The Design And Implementation Of The Digital Certificate Authority System

With the continuous promotion and application of our country’s network and Internet technology especially with the continuous promotion in the field of e-commerce and e-government internet fraud and the crime of the network is increasing network security has become a social problem have to face.in order to our country E-government and e-commerce application escort PKI digital certificate system based on recognition technology has been widely applied in the field of network security. In this paper based on the existing network security application,through the combination of network application system application and business requirements design and implement a digital certificate authority system for network security industry.Firstly, on the basis of discussing the background, system development status at home and abroad the development platform and the technology analysis of the system development goal, functional requirements and performance requirements and system use case diagram and flow chart method is described in detail.Secondly, based on the analysis of demand, we conducted the system technical architecture and functional structure. technical architecture aspects of system scalability, maintenance and performance problems, by now more popular J2EE technology and B/S framework, function to discuss the function of each part of the system and describes the function of dynamic process.Third, on the basis of the summary design, we implement every module of the system detailed design. We through the detailed description of each module of the system, given the function of each function point parameter name, composition and function description of the structure, and has carried on the detailed elaboration through the graph, table way.Forth, on the basis of the detailed design of each module, coding and testing are briefly introduced, given the overall effect after the realization of the system and each part of pictures, and gives more representative of the function, for example the CA certificate issued, storage and certificate issued by the user information code, and gives the test method, process and conclusion.Finally, this paper summarizes the realization of the system, the system presents some not yet perfect function and shortcomings, and put forward the opinions and suggestions for further improvement of the system.In summary, based on the analysis of the basic premise requirement of industry of domain knowledge and user below, combined with the existing technology to design and implement a digital certificate authentication system.
