File Exchange in a Private Cloud Supported by a Trust Model

Abstract

Cloud computing is being progressively adopted in different business scenarios in order to obtain flexible and reliable computing environments, with several supporting solutions available in the market. Computing systems trust representation have been widely discussed and applied in a lot of information technology scenarios, becoming subject of scientific researches. This paper proposes the development of a trust model to ensure a reliable files exchange among nodes in a private cloud, as well as the calculation process of trust among them, according to the established metrics. The simulation result using CloudSim framework shows the effectiveness of the model in selecting more reliable node in private cloud.
