The Secure Architecture Of Grid

With in-depth research, the domain of grid applications is no longer confined only to the computation of science and engineering, but gradually extends to business and industry. The extended domain arise a key problem that is how to implement the grid security.By the research for current technique of grid and secure, and integrating with Web Service which is gradually mature, this paper presents a grid secure architecture based on Open Grid Service Architecture (OGSA). First, this paper analyzes the characteristic and framework of grid and web service. Second, it discusses the public key infrastructure (PKI) and its corresponding techniques, and has PKI as the solutions for the basic grid secure problems. Then, based on PKI, it presents many methods and techniques to solve the diverse of much complex secure problems, and uses the concept and secure techniques of web service to construct a secure framework based on Grid Service. Final, it discusses three grid resource access control models, and these models provide theoretical reference for the implementation of different access control policy.By these discussion and research, this paper presents a full grid secure solutions from theory to technique. It is a reference and direction for research and development of grid secure technology in the future.
