Trustworthiness of resources is the foundation of virtual computing environments (VCE). Using identical information of resource is an ordinate method to achieve trustworthiness. However, it may conflict with identity privacy problem, an important security issue in VCE, that tries to make resource anonymous. A trust model is proposed to enhance resourcespsila identity privacy by changing pseudonym in fully distributed VCE, while each resourcepsilas trustworthiness can be evaluated by upper applications. Simulation results show that the model achieves considerably fine performance with measurements of resource trustworthiness evaluation error, resource selection success rate, and message overhead.
