Trust plays an important role in all commercial grid and cloud environments. It is the estimation of competence of a resource provider in completing a task based on reliability, security, capability and availability in the context of distributed environment. It enables users to select the best resources in the heterogeneous grid and cloud infrastructure. This paper introduces a novel trust model to evaluate the grid and cloud resources by means of resource broker. The resource broker chooses appropriate grid/cloud resource in heterogeneous environment based on the requirements of user. Our proposed trust management system is implemented with Kerberos authentication and PERMIS (privilege and role management infrastructure standard) authorization to enhance the trust of the broker itself. The proposed trust enhanced resource broker evaluates the trust value of the resources based on the identity as well as behavioral trust. The proposed model considers metrics suitable for both grid and cloud resources. The results of the experiments show that the proposed model selects the dependable and reliable resources in grid and cloud environment.
