Description
Summary:Now a days, many organizations as well as individuals prefer to store their data in cloud storage servers. Storing sensitive data in untrusted cloud storage server always leads to concerns about its confidentiality. In order to provide data confidentiality, encryption technique is used. To protect the sensitive information like emails and health records and, to reduce the security risks, cloud tenants encrypt the information before storing the date in the cloud. Encryption scrambles the plaintext data. But, searching for a keyword in an encrypted file is not as easy as searching in a plain text file. So, over the years many searchable encryption schemes have been proposed. Searchable encryption enables users to perform search on encrypted data. In this paper we compare the performance of index based searchable encryption schemes.
