Abstract


The increasing maturity of cloud computing promotes the development of searchable encryption technologies. In order to improve the retrieval efficiency, a Multi-keyword Searchable encryption technology based on the B+ tree is proposed in this paper. Establish indexes and retrieval trapdoor by using the space vector model and sort retrieved results according to the relevance score and the keyword matching. Experiments are carried out on real data sets, and the results show that the proposed scheme has high retrieval efficiency.

Keywords
