburg.de/lehrstuehle/hcm/projects/tools/emovoice/, opens an external URL in a new window) and speaker detection. This should then show feedback about who is talking how much (e.g. percent) and the mood of the speakers.

  • Reconstructing internet video from a network trace

This should work for IP video telephony, but potentially also for other communications. The main task here is to handle missing parts, e.g. keeping the old picture or replacing it with "white/black screen". The sniffed traffic should then be playable and be accompanied by exact specifications what was found, and what/when there were "holes" filled.

  • Online-Nachsuche

Software zur genauen und beweissicheren Dokumentation von Aktionen und Daten, die z.B. beim forensischen Zugriff auf einen fremden Webmail-Account erfolgen

  • Asterisk als Anonymisierungsserver

Eingehende Telefonate weitervermitteln, ähnlich zu TOR (evtl. mittels VoIP + Ausgangsserver etc.)

  • Traces in Executables

Wie viele/welche Spuren bleiben bei verschiedenen Arten ein Programm zu übersetzen in der ausführbaren Datei zurück, die zum Account/Computer zurückführen? Sowohl direkt ("Das war Benutzeraccount X") als auch bei Zugriff auf diesen Computer ("Wurde sicher auf diesem Computer übersetzt") bzw. allgemein ("Muss Windows 8.1 gewesen sein").
