|Title||Power Range: Forward Private Multi-Client Symmetric Searchable Encryption with Range Queries Support|
|Authors||Bakas, A. and Michalas, A.|
Symmetric Searchable Encryption (SSE) is an encryption technique that allows users to search directly over their outsourced encrypted data while preserving the privacy of both the files and the queries. In this paper, we present Power Range -- a dynamic SSE scheme (DSSE) that supports range queries in the multi-client model. We prove that our construction captures the very crucial notion of forward privacy in the sense that additions and deletions of files do not reveal any information about the content of past queries. Finally, to deal with the problem of synchronization in the multi-client model, we exploit the functionality offered by Trusted Execution Environments and Intel's SGX.
