A Status Authentication Mechanism in Grid Environment

The grid is an heterogeneous distributed environment, it has many new characteristics that are different with the traditional internet, for example, it have many users and resources. These characteristics have decided complexity of the grid safety mechanism. Thus security is an important element of the practical of grid computing technology. In paper, we described a hybrid model of authentication against centralized, hierarchical structure, other traditional forms of authentication features and combining grid security needs. Compare and analyzed the hybrid model authentication mechanisms, performance, and the implement methods of these models, and verified the safety and effectiveness of the hybrid mode. It described the design process of hybrid mode in detail . Given the specific systems certification flow and the performance analysis of application , it is great significance for grid security and management.
