摘要
提出了一种细粒度的XML推理控制模型及实现机制,解决了强制访问控制所不能解决的敏感信息推理问题;改进了算法,可快速获得解决敏感信息泄露的最佳方案;引入剪枝策略,实现了安全信息最大化发布。
A fine-grained inference control model was proposed and its implementation mechanism of XML document was given. It could solve the problem of sensitive information inference that couldn＇t be solved by MAC （Mandatory Access Control）. The algorithm was improved to obtain the best solution to sensitive information leakage quickly. The pruning methods were adopted to publish the secure information as much as possible.
