Abstract

In this work we present MK-SEAC, a scheme that allows to perform outsourced keyword-based search queries on an encrypted document batch, with native support to multi-keyword queries, fine-grained access control on the results, and full verifiability. The scheme conceals both the query and the results from the server, and minimizes the information revealed about documents to which users do not have access. Compared to other schemes, such as SEAC by Nils Löken, MK-SEAC offers extended improved efficiency with a reduced leakage profile.
