Understanding Cyberprivacy : Context, Concept, and Issues

Cyberprivacy has become one of the most worrisome issues in the age of digitalization, as data breaches have increased at an alarming rate, and the development of technology has changed privacy norms themselves. Thus, maintaining cyberprivacy is important for both academia and practitioners. However, the literature on cyberprivacy is fragmented, since the topic is multidisciplinary and often confused with cybersecurity and data privacy. In this study, we seek to understand cyberprivacy by conducting a comprehensive literature review and analyzing 79 selected articles on the topic between 2008 and 2021. Our analysis shows that there are eight contexts associated with cyberprivacy. We proposed concepts on cyberprivacy from different views and highlighted four issues related to cyberprivacy for future consideration. Taken together, the knowledge on cyberprivacy, its challenges and its practices does not seem to accumulate. Consequently, there is a need for more targeted research on the topic to cover different contexts.©2022 The Association for Information Systems (AIS), Friedrich-Alexander-Universität, International Conference on Wirtschaftsinformatik.fi=vertaisarvioitu|en=peerReviewed

On security and privacy of consensus-based protocols in blockchain and smart grid

In recent times, distributed consensus protocols have received widespread attention in the area of blockchain and smart grid. Consensus algorithms aim to solve an agreement problem among a set of nodes in a distributed environment. Participants in a blockchain use consensus algorithms to agree on data blocks containing an ordered set of transactions. Similarly, agents in the smart grid employ consensus to agree on specific values (e.g., energy output, market-clearing price, control parameters) in distributed energy management protocols. This thesis focuses on the security and privacy aspects of a few popular consensus-based protocols in blockchain and smart grid. In the blockchain area, we analyze the consensus protocol of one of the most popular payment systems: Ripple. We show how the parameters chosen by the Ripple designers do not prevent the occurrence of forks in the system. Furthermore, we provide the conditions to prevent any fork in the Ripple network. In the smart grid area, we discuss the privacy issues in the Economic Dispatch (ED) optimization problem and some of its recent solutions using distributed consensus-based approaches. We analyze two state of the art consensus-based ED protocols from Yang et al. (2013) and Binetti et al. (2014). We show how these protocols leak private information about the participants. We propose privacy-preserving versions of these consensus-based ED protocols. In some cases, we also improve upon the communication cost
