Research Of Grid Safety Management Certificate Based On Globus Using Java And Openssl

In the grid computing environment, a variety of resources are dynamic connection to internert, and different grid nodes between communication over the Internet to complete, and grid computing environment in all main can dynamically join or withdraw from the grid in the virtual organization, because of grid computing environment dynamic principal features to make its safety requirements more complex one step. Therefore, the grid security is the underlying of a grid computing environment.This article first aggregate modern grid security, which focus on analysis Globus project in the Grid security infrastructure GSI, thereby acquire the Grid security technologies. And in conjunction with the themodern network in CA management, using Java and OpenSSL design a based on Globus grid security certificate management system. Security certificate management system basing on Globus includes the three major parts: registration authority, certification authority, the database server. The system function is divided into seven modules: user register module, user check module, certificate authority module, certificate revocation module, certificate management module, certificate inquiry module, download module. The design and realization of each module have been explained briefly at the same time. This paper focuses on the design of the grid security certification center. Firstly, it analyses and verifies the OpenSSL Security certification process. Secondly, in conjunction with the modern network in the CA security authentication management and Java, the paper designes the grid security certification management system. This system applies to the small grid environment, providinng strong support for the grid, you can provide users with client to manage its own grid certification.
