Trusted services identification in the cloud environment using thetopological metrics


The trust and reputation in cloud computing are always made only if enough services and expectations are attained. Also, it is arental for the exploitation of information technology assets and resources. Therefore, this paper evaluates the reputation values andidentifies the trusted services in the Cloud environments. The reputation value is evaluated using three parameters includingaccessibility, dependability, and ability. Also, we propose a method for the trusted service using three topological metrics, includingin-degree, out-degree and reputation measures. The proposed method has been evaluated in different challenging situations wherethe obtained results show that the accuracy of the proposed method using the advice of the trusted service providers is increased.
