With the proliferation of cloud computing, the way of reasonable establishment of trust relationship among entities, as a vital part for forming security mechanism in cloud computing environments, is attracting increasing attention. This article introduces a trust management model based on fuzzy set theory and named TMFC including direct trust measurement and computing, connecting, and trust chain incorporating where the issue of recommended trust similarity has been addressed to prevent the behavior of associated cheat of middle nodes. And this model is geared toward the cloud users who are making their decision on whether to use services of some cloud computing providers by giving them trust evaluation sets about providers and then building reasonable trust relationship between them. Our motivation is trying to propose a new idea and method on trust management in cloud computing and further studies are still required to justify the rationality and practicability of this model.
