Background: Credibility problems in the cloud service are very important issues in cloud
Methods: By using the small world model in complex networks, a relationship model of cloud computing
alliance can be established; defense game model is established under the cloud alliance by game theory; by
combining the self-organization of small world model with self-constraint binding of game model, offensive
and defensive game model of incomplete information is realized. Through the simulation experiments, they
verify trusted resource management functions in the cloud computing alliance.
Results: Moreover, by using unsupervised and supervised management conditions, access requesting
nodes for cloud service and comparative analysis of respondents in the cloud service get a better
resource management effect.
