Authentication Mechanism Study in Grid Based on Virtual Organization and Mobile Agent
基于虚拟组织和移动代理的网格认证机制研究

Authentication is an important aspect of grid security. In grid,the basic scenes of authentication include certificate and certificate chain,dentity authentication and session authentication. We can regard the VO(virtual orga- nization) as the basic management unit of grid,and the MA (mobile agent) as an interactive means of nodes in grid thesis. The main content of the thesis is to introduce the basic content of authentication in grid to the grid based on VO and MA. Authentication Scenes of a grid based on VO include that users logging on VO,obtaining Tesources in VO,and obtaining resources beyond VO. Authentication Scenes of a grid based on MA include interaction of a MA and MAP(mobile agent platform),interaction of a MA and MA,migration of a MA.
