Khattat, Mostafa (author)Threshold signatures play a crucial role in the security of blockchain applications. An efficient threshold signature can be applied to enhance the security of wallets and transactions by enforcing multi-device-based authentication, as this requires adversaries to compromise more devices to recover the key. Additionally, threshold signatures can...master thesis 2024

Stokkink, Q.A. (author)The digital world is evolving toward representing - and serving the interconnection of - natural persons. Instead of depending on the intrastructure of Big Tech companies and governments, users can cooperate and use their hardware to form public infrastructure. Instead of existing by virtue of a reference in some institution's database, users...doctoral thesis 2024

van Gend, Thijmen (author)Privacy-enhancing technologies (PETs) have historically been used for safeguarding individual privacy from both public and private interference. But lately, tech companies have started using PETs as one instrument for the expansion of their power over different actors, as appears to be unfolding in the case of Amazon’s Sidewalk service: a United...master thesis 2024

Coggins, T.N. (author)In the introduction of this thesis, I contend that robot ethics, as a research field, generally treats privacy as the appropriate distribution of information, and therefore overlooks privacy concerns raised by robots beyond this conceptualization’s purview. I illustrate this contention by evaluating a hypothetical case involving a household...doctoral thesis 2024

Kouwenhoven, Robin (author)Foremost among the challenges of the Bitcoin blockchain is the scalability bottleneck. To address this issue, the Lightning Network, a payment channel network, was created. Lightning is a payment channel network that is source-routed and uses onion routing, like Tor. However, unlike Tor, the routing path is determined by optimizing a cost...master thesis 2024

Out, Annabelle (author)This project explores the prospects for interior design in a dual purpose train that can run both day and night for improved utilization and comfort.<br/><br/>Contemporary trains are categorized as either exclusively for daytime or nighttime use. Their interiors limit them to specific temporal contexts. For instance, in daytime trains,...master thesis 2024

Bestebreur, Timon (author)The versatility of the internet enables many applications that play an increasingly bigger role in our society. However, users have little control over the route that their internet traffic takes, which prevents them from controlling who sees their packets and how their traffic is handled. Researchers have proposed an extension to the internet,...master thesis 2024

Van Opstal, Quinten (author)Federated learning provides a lot of opportunities, especially with the built-in privacy considerations. There is however one attack that might compromise the utility of federated learning: backdoor attacks [14]. There are already some existing defenses, like flame [13] but they are computationally expensive [14]. This paper evaluates a version...bachelor thesis 2024

Ghasia, Zahra (author)The use of Electronic Health Records (EHRs) has seen a breakthrough in clinical research for personalized treatments (Hamburg & Collins, 2010.) Despite the potential advantages of vast EHR data available, constraints of privacy and legislation hinder its use (Rieke et al., 2020.) Health data exists in an interconnected healthcare system ...master thesis 2024

Li, Martin (author)In recent years, the rapid advancements in big data, machine learning, and artificial intelligence have led to a corresponding rise in privacy concerns. One of the solutions to address these concerns is federated learning. In this thesis, we will look at the setting of vertical federated learning based on tree models. We have built a system that...master thesis 2024

Musick, Geoff (author), Duan, Wen (author), Najafian, S. (author), Sengupta, Subhasree (author), Flathmann, Christopher (author), Knijnenburg, Bart (author), McNeese, Nathan (author)Newly-formed teams often encounter the challenge of members coming together to collaborate on a project without prior knowledge of each other’s working and communication styles. This lack of familiarity can lead to conflicts and misunderstandings, hindering effective teamwork. Derived from research in social recommender systems, team...journal article 2024
