From the point of the safety in Cloud Computing and the virtual resource under the Cloud, here proposed a cognitive trust model of Cloud virtual resource, based on Bayesian, and the model supports the effective resource selection as a basis. Furthermore, on the basis of the description of process and question in virtual resource selection, here comes a Trust and Resource Scheduling oriented Cloud resource selection model which takes QoS, trust, resource scheduling and other indexes into account. After applying the improved CHC-TSSM Genetic Algorithm in the model, the simulation experiment confirms the feasibility and efficiency of the algorithm, which can resolve the trust and scheduling problem in resource selection effectively.
