| 摘 要： | 在BLP(Bell-La Padula)信息安全模型的基础上提出了DBLP(Dynamic Bell-La Padula)模型.DBLP模型考虑了客体安全级别的动态变化,并给出了支持该变化的算法描述.在将其应用到XML文档的访问控制中时,讨论了在这种模型下面向XML文档的典型操作,给出了一种可行的实现机制的体系结构,并指出了新模型可能带来的负面效应.

| Abstract: | DBLP(Dynamic Bell-La Padula) model is presented on the basis of BLP model.The dynamic change of secure grade of objects is considered,and the arithmetic for the change is described in DBLP model.The model is used for access control XML documents,and some typical operations for XML documents are discussed.The available system architecture for implementation is introduced,and some affects are pointed out. |
