TRUST MEASUREMENTS YELD DISTRIBUTED DECISION SUPPORT IN CLOUD COMPUTING

This paper proposes the creation of a trust model to ensure the reliable files exchange between the users of a private cloud. To validate the proposed model, a simulation environment with the tool CloudSim was used. Its use to run the simulations of the adopted scenarios allowed us to calculate the nodes (virtual machines) trust table and select those considered more reliable; identify that the metrics adopted by us directly influenced the measurement of trust in a node and verify that the trust model proposed effectively allows the selection of the most suitable machine to perform the exchange of files.
