Abstract: It is an effective security measure to encrypt the key data in the database. An effective realization program is put forward on the basis of in-dept research. In this program, the encrypted database can be a variety of common database compliant with SQL standard and the encryption size is a table field, moreover, the key management has a high degree of flexibility. In order to verify the correctness and feasibility of this program, a simulation system of database encryption system is realized. The data from the testing simulation system reveals that the database encryption system design program is feasible.
