云计算作为一种新的计算模式，可以为用户提供虚拟化、可扩展的Web服务，但同时也面临着严峻的安全挑战。访问控制是保证云计算安全的重要措施之一。但是将传统的访问控制模型直接应用到云计算中并不能解决云计算开放条件带来的不确定性和脆弱性。在云计算环境下，只有保证交互双方的安全可靠，才能有效保障用户与云交互过程中的数据安全。因此，建立用户与云平台之间的互信关系是云计算环境下实现新型访问控制方法的关键。结合信任管理，提出了一种基于互信任的访问控制模型。MTBAC模型综合考虑了用户的行为信任和云服务节点的可信度。通过互信机制建立用户与云服务节点之间的信任关系。将MTBAC模型应用到云计算环境中，解决了访问控制的安全问题。仿真实验表明，MTBAC模型能够保证用户与云服务节点的交互。
As a new computing mode, cloud computing can provide users with virtualized and scalable web services, which faced with serious security challenges, however. Access control is one of the most important measures to ensure the security of cloud computing. But applying traditional access control model into the Cloud directly could not solve the uncertainty and vulnerability caused by the open conditions of cloud computing. In cloud computing environment, only when the security and reliability of both interaction parties are ensured, data security can be effectively guaranteed during interactions between users and the Cloud. Therefore, building a mutual trust relationship between users and cloud platform is the key to implement new kinds of access control method in cloud computing environment. Combining with Trust Management(TM), a mutual trust based access control (MTBAC) model is proposed in this paper. MTBAC model take both user's behavior trust and cloud services node's credibility into consideration. Trust relationships between users and cloud service nodes are established by mutual trust mechanism. Security problems of access control are solved by implementing MTBAC model into cloud computing environment. Simulation experiments show that MTBAC model can guarantee the interaction between users and cloud service nodes.
