摘要： 为提高XML文档资源访问控制的安全性，依据RBAC对XML组件具有复杂约束以及模式与元素之间关系的良好重用机制的特性，构建了一种新的访问控制模型—SRBAC。在此基础上，提出了相应目标访问控制算法TDACA，创建了相应策略，验证了SRBAC的有效性，从而实现了有效的访问控制和实例级的认证，保证了XML文件的安全使用。

Abstract: In this paper，a Role-Based Access Control（RBAC） model based on XML schema is proposed for solving security problems of accessing XML documents.XML schema supports complex constraints for XML components and provides a mechanism to build rich reuse relationships between schemas and elements.Based on these features our model extends the RBAC96，corresponding algorithm-TDACA（Target Document Access Control Algorithm） is also presented，which provides a fine-grained access control and also supports instances-level authorization methods.
