WI2023 – Track: Distributed Trust, Security & Privacy

Track Description

While until recently, questions relating to trust, security, and privacy were still dominated by decades-old encryption techniques or data collection, especially by platform operators, a number of technologies have been developed in recent years that not only enable new applications but are already being used worldwide.

First and foremost, distributed ledger technologies (DLT, Blockchain) gained importance as a new type of distributed system for consensus building. With the help of DLT, transactions (and other data) are stored in an immutable and verifiable manner. A central authority as a “trusted third party” is not required for this but is replaced by trust in the technology and developed algorithms. However, the transparency and immutability of a distributed ledger also pose immediate data protection challenges.

Beyond DLT, other technologies also ensure security and data protection in distributed systems. Digital identities, verifiable credentials, zero-knowledge proofs, federated learning, and differential privacy are particularly worth mentioning.

Applications of the technologies mentioned stretch far: DLT is used for cross-organizational data exchange all the way to process management. Smart contracts have also been used to create fully autonomous organizations (Decentralized Autonomous Organizations, DAO), now transforming into entire industries (e.g., Decentralized Finance, DeFi), some of which already have billions of dollars tied up in them. Digital identity proofs are provided by open source projects or private providers and discussed by governments worldwide. Application areas for decentralized digital identities for individuals and machines range from public administration and the healthcare industry to the energy industry and electric cars.

In this track, we want to address applications, effects, challenges, and opportunities of the mentioned technologies in the economy and society in the context of Trust, Security & Privacy. Therefore, we invite the submission of innovative and relevant empirical (qualitative and quantitative) studies and design-oriented research papers and conceptual/theoretical contributions.
