AB  - A novel approach proposes in this research to improve the performance of the query over encrypted database. This approach based on using hash map function to generate a unique hash value for each and every sensitive data. In this a proposed approach, there are no relationship between the hashed value and encrypted value. This method can reduce the cost of the encryption and decryption operations and improve the query performance. Results of the set of experiments show that the query performance over encrypted data reduces the response time to 25s, 51s, 34s, 61s and 31s for queries 1, 2, 3,4 and 5; respectively. The comparison with other methods are carried out when database size is ranging from 50,000 to 100,000 rows.
