  • Physical user location model using machine learning

Abstract: Smart environments are increasing in popularity. In the CDL Digidow (digidow.eu) users can interact with various sensors in the physical world. In order to enhance the sensors ability to rapidly fulfill the users request(s), it could predict the users location and thus infer the most probable action in the future. The goal of this project is to create a prediction about the user location in the immediate future, based on various inputs, such as videos and smartphone sensors (IMU), by e.g. calculating movement vectors.

  •  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.

  • Security of e-scooters

TIER, Arolla, Wind, Lime, voi. ... after only two month e-scooters are all over Linz. The idea has been picked up pretty well and even the StVO (traffic rules) is going to be updated to bring (legal) clarity for the use of them. Besides all the positive voices, there is also quite some criticism, mainly about cityscape and safety. Above that, pushing to the market in such a short time frame also has the potential that security considerations have been left behind. Therefore, we are interested in various aspects of e-scooter security and have a few topics for master theses/projects to work on.

  • Tracking of persons through Wi-Fi sniffing

The goal of this project is to passively collect and analyze Wi-Fi (802.11) packets with regard to information that could be used to track or even identify an individual person. In particular, 802.11 management frames such as probe requests seem to broadcast usable information.
As a first step, you need to build an environment to passively collect (sniff) Wi-Fi communication and to extract the relevant data (possibly based on existing open source projects). Using that environment, you will collect and analyze data emitted from various mobile devices (particularly different smartphones, typically carried around in everyones pockets). Finally, you should be able to evaluate if that data could be used to track someone's movements around a building.

  • Injecting URLs and other data to Smart TVs via DVB-T

The Institute of Networks and Security has software defined radio hardware that should be suitable to create and inject DVB-T signals into receivers such as Smart TVs. The aim of this thesis is to reproduce and potentially extend the work shown in https://www.youtube.com/watch?v=bOJ_8QHX6OA on how injected HbbTV URLs are automatically opened/executed on some Smart TVs to allow a remote code execution.

  • Security analysis of the communication protocol of a MAVIC PRO drone

This project aims to investigate the two communication channels (Wi-Fi and a custom RF) of a commercial drone (http://www.dji.com/mavic?from=v3_landing_page) and analyze the used communication protocol. Using a software defined network and state-of-the-art reverse engineering tools, your goal is to find potential security weaknesses and make suggestions on how to improve the existing protocols.

  • Smart home security: preventing privacy leaks with home routers
  • E-Learning System für Websites am Beispiel RIS

Beispiels-Suchaufgaben mit Beobachtung des Benutzers (Eingabe, Mausbewegungen etc.) und adaptiven Reaktionen darauf (Verbesserungsvorschläge, Vorzeigen mit Maus&Eingabe + Audio-Kommentar); Zwei Varianten (ca. 10 Min. für Laien, ca. 90 Minuten für Profis)

  • VM ressource usage verification

Unter Hype-V kann man den Ressourcenverbrauch einer VM genau messen. Kann man Software so ändern, dass sie regelmäßig Logging an Drittmaschinen ausgibt, wie viel Arbeit sie verrichtet hat? Kann man dies dann mit den Hyper-V-Messungen vergleichen? Kann man daraus feststellen, ob zusätzliche Software (= Malware) in der Maschine läuft bzw die Abrechnung zumindest ungefähr korrekt ist? Implementierung eines Beispiels an einem Webserver (plus Datenbank intern oder separat sowie Zugriff auf externe Webressourcen). Relevant: CPU-Last/Nutzung, Disk-Nutzung, Bandbreite – nicht unbedingt absolut aber z.B. nach einer Kalibrierungsphase.

  • Translate security protocols specified in Alice&Bob notation to Scyther language

Alice&Bob notation has been widely used to describe security protocols. However, protocol verification tools such as ProVerif, Scyther, and Tamarin have their own specification language. We are therefore interested in developing a tool that allows translating an Alice&Bob specification to other languages that can then be used as input to different verification tools. The goal of this particular task is to build a tool that translates an Alice&Bob specification to Scyther specification. As Scyther does not support equational theories that are often used to model for instance Diffie-Hellman exponentiation, not all Alice&Bob specifications are convertible to Scyther's language. Nevertheless, many protocols such as Kerberos and Needham-Schroeder variants are translatable.

  • Extend JPLAG to support assembly language

JPLAG: https://jplag.ipd.kit.edu/
Ideally in a generic way, so Gnu/Intel syntax is both possible (perhaps even interchangeable!), and also different processor architectures.
