    Automated Monitoring of Operational Technology Security and Compliance for Power Grids
    (GI SICHERHEIT 2022, 2022) Fraune, Bastian
    IT security standards can increase trust in a system or component if compliance to the standard can be proven to third parties. Those standards usually specify requirements for security features, which then lead to a certain configuration of an industrial control system. Continuous monitoring of IT security configurations on intelligent electronic devices is difficult because there is no standardised way to query the security configurations of those devices. The objective of this PhD project is to enable automatic querying of security settings from industrial control system in the use case of the power grid infrastructure for remote monitoring. This opens up the possibility of automatically comparing the actual security state on the device against the defined IT security standard configurations. In such cases, industrial control systems that do not comply with defined security standards can thus be identified directly by monitoring systems in the control centre.

    Capturing trust in public service encounters: Mapping trust along life event citizen journeys
    (7. Fachtagung Rechts- und Verwaltungsinformatik (RVI 2024): Neue Wege der Zusammenarbeit und Vernetzung für digitale Transformation und Verwaltungsmodernisierung, 2024) Nowak, David
    Understanding and fostering citizen trust is crucial for effective public service delivery, where citizens must take risks vis a vis the state, or where collaboration and adherence to rules is especially important. This article proposes a systematic approach to develop a deeper comprehension of how trust is gained and lost during specific service interactions. Building on prior work on where trust may be gained or lost in a generic citizen journey [Di22b] this article proposes identifying life event services, where trust is particularly important and creating citizen journeys, from the perspective of relevant segments of the population.

    Collaborating in a Crisis: Perspectives on Trust and Technological Framework in Organising a COVID-19 Online Hackathon
    (Mensch und Computer 2022 - Tagungsband, 2022) Karhu, Mari; Karampela, Maria; Häkkilä, Jonna
    This paper explores trust in online-only-collaboration, where a team was gathered to organise a COVID-19 online hackathon with only three days notice. The study is based on the thematic analysis of ten in-depth interviews with the hackathon organisers. The findings report how trust among the organisers was encapsulated in 1) the shared big goal, 2) the significance of real-life networks, 3) a strong lead organiser on the collaboration forming on the fly, and 4) the lack of face-to-face contact in relation to becoming familiar or staying unknown. Technology related findings showed that the collaboration platforms were selected based on familiarity and ease of use. The chosen communication channels created a split between age groups, and transparency of the communication suffered somewhat from one-to-one communications in the background and divided application use. However, trust between the organisers helped them to overcame the transparency challenges. The findings are applicable to societal crisis situations in which technologies are used to build collaboration in aim to address shared challenges.

    Die Rolle der Kultur in der Selbstoffenbarung und Privatsphäre in sozialen Onlinenetzwerken
    (Wirtschaftsinformatik: Vol. 54, No. 3, 2012) Krasnova, Hanna; Veltri, Natasha F.; Günther, Oliver
    Soziale Onlinenetzwerke (SON) stützen sich ausschließlich auf nutzergenerierten Inhalt um ihren Mitgliedern ein ansprechendes und lohnendes Erlebnis zu bieten. Infolgedessen sind die Belebung der Kommunikation zwischen Nutzern sowie die Stimulierung ihrer Selbstoffenbarung im Netz unerlässlich für die Zukunftsfähigkeit von SON. Soziale Netzwerke sind weltweit beliebt und deren Nutzer werden zunehmend kulturell vielfältiger. Um ihre Mitglieder zu motivieren Informationen zu teilen bedarf es des Verständnisses kultureller Feinheiten. Bisher bietet die derzeitige Forschung nur begrenzte Einblicke in die Rolle der Kultur, die hinter dieser Bereitwilligkeit von Selbstoffenbarung der Nutzer in Onlinenetzwerken steht. Aufbauend auf dem Privatsphärekalkül untersucht diese Studie die Rolle zweier kultureller Dimensionen – Individualismus und Unsicherheitsvermeidung – bei der Selbstoffenbarung auf SON. Die Umfrageergebnisse deutscher und amerikanischer Facebook-Nutzer bilden hierbei die Basis für die Analyse. Die Resultate des Strukturgleichungsmodells und der Multi-Gruppen-Analyse offenbaren deutliche Unterschiede in den kognitiven Strukturen dieser beiden Kulturen. Hierbei spielen Vertrauensannahmen eine entscheidende Rolle bei der Selbstoffenbarung von Nutzern mit individualistischem Hintergrund. Gleichzeitig beeinflusst die Unsicherheitsvermeidung die Auswirkung von den Bedenken hinsichtlich der Privatsphäre. Der Beitrag der Autoren zu der Theorie ist die Ablehnung des universellen Charakters des Privatsphärekalküls. Die Forschungsergebnisse geben den Betreibern von SON eine Reihe von Empfehlungen, um die Erstellung und Teilung von Inhalten ihrer heterogenen Zielgruppen zu stimulieren.AbstractSocial Network Sites (SNSs) rely exclusively on user-generated content to offer engaging and rewarding experience to its members. As a result, stimulating user communication and self-disclosure is vital for the sustainability of SNSs. However, considering that the SNS users are increasingly culturally diverse, motivating this audience to self-disclose requires understanding of their cultural intricacies. Yet existing research offers only limited insights into the role of culture behind the motivation of SNS users to self-disclose. Building on the privacy calculus framework, this study explores the role of two cultural dimensions – individualism and uncertainty avoidance – in self-disclosure decisions of SNS users. Survey responses of US and German Facebook members are used as the basis for our analysis. Structural equation modeling and multi-group analysis results reveal the distinct role of culture in the cognitive patterns of SNS users. The authors find that trusting beliefs play a key role in the self-disclosure decisions of users from individualistic cultures. At the same time, uncertainty avoidance determines the impact of privacy concerns. This paper contributes to the theory by rejecting the universal nature of privacy calculus processes. The findings provide for an array of managerial implications for SNS providers as they strive to encourage content creation and sharing by their heterogeneous members.

