A comparative survey of searchable encryption schemes

With the fastest technology of modern life we always have to deal with numerous data in various way. We simultaneously store and retrieve data in database of large organization, email server, cloud server etc. Due to this process both the owner and user need security of the data and therefore the data is encrypted before use. Because of this encryption process, some problem arises at the time of searching and retrieving of particular data. Searchable encryption is a scheme which assures the owner and user a secure and efficient searching operation. There has been growing interest in searchable encryption in both academics and industry. Over the years different type of construction of searchable encryption have been introduced. In some of them, researchers have emphasize on the efficiency of searchable encryption technique and somewhere security and privacy have got more attention. In this paper, a comparative survey has done on various technique of searchable encryption.
