Research On Security Mechanism And Data Interface Design Of Mail Storing And Collecting Office Automation System

This paper carries through large and embedded analyses and studies on how to build security mechanism and implement data interface in the Office Automation System. Its exploring background is a practical colligation operation Office Automation System which is explored for HeiLongJiang mail storing and collecting bureau..At the beginning of the article, there is the expatiate on needing of OAS. Along with the progress of society and the prevalence of network, it becomes the necessary request that enterprises come true the net working, well if let net working be possible, the security of information is necessary safeguard. At the same time, because the old MIS application of the enterprise depart with the office information , if abandon the old MIS and adopt the new technique platform to explore again, it is obviously not realism. So base on the LAN system, make the best use of the old information resource to build the unit's office information integration system has been the necessary selection of enterprise informationlize.Secondly, it introduces the choiceness capability of the platform of constructing OAS-Lotus/Domino, and its mail technique security performance and workflow mechanism ,then discuss the character of client/server construct.Thirdly, it discusses the designing project and functioning implement of the system. The paper introduces in detail from net top construct hardware equipment and software system function.Finally, against the technique difficulties(encrypting database encrypting documents in database encrypting the fields in document and the connecting technique with SQL database) during the system designing ,there are two parts to research in detail and depth .One the aspect of security, the author build the security system frame of bedding management based on the RSA key system. There are corresponding security limitations in physical security layer network security layer server security layer application security layer application designing elements security layer, and ensure absolute security of the whole system. While dissertate the keys management theory and RSA arithmetic in detail.One the aspect of interface, thinking about the virtue of SQL database on database technique, there are two parts :OA and MIS in the designing .Put the files of needing flow on the Notes, and put a great deal of operation report forms which need to be Statisticed on the SQL data end, using interface ability with exterior database of Lotus Notes ,through building ODBC data resource and usingprograms to pick up the correlation data on SQL end, and making the two system integrate together.The researching of OA information integration system in this paper has been applied successfully and gained well application effect, and greatly increased management level and official efficiency inside the enterprise. It has broadly engineering application foreground.
