摘要
Abstract
Searchable symmetric encryption was recognized as an efficient method for searching within encrypted data.The IEX scheme was the first to achieve sublinear search complexity while supporting Boolean queries;how-ever,it was found to incur high server storage overhead.To reduce the storage cost on the server side,a data organi-zation method based on triangular matrices was proposed.This method was shown to reduce the data volume of pairwise keyword-document intersections by approximately 50%.Based on the aforementioned data organization method,an improved scheme named IEX-RS was further proposed.Experimental results demonstrate that the IEX-RS scheme significantly reduces server storage overhead by 49%,while search performance equivalent to that of the original IEX scheme is maintained.关键词
