摘要
为了更好的保护节点关系所携带的信息以及XML的敏感信息,提出了利用"块"来组织的访问控制策略,并使用虚节点来指定与关系相关的机密限制。对具有块概念的XML-BB访问控制模型进行了研究,该模型能够隐藏不同块间节点的关系,以一种细粒度访问控制加强了XML敏感信息的保护。实验结果表明了该模型的可行性。
To protect information carried by relationships and sensitive XML information well, the access control policy using the new concept of block is suggested. Virtual nodes are provided to specify confidentiality restriction associated with some relationships. An access control model, called XML-BB （XML block based access control）, including this concept of block is presented. The model is used to hide relationships between nodes selected in different blocks and strengthens the protection of XML sensitive information by a fine-grained access control. The implementation of this model is demonstrated to be feasible.
