Multi-level Trust Agreement in Cloud Environment

Abstract

Cloud computing introduced a new paradigm in the field of information technology by enabling the user with computing resources over the internet at any time and everywhere. These resources are scalable in nature as per the user requirement, which has reduced the cost of resource purchase and setup management. These resources also require the high consideration in terms of privacy and trust, as user data is stored and manage over the internet by an external third party, external third party. Handling the trust of different entities over the cloud environment is a challenging task because of dynamic nature of trust and cloud computing, which cannot be defined in any written argument. In this proposed work, we present a hierarchal level trust model to encourage the cloud users towards usage of cloud environment in collaboration of artificial bee colony (ABC) algorithm. Usage of ABC help in searching the various cloud service provider for the same service and find the best among them having high calculated trust value or recommendation by other user in their feedback. This paper considers both the criteria for establishing the trust i.e., direct or recommendation trust. The experimental work also convey that the proposed work has higher accuracy in trust formation, success rate and prevention of any malicious attack.
