摘　　要：本文基于描述逻辑的本体技术在不同的系统中利用相同的分布式的词汇表来实现知识的共享,从而达到不同自治域的角色权限的统一。此外,由于角色互斥是角色访问控制中至关重要的限制之一,本文利用描述逻辑的语法完成了角色互斥的本体实现。In this paper,knowledge sharing is realized by the same distributed vocabulary, which is utilized by the ontology based on description logic in different systems. It leads to the unification of the roles and authorities in multi- autonomy domains. Besides, because the mutual exclusion of roles is one of systems, we achieve the ontological mutual exclusion of roles by the most important restrictions in role-based access control the grammar of description logic.

关 键 词：角色访问控制 本体 角色互斥 描述逻辑
