| 摘 要： | 提出的基于担保的Web服务访问控制模型采用形式化的方式描述，核心思想就是主体与对象之间通过担保人建立联系，担保人为主体颁发授权担保，多级担保形成一条担保链，通过担保链,主体可以得到对象一定信任度的授权；给出了基于担保的Web服务访问控制模型的授权决策算法，并通过实例说明了基于担保的授权决策过程。

| Abstract: | This article presented a new access control model for Web services that bases on guarantee(s). It was a formal model, and the key point of the model was that the subject and the provider of the Web services could contact with one another through a guarantor(s), which could made a guarantee for the subject. Multi guarantees made up a guarantee chain. By using the guarantee chain, the subject could get the authorization of the Web services to some degrees of trust. This article also described an access decision algorithm and an application example of this model. |
