摘要
Abstract
Searchable encryption has been widely used in cloud storage.Traditional searchable encryption scheme only supports precise matching,so decreases the efficiency of the scheme.We construct the index with the help of edit distance and trie to solve searching problem caused by spell mistakes.Compared with traditional fuzzy keyword search scheme,this scheme increases index size,but decreases search time,improves the dynamic performance,and can solve the problem of spell mistakes effectively.In addition,this scheme reduces the users' overhead generating search token and the potential leaking information,so it improves system security.关键词
