| Summary: | We leverage on authenticated data structures to guarantee correctness and completeness of query results over encrypted data. Our contribution is in bridging two independent lines of work (searchable encryption, and provable data possession) resulting in a general purpose technique, which does so without increasing the client storage overhead, while only a small token and a data structure is added to the server side (in comparison to a base searchable encryption without mechanisms for determining result integrity), where the data structure can simultaneously also be used for integrity checks on the stored data. |
