摘要：Cloud computing is a new paradigm which enables users to reduce their costs and is advantageous to both the serving and served organizations. However, security issue is a major concern in the adoption of cloud computing. The most effective way of protecting cloud computing services, resources and users is access control. This paper intends to provide a trust-based access control mechanism for cloud computing considering its multi-domain aspects. Firstly, trust is introduced into cloud computing environment and trust relationships between users and cloud platform are built. It also analyzes the difference between intra-domain trust and inter-domain trust. Furthermore, a role-based access control framework combined with trust degree in multi-domain is given from this paper. Access control in local domain directly applies RBAC model combined with trust degree, whereas in multi-domain it contains the conception of role translation. The simulation results show that the proposed method is more suitable to cloud environment and definitely can improve the reliability and validity of the system.
