Cloud computing and trust evaluation: A systematic literature review of the state-of-the-art mechanisms

Abstract Cloud computing is a model to enable the convenient access to the network request for sharing the groups of configurable calculating resources. In this environment, confidences are insufficient for the customers to identify the trustworthy cloud service providers. Therefore, in this system, an important challenge is assessing the trustworthiness to enable the users for choosing the trustworthy resources in the cloud infrastructure. However, in the cloud environments, despite the significance of the trust mechanisms and methods, the comprehensive and systematic research and study about the background of the trust evaluation methods between the cloud providers is rare. Hence, in this paper, we analyzed the trust evaluation state of the art mechanisms which are used in the cloud environment so far. Also, we analyzed and compared them in terms of integrity, security, reliability, dependability, safety, dynamicity, confidentiality, scalability, and giving a suggestion for some future research. Also, this article displays a systematic literature review (SLR) on the trust evaluation mechanisms in the cloud environments up to the end of March 2017. We identified 224 articles, which are reduced to 28 primary ones through our article selection process. By presenting the state-of-the-art information and the challenges issues, this survey will directly support academics, researchers, and professionals in their understanding of changes in the trust evaluation mechanisms in the cloud environments.
