  Data is the central asset of today's dynamically operating organization and
their business. This data is usually stored in database. A major consideration
is applied on the security of that data from the unauthorized access and
intruders. Data encryption is a strong option for security of data in database
and especially in those organizations where security risks are high. But there
is a potential disadvantage of performance degradation. When we apply
encryption on database then we should compromise between the security and
efficient query processing. The work of this paper tries to fill this gap. It
allows the users to query over the encrypted column directly without decrypting
all the records. It's improves the performance of the system. The proposed
algorithm works well in the case of range and fuzzy match queries.
