The Research And Application Of A Grid Certificate System

Grid security is the kernel of Grid computations. There is not an uniform international standard of grid security now, Some international organizations, such as GGF( Global Grid Forum) OMG( Object Management Group) W3C( World Wide Web Consortium) and Globus Grid Forum, are instituting the standards of grid security by themselves and contesting the right to became the international standard.The Grid Security is closely related to the immediate interests of our country, society and subscribers, which only can be developed by technology power of our own. Among these, Client Access Authentication Technology ensures encrypting communications participator's identification against hacker's fabricating status, malicious bugging and distorting, and plays an important role in protecting the security of Grid computations communication and recourses accessing.This paper focuses on the Grid Security and it elaborates on the application of security certificate technology. We will list the threaten on the Grid computations, then we analyze the grid security structure, to state the four models. We will introduce the principles of the models, and introduce how to create a safety Certificate Authority (CA) System. And in this article, a new model will be created and a new certificate authority system will be established.
