Design And Implementation Of Security Classification Identification Generation And Management System

In order to achieve the security classification identifies of electronic documents in the e-government network environment with the flow control, tracking and auditing, the relevant security companies have developed security classification identification generation and management system (hereinafter referred to as "security classification identification system"). Security classification identification system has a wide range of application development, such as used with e-government network environment OA system, mail system, PKI/CA authentication system and other applications closely integrated and nested so that the application system achieve security classification identification feature. Analysis and research the function definition of security classification identification system, is a key role to achieve reservation secret of electronic documents, officially secret and other business processes. With study,.NET architectures as one of the current mainstream programming system which can provide the basis for the security classification identification system development environment, has to achieve C/S system architecture show.This thesis mainly studies the.NET architectures, combined with the user's actual needs, complete the detailed design of the security classification identification system modules, so as to achieve add security classification identification to electronic documents.The primary works in this thesis are presented as follows:1)The main functions of the security classification identification system are summarized, the requirements of the actual users are researched, the requirement analysis of the system is completed and the corresponding solutions are put forward;2)The key technologies used in the security classification identification system, such as.NET technology, AES algorithm, ActiveX control technology and so on in C/ S application mode, are introduced in detail;3)This thesis discusses the functional requirements, performance requirements, system architecture, system modules and business processes of the system, and completes the overall design of the security classification identification system;4)The detailed design and implementation of the system from the aspects of the function modules of the management system, the function modules of the client, the design and implementation of the relational database and the design and realization of the security classification identification system are expounded;5)After the completion of the security classification identification system design, the author verifies the function and performance of the system and confirms whether the system function meets the actual demand and whether the performance is stable or not.In this thesis, the design and implementation of security classification identification system has been put into use in the country of a unit, using the results reflect good.After the security classification identification system deploy in the practical application of the e-government network environment, reserve implements electronic document secret, officially secret, documents issued by other important business processes, the electronic documents marked secret classification identification life cycle provides technical support.
