A New Trust Management Architecture for Cloud Computing Environment

Cloud Computing is a new emerging computational model. Cloud features like rapid elasticity, pay per use, location independence, on demand infrastructure providing capability and everywhere network access are attracting both Cloud consumers and providers. But there are several concerns relating to security, privacy and trust that hinders the adoption of cloud in spite of several beneficial features. In this paper, we present a trust management architecture which consist of a Cloud Service Registry and Discovery which serves as cloud providers' registry and lists their respective trust values, a Trust Calculator that calculates CSP's trust based on feedbacks of two parameters namely SLA and QoS. A Dynamic Trust Monitor keeps watch on the deviating trust values with time and transactions.
