Towards Efficient Privacy-enhancing Protocols for Highly Distributed Systems

Abstract

In the current state of the World Wide Web, both the ownership and control over data of highly available systems also becomes distributed and sometimes even decentralized. From a business perspective, combining this data as part of partnerships can lead to new business opportunities; however, this also introduces security and privacy issues. More specifically, additional research is required regarding efficient and privacy-enhancing protocols. Therefore, as part of this doctoral study, we dive into existing decentralized access control solutions and secure multi-party operations. The ultimate goal of this study is to adjust the state-of-the-art solutions for decentralized access control to be used for these highly available systems. Further, we would also like to address the multi-party operations to impose additional privacy constraints on the corresponding data.
