Challenges for trustworthy (multi-)Cloud-based services in the Digital Single Market

The future Digital Single Market (DSM) poses a number of research challenges for future years. Particularly, the DSM Initiative #14 on “Free flow of data” directly impacts on a number of security and privacy issues on (multi-)cloud-based services and cloud services. The objective of this White paper is to develop an initial map of challenges identified by the DPSP Cluster projects related to the DSM Initiative #14 topics at the right level of abstraction that could be reused by the EC and policy makers. The map includes collection of the challenges more relevant for the next Horizon 2020 Work Programme 2018-2020.
