Blockchains, Smart Contracts and Future Applications (Dagstuhl Seminar 18152)

Authors: Foteini Baldimtsi, Stefan Katzenbeisser, Volkmar Lotz, and Edgar Weippl

Published in: Dagstuhl Reports, Volume 8, Issue 4 (2018)


Abstract
This report documents the Dagstuhl seminar 18152 "Blockchains, Smart Contracts & Future Applications". While Bitcoin currently works well in practice, there are many open questions regarding the long-term perspective of blockchain technologies, for both public and private/permissioned blockchains. It is yet unclear how processes can be designed to work in predictive ways and how to embed security in the lifecycle of smart contract development and deployment. Furthermore, the distributed nature of the system needs to be considered when thinking about which groups or individuals can influence future developments. Similar to 'real-world' societies, blockchains are based on mutual recognition of conventions. Diverse academic disciplines as well as industry can and need to collaborate to advance research in blockchain and to fully understand how the technology might impact our future lives.

Privacy and Security in Smart Energy Grids (Dagstuhl Seminar 16032)

Authors: George Danezis, Stefan Katzenbeisser, Christiane Peters, and Bart Preneel

Published in: Dagstuhl Reports, Volume 6, Issue 1 (2016)


Abstract
This report documents the program and the outcomes of Dagstuhl Seminar 16032 "Privacy and Security in Smart Energy Grids". Smart electricity grids augment the electricity distribution network with modern communications and computerized control to improve efficiency, reliability, and security of electricity distribution, and more flexible production. This initiative has been greeted by consumers and utilities not only with enthusiasm but also concern. Consumers worry about their privacy. Utilities worry about the security of their assets. These outcries and reactions have triggered academics and industry to look into designing privacy friendly architectures for smart metering. The Dagstuhl Seminar 16032 brought together academic researchers as well as utility experts in order to start an open dialogue on smart grid privacy and security problems and potential solutions to support customers and utilities. A particular focus of the seminar were problems related to two timely use-cases for the smart grid, namely smart charging of electric vehicles and distribution automation.

Genomic Privacy (Dagstuhl Seminar 15431)

Authors: Jean Pierre Hubaux, Stefan Katzenbeisser, Bradley Malin, and Gene Tsudik

Published in: Dagstuhl Reports, Volume 5, Issue 10 (2016)


Abstract
This report documents the program and the outcomes of Dagstuhl Seminar 15431 "Genomic Privacy". The current rise of personalized medicine is based on increasing affordability and availability of individual genome sequencing. Impressive recent advances in genome sequencing have ushered a variety of revolutionary applications in modern healthcare and epidemiology. In particular, better understanding of the human genome as well as its relationship to diseases and response to treatments promise improvements in preventive and personalized healthcare. However, because of the human genome's highly sensitive nature, this progress raises important privacy and ethical concerns, which simply cannot be ignored. A digitized genome represents one of the most sensitive types of human (personal) identification data. Even worse, a genome contains information about its owner’s close relatives. The Dagstuhl seminar 15431 brought together computer scientists, bioinformaticians, geneticists and ethical experts to discuss the key security and privacy challenges imposed by the storage of large volumes of genetic data.

Privacy and Security in Smart Energy Grids (Dagstuhl Seminar 11511)

Authors: Stefan Katzenbeisser, Klaus Kursawe, Bart Preneel, and Ahmad-Reza Sadeghi

Published in: Dagstuhl Reports, Volume 1, Issue 12 (2012)


Abstract
The ``smart energy grid'' promises to improve the reliability and efficiency of the future energy grid by exchanging detailed usage information between the end consumers and the utilities. This application raises different questions with regard to privacy and security. For instance, detailed meter readings enable to infer detailed information on the private life of the consumers; furthermore, manipulations of meter readings open the possibility of fraud. The goal of the seminar was thus to raise awareness of the privacy and security problems associated with smart meters and bring together academic researchers as well as utility experts in order to start an open dialogue on smart grid privacy and security problems and potential solutions.
