Research of Database Encryption Technology and Its Application

With the continuous improvement of the national level of information technology, especially the rapid development of Internet technology, IT database system is more and more widely. However, the database system data storage and extensive sharing of features, making the database system security issues become very prominent. At present, only through the database management system's own security mechanism is also difficult to completely solve their security challenges. So the database encryption technology research has a considerable practical significance, it will modern cryptography principles applied to the database system, and further improve the database security system, effectively guarding the DBMS super administrator privileges too high risk, can be effective Against the invaders in the application layer of the attack, so as to ensure the safe operation of information systems.
