Two-stage index-based central keyword-ranked searches over encrypted cloud data

【摘要】 Dear editor,Searchable encryption[1]technology is an effective method for solving ciphertext keyword searches in cloud environments.In searchable encryption schemes,a variety of index structures are used to improve search efficiency.For example,Xia et al.[2]designed a dynamic searchable encryption scheme using a keyword-balanced binary tree,and the search efficiency was high.Wang et al.[3]proposed a multi-keyword search scheme based on an inverted index,which also improved search efficiency.
