- KonferenzbeitragA shared responsibility model to support cross border and cross organizational federation on top of decentralized and self-sovereign identity: Architecture and first PoC(Open Identity Summit 2023, 2023) Kubach, Michael; Henderson, Isaac; Bithin, Alangot; Dimitrakos, Theo; Vargas, Juan; Winterstetter, Matthias; Krontiris, IoannisThis paper discusses the challenges of transitioning from legacy federated identity systems to emerging decentralized identity technologies based on self-sovereign identities (SSI) and verifiable credentials, which are being used in initiatives such as Gaia-X and Catena-X for secure and sovereign data sharing. The adoption of SSI and decentralized identity technologies requires a standardized reference model that addresses challenges around trust in cross-border and crossorganizational federations based on decentralized identities. To facilitate this transition, the paper proposes a new Fed2SSI architecture that introduces a middle layer of abstraction for the policybased transformation of credentials, enabling interoperability between legacy federated identity solutions and SSI/decentralized identity environments. The architecture is implemented in a prototype and an exemplary use case is presented to illustrate the added value of this approach.
- KonferenzbeitragLifting the Veil of Credential Usage in Organizations: A Taxonomy(Open Identity Summit 2023, 2023) Bochnia, Ricardo; Richter, Daniel; Anke, JürgenWith the emergence of self-sovereign identity (SSI) as a paradigm for digital identity management the handling of verifiable credentials (VCs) has become an important topic in organizations. Organizations process a wide variety of documents which can be considered credentials. Previous research shows that a challenge in developing SSI systems is a lack of understanding of the core aspects of the paradigm and their relation to existing organizational practices. Our research focuses on the different characteristics of credentials in organizations and maps the characteristics of VCs to physical credentials. Our findings indicate that credentials in organizations can be classified by ten dimensions. Additionally, VCs have many possible characteristics of physical credentials, althoughmplementation and support for certain features may be vendor-specific. Finally, we provide insights and suggestions for SSI researchers and developers.
- KonferenzbeitragResearch on User Experience for Digital IdentityWallets: State-of-the-Art and Recommendations(Open Identity Summit 2023, 2023) Sellung, Rachelle; Kubach, MichaelDigital identity wallets are central components for Decentralised and Self-Sovereign Identity (SSI) approaches. They are the interface for users to manage their identities and gain access to services. Hence, the usability and user experience of these wallets is pivotal for the adoption of those popular and privacy friendly identity management concepts. As research on the user experience of wallets is still in its infancy, this paper aims to provide a first overview of recent research – published and from completed and ongoing research projects. Findings are summarized and recommendations for developers are derived.
- KonferenzbeitragModeling the Threats to Self-Sovereign Identities(Open Identity Summit 2023, 2023) Pöhn, Daniela; Grabatin, Michael; Hommel, WolfgangSelf-sovereign identity (SSI) is a relatively young identity management paradigm allowing digital identities to be managed in a user-centric, decentralized manner, often but not necessarily utilizing distributed ledger technologies. This emerging technology gets into the focus through the new electronic IDentification, Authentication and trust Services (eIDAS) regulation in Europe. As identity management involves the management and use of personally identifiable information, it is important to evaluate the threats to SSI. We apply the STRIDE (Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, and Elevation of Privilege) threat modeling approach to the core components of SSI architecture and the interactions between them. Based on the summarized results, we discuss relevant mitigation methods and future research areas.
- KonferenzbeitragThe possible impact s of the eIDAS 2.0 digital identity approach in Germany and Europe(Open Identity Summit 2023, 2023) Schwalm, SteffeneIDAS 2.0 introduces the EU Digital Wallet as the eID mean including not only the PID (eID Scheme) but also additional attributes like (qualified) attestation of attributes and gives the control over its identity back to the user in regulated approach. This means that eIDAS 2.0 gives the possibility to provide legal trust on decentralized digital identities in self-sovereign manner by combining existing trust model from eIDAS 1.0 with SSI-approach. The paper describes based on the legal proposal possible impacts of eIDAS 2.0 on German and European identity and trust services in order to provide framework for trustworthy digital transactions in EU and EFTA
- KonferenzbeitragExploring the Human Factor in IT-security: A mobile lab for Investigating User Behavior(Open Identity Summit 2023, 2023) Fähnrich, Nicolas; Köster, Kevin; Renkel, Patrick; Huber, Richard; Menz, NadjaThe threat of cybersecurity incidents is increasingly challenging for companies and employee interaction plays a crucial role in the majority of cyberattacks. In this paper, we present a mobile, scalable IT-security lab to investigate the human factor in such incidents. The lab enables study participants to experience cyberattacks in an immersive workplace environment. In order to ensure that the target group of small and medium sized company (SME) employees is reached, we have designed the mobile lab in such a way that it can be easily operated in different locations and sizes.
