Abstract

Over the past few years, trust management has been one of the hot topics especially in the area of cloud computing. Well-known benefits resulting from cloud computing adoption, several issues have emerged during its evolution: most of them relate to security, privacy and trust management. In particular, its proliferation has placed even more attention to trust management, representing one of the key challenges in the adoption of cloud computing technologies. This paper proposes a survey of existing trust management models addressing collaboration agreements in cloud computing scenarios. Main limitations of current approaches are outlined and possible improvements are traced, as well as a future research path.
