Security and interoperability is the biggest challenge to promote cloud computing currently. Trust has proved to be one of the most important and effective alternative means to construct security in distributed systems. In order to efficiently and safely construct entities' trust relationship in cloud and cross-clouds environment, this paper proposed a novel cloud trust model and a new cloud security framework. The propose trust model is domain-based. It divides one cloud provider's resource nodes into the same trust domain. It designs different trust strategies for different roles. Trust recommendation is treated as one type of cloud services just like computation or storage. Based on the proposed trust model, it introduced a novel cloud security framework with an independent trust management module. Using the proposed security model, it introduced some trust-based security mechanisms. Results of simulation experiments show that the proposed security model can achieve high transaction success rate with high trust accuracy.
