User-Controlled Data Sovereignty in the Cloud
Cloud computing plays an increasing role in the IT-market. Promised scalability and flexibility attracts enterprises as well as private end users. The loss of data sovereignty is seldom addressed but nevertheless a serious threat to users. The FlexCloud research group proposes an approach that enables users to profit from public cloud scalability without losing data sovereignty. The proposed dissertation derives from the work within the research group. The goal of this paper is an architecture design of a gateway for the secure outsourcing of sensitive data.
