The Research And Design Of Security Architecture For Grid

Grid is a rising technology developed in recent years, it becomes an increasingly important field of research. Grid security issues is a central one in grid computing, the researches and analysis for grid security issues are emergent. Because of a number of characteristics of grid environment, the grid computing concerns more security problems than any other common problems,and a lot of new security problems have appeared in the grid environment .So the traditional technology of network security can not solve the problems of grid security well, so the research of grid security has become a very important, complex and tough job.Here first introduced grid technology and the concept and demand of grid security, then in-depth analysed two typical grid security solutions---the Globus security infrastructure and grid security infrastructure based on the OGSA, and then explored security certificate models for grid in detail, on the basis of grid relationship of trust model , ingenuity to make a certificate mechanism for grid of local user and the web service based grid cross-system certificate models; Explored security access control model for grid in details ,ingenuity to make a role based access control for grid environment and MPBAC (Multi-Policy-Based Access Control) in complex grid environment , the role based access control for grid environment applies role based access control to grid environment well; MPBAC models not only achieved independent autonomy among the different domains, security strategy of each domain but also is taken into consideration...