    Distributed ascending proxy auction — A cryptographic approach
    (Wirtschaftsinformatik: Vol. 48, No. 1, 2006) Rolli, Daniel; Conrad, Michael; Neumann, Dirk; Sorge, Christoph
    In recent years, auctions have become a very popular price discovery mechanism in the Internet. The common auction formats are typically centralized in nature. The peer-to-peer paradigm demands gearing up auctions for decentralized infrastructures. In this context, this paper proposes a distributed mechanism for ascending second-price auctions that relies on standard cryptographic algorithms. In essence, the auction protocol has the capability of preserving the privacy of the winning bidder’s true valuation.The auction protocol makes use of a high number of auctioneers divided into several groups. A bidder creates an encrypted chain of monotonously increasing bidding steps, where each bidding step can be decrypted by a different auctioneer group. This considerably reduces the attack and manipulation possibilities of malicious auctioneers. In addition, this secure approach does not require bidders to be online unless they are submitting their bid chain to the auctioneers.

    The effect of anthropomorphic design on the perceived trustworthiness of AI-based assistance systems
    (Mensch und Computer 2024 - Workshopband, 2024) Reuter, Muriel
    Artificial intelligence (AI) has become an omnipresent part of everyday life and increasingly also of the world of work. The design of human-AI interaction plays a crucial role in this context. This project aims to analyze the effect of anthropomorphic design elements on perceived trustworthiness. Positive and negative consequences are to be investigated in a mixed-methods approach in realistic laboratory settings. The aim is to develop guidelines for the design of anthropomorphic AI systems in a work context.

    GRAIN: Truly Privacy-friendly and Self-sovereign Trust Establishment with GNS and TRAIN
    (Open Identity Summit 2024, 2024) Schanzenbach, Martin; Nadler, Sebastian; Johnson Jeyakumar, Isaac Henderson
    Robust and secure trust establishment is an open problem in the domain of self-sovereign identities (SSI). The TRAIN [KR21] concept proposes to leverage the security guarantees and trust anchor of the DNS to publish and resolve pointers to trust lists from DNS. While the DNS is a corner stone of the Internet, its continued use is primarily a consequence of inertia due to its crucial function as the address discovery system for existing Internet services. Research and development in the area of SSI is — for the most part — green field. The choice of DNS as a core building block appears fainthearted given its open security issues. Recently, the IETF paved the way to experiment with alternative name systems in real world deployments by reserving the special-use top-level domain “.alt” in the domain name space [KH23]. This allows us to use alternative name systems such as the GNU Name System (GNS) [SGF23a] without intruding into the domain name space reserved for DNS. In this paper, we show how we can use the GNS as a drop-in replacement for DNS in TRAIN. We show how TRAIN-over-GNS (GRAIN) can deliver security and privacy improvements the security concept of TRAIN-over DNS and show that it is practically feasible with limited modifications of existing software stacks.

    In Stars We Trust – A Note on Reputation Portability Between Digital Platforms
    (Business & Information Systems Engineering: Vol. 64, No. 3, 2021) Hesse, Maik; Teubner, Timm; Adam, Marc T. P.
    Complementors accumulate reputation on an ever-increasing number of online platforms. While the effects of reputation within individual platforms are well-understood, its potential effectiveness across platform boundaries has received much less attention. This research note considers complementors’ ability to increase their trustworthiness in the eyes of prospective consumers by importing reputational data from another platform. The study evaluates this potential lever by means of an online experiment, during which specific combinations of on-site and imported rating scores are tested. Results reveal that importing reputation can be advantageous – but also detrimental, depending on ratings’ values. Implications for complementors, platform operators, and regulatory bodies concerned with online reputation are considered.
