Trust Model to Enhance Security of Cloud Computing

Trust is one of the most important means to improve security and enable interoperability of current heterogeneous independent cloud platforms. Trust is a level of subjective probability between two entities, a trustor and a trustee, which is formed through the direct observation nature and/or recommendation from trusted entities. Today, there is no special trust evaluation model for cloud computing environment. Hence, in this paper, we present a trust model based on fuzzy mathematics in cloud computing environment according to success and failure interaction between cloud entities.
