Critical business data in databases is an attractive target for attack. Therefore, ensuring the confidentiality, privacy and integrity of data is a major issue for the security of database systems. High secure data in databases is protected by encryption. When the data is encrypted, query performance decreases. In this paper, the authors propose a new mechanism to query the encrypted data beside make a tradeoff between the performance and the security. Their mechanism will work over many data-types. They implement their paper as a layer above the DBMS; this makes their method compatible with any DBMS. Their method based on replacing the select conditions on the encrypted data with another condition which is faster.
