The Design Of Pki/ca Certification System In Digital Enterprises

PKI (Public Key Infrastructure) is a universal security infrastructure which is implement and providing security services with public-key concepts and techniques. It is the development security infrastructure for carrying out electronic commerce. electronie government. online banking. The research has an important promoted role on the development of the internet.J2EE platform which centers on Java is internationa standards core technology by SUN modern distributed object technology. which dominates in this field. Construction of PKI/CA system based on JAVA platform is the more popular technologyIt needs to carry out the design of attestation system organization unitedly according to the company's condition when planning and building digitization enterprise PKI/CA attestation.There are kinds of CA system structure, but now company often has subsidiary company. which is managed by parent company directly.In order to resolving the problem of identity authentication when subsidiary company access the inside network and the communication between consumers who belong to different regions. the design adopts two layer of structure system:Be CA and two stage CA. which makes svstem have the fine dilation basis and combins with the cognition and current international to attestation system.The project focused on study of existing international standards of PKI/CA. which suggested OODM for PKI/CA based on JAVA platform. This design will help improve system stability, security and cross-platform capabilities and achieving the three core services of PKI surpportment:authentication, confidentiality integrity.The project led by raising, analyzing and solving problems, which resorted to combining of theory and experiment. It aim at requirements of enterprise for PKI/CA System, and establishing the appropriate trust model, building PKI/CA architecture. designing overall system frame. constructing. PKI/CA certification system for a modern enterprise for the digital office systems to provide safe and effective protection, which enhances the competitiveness of enterprises and security of enterprise data and the promotion of e-business...
