摘　　要：已有模型对WebServices的访问控制多数是静态的、粗粒度的,不能满足动态的面向服务的WebServices环境。为此提出了一个基于角色的WebServices动态访问控制模型(RBDAC),此模型可以根据用户访问时的上下文信息来激活角色分配和权限分配,并动态地做出访问控制决定。The current access control models are mostly static and coarsely grained; they are not well-suited for the service-oriented Web Services environments where information access is dynamic. In order to solve this problem, a role-based dynamic access control （RBDAC） model for Web Services was proposed. The RBDAC model can activate role assignments and permission assignments based on context information, and make access control decision dynamically.
