Web-basierte Oberfläche zur Gestaltung von Chatbot-basierten Konversationen
Bachelorarbeit
Institute of Distributed Systems,
2019
in Vorbereitung

Marker: ABSCHLUSSARBEIT BACHELOR BA DominikMeissner misc

Zusammenfassung: Gemeinsam mit Abteilungen aus der Psychologie wird am Institut für Verteilte Systeme ein programmierbarer Chatbot entwickelt, der insbesondere für Studien und Experimente eingesetzt werden soll. Der derzeitige Prototyp erfordert eine Programmierung der Zustandsautomaten des Bots in Java. Dies ist vor allem für Personen ohne Programmierhintergrund eine große Hürde bei der Gestaltung von Dialog-Skripten. In dieser Abschlussarbeit soll hierfür eine webbasierte Oberfläche entwickelt werden, die eine grafische Erstellung von Chatbot-basierten Studien ermöglicht. Im Rahmen der Arbeit soll zunächst ein Überblick über bestehende Tools und Formate erarbeitet werden. Anschließend soll der Funktionsumfang des Bots in einer interaktiven Web-Anwendung abgebildet werden. Die so modellierten Dialoge sollen schließlich in code-basierte Zustandsautomaten zur Ausführung in der Bot-Plattform trans-formiert werden.

Blockchain Analysis with Chronograph
Bachelor's thesis, Master's thesis or individual lab project
Institute of Distributed Systems,
2018
in Vorbereitung

Marker: PROJEKT, AA, BA, MA, BenjaminErb, FrankKargl, sidgraph, distributed, DominikMeissner

Zusammenfassung: Blockchain technology allows for decentralized, distributed, and secure ledgers that store records (e.g., transactions). Popular blockchain-based systems such as Bitcoin and Etherum have emerged as so-called crypto-currencies. As the ledger maintains the full history of transactions, interactions within the system are always persisted. In this work, the student is asked to design and implement online and offline transaction analyses based on Chronograph, a data processing platform for evolving graphs developed at our Institute. Therefore, different blockchain-based systems should be surveyed and appropriate analysis mechanisms should be conducted.

Entwicklung einer Softwarekomponente für einzigartige Signaturen mit Intel SGX
Abschlussarbeit, Projekt
Institute of Distributed Systems,
2018
in Vorbereitung

Marker: ABSCHLUSSARBEIT PROJEKT Bachelor BA FranzHauck VAPS

Zusammenfassung: Replizierte Systeme basieren oft auf Einigungsalgorithmen. Im Falle von beliebigen (byzantinischen Fehlern) werden N = 3f+1 Replikate benötigt bei f zu tolerierenden Fehlern. Mit Hilfe von vertrauenswürdigen Komponenten kann dies auf N = 2f+1 reduziert werden. Ein so genannter USIG ist so eine Komponente. Sie signiert eine Nachricht und zählt dabei eine von außen unveränderliche Sequenznummer hoch. Aufgabe der Arbeit ist es, ein Konzept und eine Implementierung mit Hilfe von Intel SGX zu entwickeln, die aus einer Java-Anwendung heraus genutzt werden kann. Herausforderungen ist neben der Implementierung die geeignete Initialisierung der Komponente.

Data-Centric Misbehavior Detection in Platooning
Bachelor Thesis
Institute of Distributed Systems,
2018
in Vorbereitung

Marker: ABSCHLUSSARBEIT BACHELOR BA RensVanDerHeijden sec

Zusammenfassung: In recent years, much research has been devoted to the design and implementation of vehicle-to-vehicle communication, based on a variety of communication technologies. Current standards foresee an ad-hoc communication architecture, where vehicles interact with other vehicles without the need for infrastructure. A major concern in such a network is the integrity and correctness of the exchanged information. Although solid proposals exist to protect message integrity, the detection of incorrect messages (misbehaviour detection) is a domain where there is no agreed-upon solution. At the institute of distributed systems, we are developing the Maat framework, which is designed to collect messages and apply misbehaviour detection mechanisms to determine which messages are valid. We use techniques from information fusion and trust management to establish trustworthiness of messages and vehicles. For validation of our framework, we are looking for a student interested in designing novel attacks to test the reliability of our framework. In particular, we are interested in attacks designed to be difficult to detect, either by combining multiple attack strategies or designing new ones. These attack should be developed within the VEINS framework, a C++-based simulation library for vehicle-tovehicle communication.

