Design And Implementation Of Wireless Certification Center

Public Key Infrastructure provides the security for the Internet E-business and information exchange. By the development of wireless telecommunication technology, the mobile E-business has increased rapidly, therefore correspond secure means are great needed. The WPKI has become the hotspot of the secure research realm.In this paper, a CA model named Wireless Certification Authority(WCA) is proposed. This model presents the design and implementation of a whole solution for CA. WCA is a trusted third authority with responsibility for issuing and managing digital certificates. Specifically, the feature of this system are as follows: 1) WCA provides the complete functional performance, and presents the full solution of root CA which centralize the user's private key and public key. 2) WCA keeps to the international standards and has entire intellectual property. In WCA, the architecture, the service and the system management strictly keep to the PKI standards, and act according to the prescripts of the national secure department. 3) In WCA, CA subsystem is established. It includes the several major functionalities: private key generating, certificate issuing, certificate publishing, certification revoking and CRL publishing, etc. 4) WCA picks the control of connection access and management of right, so WCA system fully ensured that legality when users access data. 5) In WCA, all operations of managers are recorded in system log, and ensure authoritativeness, accountability, integrity of the log. 6) The system files of WCA are encrypted with high strength algorithm, which breaks through the bound of foreign export. This also can prevent the inside attack from system and unauthorized download. 7) WCA system offers managers a friendly and facility operating interface. With this managerial system, manager can expediently manipulate all of WCA system. In a word, WCA system with entire intellectual property can be generally used in finance industry, negotiable securities, telecommunications, military, government, education, and website(ISP/ICP/ASP), and enterprise networks, etc. WCA can act as an optimal solution to build Certification Authority.
