Abstract :
Conventional Grid security mechanisms for authentication and authorization are too rigid and they lack the ability to determine how "trustworthy" the result obtained from a specific provider is likely to be. This inefficiency can be mitigated through proper trust management mechanisms. In our invention, a trust management system has been developed that evaluates the trust value of various resource providers across the grid environment. Different classes of parameters that affects trustworthy of a resource providers have been considered for estimating the trust. We attempt to enhance the capability of a conventional Grid Metascheduler by integrating trust management system in it. The integration of trust management system with a grid metascheduler act as a Trust Resource Broker that discovers suitable resources matches the job requirements and selects single resource based on their trust value. We further proposes a four layered grid architecture that performs trust based scheduling of the computational resources by validating the trust of the resource providers.
