为将策略与机制分离的思想应用到访问控制模型，本文引入规则引擎技术，用规则来表示具体的访问控制策略，利用Java反射机制实现用户属性的实时加载和规则的动态执行，增强了规则引擎的灵活性，且通过对Rete算法的研究，提出基于多规则节点共享的规则匹配算法，提高规则匹配效率。
為將策略與機製分離的思想應用到訪問控製模型，本文引入規則引擎技術，用規則來錶示具體的訪問控製策略，利用Java反射機製實現用戶屬性的實時加載和規則的動態執行，增彊瞭規則引擎的靈活性，且通過對Rete算法的研究，提齣基于多規則節點共享的規則匹配算法，提高規則匹配效率。

In order to apply the ideal of separating strategies from mechanism to access control, we proposed a kind of rule engine technology in access control model.The access control strategies were represented by rules.In the engine, attributes were loaded on real-time and rules were executed dynamically by Java reflective technology, which gets better flexibility.Then this paper pro-posed a rule matching algorithm based on the sharing node in multi-rule by researching on the Rete algorithm, which can improve the matching efficiency.
