一种云计算环境下的访问控制方法

onsidering the problem that the role of dynamic authorization and the behavior monitoring after authorization in access control model of cloud computing, a new access control model was proposed based on trust and behavior monitoring for cloud computing.This model can dynamic change of users' Behavior Trust by monitoring the behavior in resource access,protect the cloud computing environment; Realization the initial authorization and Reauthorization in access control by change of users' Comprehensive Trust.This model have the advantages of the traditional access control, At the same time it is more secure and efficient for user authorization. it is also can protect the cloud computing environment in process of resource access.
