Recent Trust Models in Grid
A grid is a framework providing services to access and manage distributed hardware and software resources. A thorough authentication is required before any requested access or operation is allowed on any resource of the grid. In particular, much risk is involved when the grid is used for e-commerce where it is necessary to share resources with unknown parties. It is difficult for a resource user on the grid to identify the quality of the resource providers. Trust is one mechanism with which one can identify the quality of the resource provider. Various models are proposed in the literature on the use of trust mechanisms in grid. This paper presents a survey on various models proposed recently on trust management in grid computing.
