Dynamics of trust in Clouds — Challenges and research agenda

This position paper focuses on deriving some of the challenges for trust establishment in Cloud Computing. We start by providing a conceptual model of Cloud infrastructure, and then discuss the dynamic nature of Cloud based on the provided model. We identify that the dynamic nature of a Cloud infrastructure is essential for its desirable properties (e.g. elasticity, resilience, availability, and reliability), but such dynamism results in novel challenges in Cloud context. Our contribution is identifying the effects of this dynamism on trust relationships, identifying the main challenges resulting from these effects and derive our research agenda.
