To solve the problem of access control among different security domains in networks, an access control model is presented based on role and trust degree. Each role associates with a trust value, the role evaluation weights are defined in terms of user's role rank and the trust degree is calculated according to the role evaluation weights and role behavior. Direct trust degree, recommendation trust degree and feedback trust degree are introduced in this model to achieve fine-grained access control. The three trust degrees mentioned above participate in the comprehensive trust degree evaluation by adjusting their weights. Simulation is conducted in local area network environment in which a web system is used to construct an access control model with multi-domain. Experiment demonstrates that the model is of higher security, expansibility and flexibility.
