Abstract: In order to solve the problem of high time-complexity and low efficiency of keyword search of searchable encryption scheme caused by large security index file in large data set, a scheme of Boolean symmetric searchable encryption in very-large databases (BSSEVD) was proposed. The storage structure of security index was optimized by using three-layer indirect addressing block storage, and the leakage problem caused by multi keyword Boolean search was solved by adding keyword intersection security indexes. Based on this scheme, a prototype system of searchable encryption scheme is designed and implemented, which mainly includes three modules: file preprocessing module, initialization module and keyword search module. The performance of the system was analyzed by experiments, and the experimental result showed that calculation efficiency of the scheme is significantly improved.