Mödinger, David
Verwirklichung eines Privatsphäre garantierenden Broadcast Protokolls
Masterarbeit
Institute of Distributed Systems,
2019
in Vorbereitung

Marker: ABSCHLUSSARBEIT MASTER MA DavidMoedinger networks

Zusammenfassung: Die Verbreitung von Transaktionen in Blockchain-Netzwerken kann viele Informationen über deren Nutzer preisgeben. Ins- besonder muss die Vertraulichkeit von Zahlungsinformationen geschützt werden. Um diesen Schutz zu erreichen, haben wir ein Protokoll entworfen, welches die Privatsphäre dieser Trans-aktionen gewährleistet und Entwicklern die nötige Flexibilität für verschiedenste Anwendungsszenarien bereitstellt. Doch es bleiben viele offene Fragen für die Umsetzung in der Praxis, beispielsweise die Anpassung an praktische Begebenheiten und die Erstellung der nötigen Gruppen. Ziel dieser Arbeit ist es, einige der offenen Fragen zu klären und das Protokoll im Rahmen einer Proof-of-Concept-Implementierung zu evaluieren. Geeignet für Studierende mit Erfahrung Netzwerkprogrammierung. This project can also be completed in English. Please contact me for further details.

Controlled Neurofeedback using Mobile EEG and Smartphone
Master's thesis
Institute of Distributed Systems,
2018
in Vorbereitung

Marker: ABSCHLUSSARBEIT, THESIS, Master, AA, MA, MuntazirMehdi, mobile, misc

Zusammenfassung: Neurofeedback provides the necessary means to visualize selected and controlled parameters of the brain activity. In healthcare domain, neurofeedback studies enable mitigation of many psychological disorders and illnesses, mainly by therapies that help patients to better self-regulate their brain activity. Electroencephalography (EEG) is the method of monitoring the electrical activity of the brain, thus providing the necessary feedback. In this thesis work, the student is required to survey the current state of frameworks, techniques, or methods that enable coupling of Mobile EEGs with Smartphones. Bluetooth 2.1 with Enhanced Data Rate (EDR) capability is one of the most effective mean of coupling EEGs with Smartphones. The student would therefore be required to work on the Bluetooth stack to acquire real-time data generated from the Mobile EEGs, parse the electrical signal, and visualize the signal semantically. For successful completion of the thesis, the student would be required to identify and address any one of the open challenges faced by the proposed topic. An example of this can be addressing the bandwidth challenges, battery consumption, or signal accuracy

Engelmann, Felix
Blockchain Explorer
Projekt
Institute of Distributed Systems, Ulm University,
2017
in Vorbereitung

Marker: PROJEKT, FelixEngelmann

Zusammenfassung: In dem Projekt soll eine Webanwendung entstehen, die Daten aus einer Blockchain visualisiert und mit zusätzlichen Informationen aufbereitet. Für die bekannten Blockchains wie Bitcoin und Ethererum existieren Portale wie z.B. etherscan.io , die detaillierte Informationen über die jeweilige Blockchain anzeigen. Für den Einsatz in der Industrie sind diese öffentlichen Blockchains jedoch nicht zuverlässig genug. Deshalb betreut das SAMPL Projekt eine eigene Blockchain, die auf Ethereum aufbaut und speziell für Lizenzverwaltung ausgerichtet ist. Dafür soll nun ein Explorer entwickelt werden der den gleichen Komfort bietet wie die existierenden Plattformen. Die Rohdaten können per REST API bezogen werden, sollten dann aber für die Verwendung aufbereitet werden und in einer durchsuchbaren Datenbank abgelegt werden. Die UI sollte durch eine zeitgemäße Webseite geschehen. Testprojekte gibt es mit node.js und angular, jedoch ist verwendete Technologie egal, solange die Software zuverlässig im Produktivbetrieb eingesetzt werden kann.

Privacy Management using Differential Privacy in ITS
Master- oder Diplomarbeit
Institut für Verteilte Systeme, Universität Ulm,
April 2013
in Vorbereitung

Marker: MA, DA, AA, FrankKargl, privacy, mobile

Zusammenfassung: Joint project between University of Ulm, Germany and NICTA Sydney, Australia. Differential Privacy is a rather new concept that enables practically feasible privacy controls and formal guarantees to be implemented. In a recent publication, we have started to look how Differential Privacy can be used in the context of Intelligent Transportation Systems and Car-to-X communication and have identified a couple of open challenges. We have outlined how differential privacy can be integrated into the PRECIOSA Privacy-enforcing Runtime Architecture and identified a number of future research questions one being how to manage the appearing trade-off between data accuracy, privacy, and availability of data. The master thesis requires to work into the fields of Differential Privacy, Intelligent Transportation Systems, and the PRECIOSA project results based on available literature and material followed by conceptual work that should extend our existing proposal. A proof-of-concept implementation should then allow some practical analysis of the feasibility and achievable data accuracy based on Floating Car Data captured in real experiments. There is the option to work on the thesis during an internship at the NICTA in Sydney, Australia. Because of the need to apply for travel funding, this would require a longer-term planing before starting the work.
