Abstract

Due to highly distributed, non-transparency and dynamic natures of cloud computing, cloud users often confused whether cloud service providers could be trusted. Therefore, a certain trust mechanism or approach should be established to secure a cloud user in selecting a reliable cloud service provider while transactions are taking place. A new dynamic trust approach for cloud computing is proposed in this paper, and multi-level Dirichlet distribution is introduced to compute the value of trust degree. At the same time, confidence factor and time decay factor are taken into account in trust evolution. Simulations are to be set up to observe the performance of the approach, and the results show that the Dirichlet distribution approach for cloud computing is an effective and an efficiency solution in computing the value of trust degree.
