An Adaptive Trust Model for Software Services in Hybrid Cloud Environment
The objective of the research work is to propose an adaptive trust model applicable for software services deployed in cloud environment. In the earlier security modeling of cloud based applications, the trust among various services are evaluated either based on Bayesian or fuzzy approaches which are not formally verified before composition. The reputations of the constituent domain specific services are evaluated to determine the overall trust of the demanded service assuming other infrastructure and platform services. The trust relation is migrated between various virtual services in the case of emergent termination or cancellation of the customer demand.
