Research Of Data Safty Control In MIS Under C/S Mode

For decades,the application on data becomes more and more expanding along the development of IT. From traditional MIS to current DSS and ERP/MRP,it has enhanced the efficiency of the management and production of the enterprise greatly. Accompanied the implement of this technology,the network makes the management information system popular,whereas it brings the problem of data safe transmission. And the unrelenting information leakage and network criminal set safety apart. It is an emergency mission for programmer to solve the problem.In this article some research and design upon above is done.The mathematic models of DES&RSA are described which are data encryption algorithms with higher safety factor and their strongpoint and shortcoming are compared respectively. An improved project named Combined Encryption built upon the algorithms mentioned before is put forward,valued the availability and programmed.Based on above research,the software for labor source MIS under C/S mode has been finished and applied primarily with VB6 as front-end development tools and SQL Server7 as back-end database by object-oriented approach.data safty is attained and it is put into application.
