RETRACTED ARTICLE: A New Trust Evaluation Algorithm Between Cloud Entities Based on Fuzzy Mathematics

High security of cloud computing is one of the most challenges to be addressed before the novel pas-as-you-go business paradigm is widely applied over the internet. Trust brings a novel means to improve the security and enable interoperability of current heterogeneous independent cloud platforms. However, there is no special trust evaluation model for cloud computing environment. Hence, this paper presents a new trust model based on fuzzy mathematics in cloud computing environment according to success and failure interaction between cloud entities based on the properties and semantics of trust. To compute trust in cloud systems, an algorithm based on proposed model is given. Simulation results show that the proposed model has some identification and containment capability in synergies cheating, promotes interaction between entities, and improves the performance of the entire cloud environment.
