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.

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。
