Efficient Strong Privacy-Preserving Conjunctive Keyword Search Over Encrypted Cloud Data. (arXiv:2203.13662v1 [cs.CR])

Searchable symmetric encryption (SSE) supports keyword search over outsourced
symmetrically encrypted data. Dynamic searchable symmetric encryption (DSSE), a
variant of SSE, further enables data updating. Most prior DSSE works primarily
focus on single keyword search, and some have later expanded to support
conjunctive keyword search. These works on conjunctive DSSE primarily consider
forward and backward privacy. Ideally, the server should only learn the result
sets related to all the keywords in the conjunction. However, existing schemes
suffer from keyword pair …