- KonferenzbeitragAnalysing user’s privacy preferences in smart-home environments with situational contexts(Open Identity Summit 2023, 2023) Ruff, Christopher; Benthien, Benedict; Orlowski, AlexanderDue to the increasing adoption of smart home devices and technologies, implications for privacy gain importance. In this paper, correlations between specific characteristics of people and their preferences regarding the activity status of components in smart home devices are investigated. In addition, said preferences are analysed for inherent patterns to assist people in their decisions by suggesting preferences, which often occur together. A special focus of this work is the differentiation of preferences according to situational contexts. An online survey was conducted, and the results were analysed. The results imply strong correlations within the preferences and differences in preferences across different contexts.
- KonferenzbeitragBalancing Privacy and Value Creation in the Platform Economy: The Role of Transparency and Intervenability(Open Identity Summit 2023, 2023) Astfalk, Stefanie; Schunck, Christian H.Data are essential in the platform economy to create value. Since the General Data Protection Regulation (GDPR) demands a high level of protection for personal data, it becomes challenging for small- and medium-sized businesses to provide both: data-based services and compliance to the GDPR. Therefore, the paper focuses on the privacy protection goals of transparency and intervenability to enable privacy friendly business models. To better understand how this approach supports the needs of small- and medium-sized platform providers, a qualitative interview study is conducted. Especially, the lack of legal certainty and the unclarity of how the GDPR can be implemented compliantly in practical terms is found to be a challenge. Based on the interviews, requirements are derived which a personal rights management tool enabling transparency and intervenability should fulfill such as supporting legal compliance or reducing operational complexity. In summary, small- and medium-sized platform providers see providing transparency and intervenability as a promising new approach which they are willing to deploy given the right personal rights management tool.
- KonferenzbeitragMANTRA: A Graph-based Unified Information Aggregation Foundation for Enhancing Cybersecurity Management in Critical Infrastructures(Open Identity Summit 2023, 2023) Fuxen, Philipp; Hackenberg, Rudolf; Heinl, Michael P.; Ross, Mirko; Roßnagel, Heiko; Schunck, Christian H.; Yahalom, RaphaelThe digitization of almost all sectors of life and the quickly growing complexity of interrelationships between actors in this digital world leads to a dramatically increasing attack surface regarding both direct and also indirect attacks over the supply chain. These supply chain attacks can have different characters, e.g., vulnerabilities and backdoors in hardware and software, illegitimate access by compromised service providers, or trust relationships to suppliers and customers exploited in the course of business email compromise. To address this challenge and create visibility along these supply chains, threat-related data needs to be rapidly exchanged and correlated over organizational borders. The publicly funded project MANTRA is meant to create a secure and resilient framework for real-time exchange of cyberattack patterns and automated, contextualized risk management. The novel graph-based approach provides benefits for automation regarding cybersecurity management, especially when it comes to prioriization of measures for risk reduction and during active defense against cyberattacks. In this paper, we outline MANTRA’s scope, objectives, envisioned scientific approach, and challenges.
- KonferenzbeitragA more User-Friendly Digital Wallet? User Scenarios of a Future Wallet(Open Identity Summit 2023, 2023) Krauß, Anna-Magdalena; Kostic, Sandra; Sellung, Rachelle A.Identity wallets enable the management and use of digital identities and verification documents stored in one app. Users manage their data independently and decide for themselves which data they want to disclose for identification purposes. Recent research shows that current digital wallets face many usability problems, which makes it difficult for users to grasp their concept and how to use them. This paper presents an enhanced concept of a wallet, where its functionality is presented with user scenarios that have a user centric approach. The user scenarios illustrate a variety of possible uses of the wallet. For example, the new wallet concept envisions, how data can be transferred from one wallet to another person's wallet, how data can be managed by different people in one wallet, or how only individual pieces of information from credentials can be shared to maintain greater privacy for users.
