| The rapid development of e-commerce has brought huge benefits, it also brings the transaction process user account stolen,business data is cut, data is tampered, business operations is denied, the operating time is imprecised and other security issues. Textile quota bidding system is applied to a textile quota bidding management system. It is based on C/S mode, all information and data are transmitted via the Internet, so security is a seriously problem.PKI technology is introducing to this Textile quota bidding system to solve the security problem, Combined with business of the Textile quota bidding system and existing PKI/CA system, with the design goal allowing both PKI/CA security services provided with the normal use of the Textile quota bidding system, enhancing PKI/CA systems provide similar services outside the ability, but also to maintain the relative independence, Completion of the final transformation of these two systems.This paper first analyzes the background of the system development, Then the development process used to PKI technology, developing technology, SSH framework technology and webService techniques were introduced, and about the reasons for selection of each technology; describes the overview of the existing two systems and two systems for the analysis of their transformation; and the use of UML for system design, the use of Axure RP for the system prototype design; The use of SSH, webService and other technology realize the transformation PKI/CA system, Textile quota bidding system with OCSP, TSA, LDAP, CA systems is of integration and other applications; using the tools tests the function and performance of the system; Finally, the system summarizes the work and prospects for future applications.The system has advantages of easy to manage, easy to maintain, fast integration, flexibility and scalability, etc., it has also meet the security requirements of Textile quota bidding system, improved the PKI/CA capacity to provide services outside the system, reduced the coupling between the two systems and provides a solution for the PKI/CA system in other applications of the user business system. |
