Trust based interoperability security protocol for grid and Cloud computing

Grid and cloud computing is a kind of important information technology which enables resource sharing globally to solve the large scale problem. Security plays very important role in any internet system, specifically in Grid and Cloud computing system. Since all the resources are shared in grid computing system, trust relationship is very crucial. Different domains have different policies in rendering their resources. Cloud Security combines parallel processing, grid computing, the judgment of unknown viruses and other emerging technologies and concepts, through the mass of the network client, detects status of all abnormal behavior and obtains the latest information of Trojans, viruses and other undesirable programs, sends information to the server for automatic analysis and processing, distributes solutions to each client to solve insecurity. This paper proposes an interoperability security protocol for both grid and cloud computing. There is no need for separate security protocol for grid and cloud computing environments.
