Abstract

To deal with database security of Management Information System (MIS), a database encryption solution is designed and implemented. Analyzing the relation of database openness and security in the traditional model of MIS, the paper constructs an improved security model of MIS. Based on database encryption theory, a multilevel cipher solution of application system is implemented in SQL Server 2005. Several experiments are carried out to compare the time spending of data manipulation based on some encryption algorithms in database. The result shows that the symmetric encryption increases the time cost about 1/3 while the asymmetric encryption increases much more. The solution is effective if it is applied to sensible data.
