Reputation Based Two Way Trust Model for Reliable Transactions in Grid Computing
Grids computing is a coordinated resource sharing and problem solving in any dynamic environment. Computing resources are highly heterogeneous. Grid computing and its related technologies will only be adopted by users, if they are confident that their data and privacy are secured and the system must be as scalable, robust and reliable as of their own in their places. Reliability is the probability that a process will successfully perform it's prescribed task with out failure at a given point of time. So allowing reliable transactions plays a vital role in grid computing. Reliability of any transaction increases when it passes through two way test criteria. That is the consumer is satisfied with the ability of the provider and the provider in turn is reasonably happy with and willing to provide service to the user. To achieve this kind of reliable transactions mutual trust must be established between the initiator and the provider. Trust is measured by using reputation and reputation is the collective opinion of others. This paper provides a model which will allow only reliable transactions in grid by using trust as a measure for both provider and consumer. This enhances the security in grid.
