Establishing and Evaluating Trust in a Grid Environment

The migration of processing of computational jobs from centralized systems to open distributed systems have resulted in many communication channels and transactions. These crucial and confidential jobs span a range of domains and organizations, not all of which can be trusted to the same extent. Inconsistencies in current trust relationships highlight the need for a flexible, general-purpose trust management system. In this paper, we have proposed a Trust Model for establishing and evaluating trust in Grid environments. The proposed Trust model computes reputation and trustworthiness of the transacting domain on the basis of number of past transactions and rated feedback score.
