摘要：In this environment of multi cloud providers, the assurances are not enough for the cloud users to selectthe trustworthy cloud service providers. Trust is one of the most concerned obstacles for the adoption and growth ofcloud computing. Determining the credibility of trust feedbacks is mostly neglected. In this paper, we present theimportance of trust management in cloud environments. It also describes the feedback based trust issues where trustcalculation is done through feedback of cloud users. It is important to identify the feedback based attacks because lesssubmission of fake feedbacks can also compromise the whole trustworthiness of service provider. Also, we propose amethod for the trusted service using three topological metrics, including in-degree, out-degree and reputation measures.The proposed method has been evaluated in different challenging situations where obtained results show the increase inaccuracy of proposed method using the advice of trusted service providers.
