Based On Agent Grid Portal Authentication And Authorization Mechanisms

Science is the first productive force, this is the truth during the development of mankind. With the progress of the society, science and technology are also advancing. The Grid is a new kind of network technology, and is the next important milestone after Internet. This paper will first introduce the concept of grid to you in a reader's way, and then introduce the connotation of the authentication and authorization of the Grid to you in a developer's way.In this paper, we first analyze the deficiency of GSI, and then give out three new theory: authentication path optimization base on CA; Multi fault-tolerant key base on multi credential; The trustworthy credential authentication base on blind signature. After that, we use a new method RBAC in our authorization framework, and we also apply them into the Grid environment. After we give out our framework, the paper proves some relative theory and explains with graphics and data. In the last part of the paper, part of the source code and results are included, together with the future work.
