Search, Find and Resolve: Towards a Taxonomy for Searchable Encryption Schemes
Ines Kramer, Silvia Schmidt, Mathias Tausig, Manuel Koschuch · 2019
Searchable Encryption (SE) schemes are a promising solution to the problem of outsourcing one’s data to a cloud provider in a secure way, while still retaining the ability to search for and easily retrieve specific documents. A multitude of different schemes have been proposed and designed, yet in general they still lack usability/applicability for a specific use case or proper security analysis in order to be widely implemented and used. To address this issue we started a project to determine which SE schemes fit certain use cases - mainly focusing on usability. We examined nearly 400 papers on SE schemes from the last 13 years and extracted categorization domains for SE schemes. Furthermore we took a time-based look at these domains and tried to identify future trends in SE technologies. In this position paper we introduce our methodology and give a short overview of our current work-in-progress.
