Publications and Talks
Research on Privacy Deficiencies of DNS (Dissertation)
In his PhD thesis Dominik focused on the privacy deficiencies of the Domain Name System, inference attacks, behavior-based tracking of users, and lightweight privacy enhancing technologies for DNS. The title of the thesis is (in German): „Beobachtungsmöglichkeiten im Domain Name System: Angriffe auf die Privatsphäre und Techniken zum Selbstdatenschutz“ (entry in DNB, entry in UHH Informatics Library). The PhD thesis has been published by Springer-Vieweg in 2016 (ISBN: 978-3-658-13262-0, eBook on SpringerLink)
- Allgemein verständliche Darstellung ausgewählter Ergebnisse (in German, 3 pages)
- Zusammenfassung der Ergebnisse der Dissertation (in German, 10 pages)
The PhD thesis has received three research awards: the „Dissertationspreis 2014“ of the Germany Informatics Society (Gesellschaft für Informatik) for the best computer science dissertation in Germany, Austria and Switzerland, the „GI/CAST Promotionspreis IT-Sicherheit 2014“ for the best information-security-related dissertation in Germany, and the „Wissenschaftspreis 2014“ of Gesellschaft für Datenschutz und Datensicherheit (GDD e.V.), which recognizes significant contributions to privacy. The main contributions of the thesis have also been published separately: The behavior-based tracking technique mentioned above has been published in an article that appeared in Computers & Security. The results on range queries have been published in a paper presented at IFIP SEC 2014, additional privacy-enhancing technologies for DNS are discussed in an ESORICS 2011 paper.
Research on Website Fingerprinting (Diploma Thesis)
Dominik's diploma thesis focused on website fingerprinting i.e., traffic analysis attacks that enable an adversary to infer the websites a user downloads over encrypted connections. The thesis received the 2008 research award of Gesellschaft für Datenschutz und Datensicherung (GDD e.V.) and won the 2008 CAST Thesis Award (1. Platz beim CAST-Förderpreis 2008 in der Kategorie Master-/Diplomarbeiten). Selected results on website fingerprinting have been published in a paper at CCSW 2009. The website fingerprinting dataset mentioned in the paper is available online (the location changed since the paper was published).

Research Grants and Projects
Dominik is PI at UHH for the following project:
H2020 CSA CANVAS (2016–2019) – Constructing an Alliance for Value-driven Cybersecurity: The consortium will take three domains of application with unique value-profiles and complementing cybersecurity exigencies – the health system, finance, and police / national security – as starting point for outlining problems related to value-driven cybersecurity. Using a three-step process, CANVAS will (1) structure existing knowledge, (2) design a network for exchanging knowledge and generating insights across domains, and (3) disseminate the insights gained through three means: A reference curriculum for value-driven cybersecurity with a focus on industry-training, briefing packages for policy stakeholders, and a MOOC (massive open online course) on value-driven cybersecurity.
Dominik is involved in the following research projects:
BMBF AN.ON-Next (2016–2019) – Anonymity Online Next Generation: This project has the long-term vision to integrate privacy enhancing technologies into the infrastructure of the Internet to make them available and usable for everyone. To this end, the project will look into lightweight techniques that provide a basic level of protection as well as fundamental approaches that allow to provide strong protection without sacrificing bandwidth and latency. The concepts will be implemented and pilots will be evaluated with business partners.
BMBF AppPETs (2016–2019) – Privacy Enhancing Technologies for Mobile Apps: This project aims to make it easier for developers to integrate privacy enhancing technologies into their smartphone apps. The project will set up a privacy infrastructure, which enables users to verify the protection of their personal data. Moreover, the project will study fair business models that are accepted by both vendors and users
BMBF DREI (2016–2018) – Datenschutzrespektierende Erkennung von Insidern: We will design a distributed solution for security control centers that allows to detect insider attacks via anomaly detection. The project strives for high acceptance by implementing legal requirements regarding the privacy rights of employees
