With the development of cloud computing, the problem of identity management has aroused great concern in the industry. The identity authentication mechanism based on group signature ensures that the cloud service provider cannot backtrack the user's identity information through the outsourced data and is widely used in the identity management of cloud computing environment, but it cannot prevent the malicious user from illegally accessing the cloud service. In view of this shortcoming, the existing identity management model is improved, and the Trust Management and group signature mechanism are combined to design a trust based identity management model. This model first calculates the user trust degree and uses it as the basis of group signature grouping, then realizes the user authentication by using the group signature mechanism, which can not only guarantee the user's privacy, but also help the cloud provider to protect the resources. Experimental results show that this model can effectively identify malicious users and help cloud service providers to prevent malicious users from accessing resources.
