In cloud computing, due to large number of data users and documents, it is crucial for the search service to allow multi-keyword query and provide result similarity ranking to meet the effective data retrieval need. The searchable symmetric encryption focuses on single keyword search or Boolean keyword search, and rarely differentiates the search results. This leads to a few issues like single-keyword search without ranking, Boolean-keyword search without ranking, single-keyword search with ranking. The authors define and solve the challenging problem of privacy preserving Multi-keyword Ranked Search over Encrypted cloud data (MRSE) by proposing an efficient and more secure algorithm.
