The user and services provided by resources in Grid environments are dynamic. Therefore, the malicious nodes may exist in Grid system. It will significantly affect the Quality of Service (QOS) requirements of users, even lead to the economic loss of user in the Grid economic environment. So a certain resource management scheme has to be implemented in Grid economy environments to ensure the environments working properly and achieve better scalability. It is recognized an effective measure which uses Reputation to control the access of malicious nodes. In this paper, we design a distributed reputation control architecture which is based on Virtual Organizational Domains (VOD) and propose a reputation calculation algorithm which spans these domains. The inner structure and this framework are also detailed discussed here. At last, through the simulating experiments, it can be proved that this architecture could block the assessment of malicious nodes effectively and improve the efficient and stability of nodes in Grid economy environments.
