Abstract
The recent developments in cloud computing technology show an increase in security, privacy and trust related problems, in many ways, which haven't been predicted by the ones who have been designing clouding environments. Among them, the users trust problem and cloud computing resources secure access warranty have deserved special attention. At this study, it will be presented a review on the concepts of cloud computing, trust and reputation, and some open questions related to trust and security in cloud computing environments will be discussed. Computing systems trust and reputation representation have been widely discussed and applied in a lot of information technology scenarios, becoming subject of scientific researches both from a theoretical and practical point of view. This paper proposes the development of a high level trust model to ensure a reliable files exchange among users in a private cloud, as well as the calculation process of trust among these users, according to the metrics previously established.
