Research on the searchable encryption

Abstract

Searchable encryption has been recognized as a promising method to achieve the secure cloud search.According to the types of encryption keys,searchable encryption can be divided into searchable public-key and symmetric-key encryptions.The existing and well-known schemes of those two kinds of encryptions,their limitations,and the corresponding solutions were introduced.Specifically,two works under the condition of high security were introduced:one was to reduce the search complexity of searchable public-key encryption; the other one was to achieve the physical deletion of searchable symmetric-key ciphertexts.
