在云计算中，对大规模的资源提供一种安全有效的访问是其一个很重要的组成部分。在传统的分布式访问控制模型中．服务请求者将主体属性或能力等披露给提供资源者．访问控制决策完全取决于以资源请求者能力和安全策略为输入的一致性证明。但是。这些主体属性与能力等通常携带了大量信息。势必给云环境中的互操作带来许多安全隐患和风险。针对云环境的特点，提出一种针对云环境资源的安全模型，采用一种基于属性的访问控制技术来解决云计算环境下复杂和困难的安全问题，并且提出了一个安全管理模型来动态的决定对资源的访问控制．通过对资源属性的动态改变来达到对资源的安全访问的目的。

In large-scale cloud computing resources to provide a safe and effective access to it is a very important part. In traditional distributed access control model, the service requester to the ability （Ability） or the main attribute （Attribute） disclosed to other resource providers, access control decision depends entirely on the request, the requester security policy and resource capacity of the input consistency proo~ However, the main attributes of these abilities and usually carry a lot of information is bound to cloud interoperability brings a number of safety hazards and risks. For the characteristics of the cloud environment presents a security for the cloud model of environmental resources, using a property-based access control cloud computing technology to solve complex and difficult environment, safety, safety management and proposed a decision model to dynamically control access to resources through the dynamic changes in the resource properties to secure access to resources to achieve the purpose.
