Comparative study on encrypted database techniques

الملخص EN

Protecting data is the core of many secure systems and many users depend on a database management system (DBMS) to manage the protection.

Databases are essential to many business and government organizations, holding data that reflect the organization’s core competencies.

Database encryption refers to the use of encryption techniques to transform a plain text database into a encrypted database, thus making it unreadable to anyone except those who possess the knowledge of the encryption key(s).

Encryption is becoming the last line of defense in database management system(DBMS)security.

There is the essentiality of algorithms which are protected from intruder as well as maintain the performance of the system.

Therefore, this paper presents most of the recent works that have been conducted on encrypted database techniques and analyzes them to clarify the pros and cons points in each related work.

This paper has focused on previous studies for both symmetric and asymmetric encryption techniques.

However, they missed to show some numerical analysis that would help readers to deeply understand the difference among different techniques.
