2017
noch nicht publiziert

Marker: AA, BA, StephanKleber, FrankKargl, itsec, networks

Zusammenfassung: Task of this thesis is to implement and evaluate natural language processing methods, like Latent Dirichlet Allocation and Information Bottleneck as feature extraction and clustering methods for network messages. They are intended to be implemented for use in type-based alignment of message tokens according to the approach Discoverer.

OBD Data-Logger for Driving Behaviour Analysis
Project
Institute of Distributed Systems, Ulm University,
2017
noch nicht publiziert

Marker: MatthiasMatousek, DominikLang, PROJEKT, AA

Zusammenfassung: Analysis of driving behaviour presents opportunities for security, but comes with implications for privacy. In order to conduct research in this field, driving data is required. The goal of this project is to implement tools that log driving data from a vehicle's OBD port. Further, a framework for data analysis — e.g. via machine learning mechanisms — should be provided.

Comparison of Homomorphic Encryption Scheme Implementations
Master Thesis, Project
Institute of Distributed Systems, Ulm University,
2017
noch nicht publiziert

Marker: AA, MA, PROJEKT, MatthiasMatousek

Zusammenfassung: Homomorphic Encryption (HE) -- the "holy grail" of cryptography -- allows computation on encrypted data without knowledge of the encryption keys. While it has been shown that both partially (only limited operations) as well as fully homomorphic crypto-systems (unlimited, arbitrary operations) are possible, they still come with substantial computation complexity and storage requirements. Goal of this work is to survey and compare HE scheme implementations. Properties of interest are their capabilities (partially vs. fully homomorphic), performance (speed and storage), as well as their favourable applications. The applicant should be familiar with IT security concepts (lecture "Security of IT-Systems") and cryptography (lecture "Kryptologie - Methoden und Algorithmen" and optimally "Privacy Engineering and Privacy Enhancing Technologies - PET"). They should further be interested in the application of different programming languages (such as C++, Python, Haskell, Java, and others). While no expert knowledge of programming languages is required, HE schemes are implemented in different languages, and thus, the willingness to explore these should be present. This topic is suitable for a Master thesis, or as a Master project.

Vergleich Statistischer Informationsverteilung in Peer-to-Peer Netzen
Bachelorarbeit
Institut für Verteilte Systeme, Universität Ulm,
2017
noch nicht publiziert

Marker: AA, BA, DavidMoedinger, networks, distributed, privacy, p2p

Zusammenfassung: With classical broadcast mechanism, a source detection algorithm is fairly successful. There exist proposals to break the symmetry and make source detection hard. In this thesis, two of those proposals, adaptive diffusion and dandelion, should be implemented in a simulator and evaluated for interesting characteristics in realistic networks.

Secure Reset: Transforming a Comprised System into a Secure State
Master's thesis or Diploma thesis
Institute of Distributed Systems, Ulm University,
2017
noch nicht publiziert

Marker: AA, MA, DominikLang

Zusammenfassung: Modern vehicles contain up to 100 ECUs (Electronic Control Units). These are interconnected via an on-board network and together form a complex computer system on wheels. Vehicles now also include various wireless communication systems, such as WiFi for infotainment, Bluetooth for TPMS (Tire Pressure Monitoring System), and cellular communication for backend services. It has been shown that it is possible to gain access to the internal network and compromise ECUs, for example by flashing the ECUs to add backdoors. Consequently, it is necessary to create methods for a secure bootstrapping process that resets all ECUs of a vehicle to a secure state after a compromise has been detected. With this scenario in mind, the goal of this Master's thesis is to create an architecture and respective strategies that allow for an over-the-air secure bootstrapping process. This process should be based on a security module, such as can been found in modern ARM processors. In addition, the student should create and evaluate a prototype implementation.

Improving position verification in VANETs
Bachelor Thesis
Institute of Distributed Systems, Ulm Univerisity,
2017
noch nicht publiziert

Marker: AA, BA, RensVanDerHeijden, networks, mobile, itsec

Zusammenfassung: One important use case for vehicular ad-hoc networks is to improve safety by giving vehicles communication capabilities, allowing them to respond to dangers earlier than autonomously operating vehicles, which must rely on their sensors alone. However, it is possible that vehicles transmit incorrect positions into the network. In this work, the goal is to detect such incorrect positions. This involves several steps; designing an attacker model, developing or implementing detection approaches, and evaluating the result. The implementation work will be in Java, within the Maat framework, a prototype detection framework under development at the institute of distributed systems.

DoS Attacks on Congestion Control Algorithms
Bachelorarbeit
Institut für Verteilte Systeme, Uni Ulm,
2016
noch nicht publiziert

Marker: AA, BA, ThomasLukaseder, itsec, networks

Zusammenfassung: Current TCP congestion control algorithms have many drawbacks, especially the introduction of new high-speed and low-delay congestion control variants is impaired by the aggressiveness of the existing variants. In context of a research project by the state of Baden-Württemberg, a new system for the coexistence of different congestion control mechanisms is currently in development. As this new system strongly depends on conform/honest behavior of network subscribers, DoS attacks paralyzing the network might be possible. This thesis shall evaluate possible attack vectors and methods to detect and mitigate or prevent successful attacks.

Identifikation optimaler Einsatzbereiche der Einigungsalgorithmen Paxos und Vertical Paxos
Masterarbeit
Institut für Verteilte Systeme, Universität Ulm,
2014
noch nicht publiziert

Schlüsselwörter: Paxos, State Machine Replication, Group Communication, Primary Backup

Marker: DA, MA, AA, ChristianSpann, FranzHauck

Zusammenfassung: Die beiden Einigungsalgorithmen Paxos und dessen Erweiterung Vertical Paxos sind strukturell grundverschieden. Das daraus resultierende, vermutlich sehr unterschiedliche Verhalten soll in dieser Arbeit in geeigneten Evaluationen untersucht und beschrieben werden. Der Unterschied der Verfahren ergibt sich in der Verteilung des Aufwands zur Fehlererholung. In Paxos kann jeder Knoten selbst direkt mit Fehlern umgehen, in Vertical Paxos gibt es einen externen Knoten, der das System überwacht.
