SOA based cloud computing trust model research with a curve fitting method

This paper proposes a cloud computing trust model based-on SOA by combining the characteristics of SOA, and discusses the relation between the service and users in the cloud computing. Meanwhile, proposes a curve fitting based trust selecting and updating mechanism to ensure the authenticity and accuracy of the trust relation. Finally, verifies the rationality of the trust model in terms of the curve fitting function and mathematical experiment analysis of this trust model.
