ODP环境中全局安全系统的拓扑结构

ＯＤＰ环境中的全局安全系统是由各个安全域通过安全联接而成的，但是安全域之间的关系、全局安全系统的结构却是错综复杂的，组织和管理好全局安全系统是一个非常重要的问题。文中提出了全局安全系统的三种拓扑结构：网状拓扑、树状拓扑和综合拓扑，并根据安全政策和安全对象，讨论了各种拓扑的特点和构成条件。

Topology of the Global Security System for ODP Environment

The global security system for open distributed processing(ODP)environment consists ofsecurity domains associated with security association.Because of the complex of relationship betweensecurity domains and the complex of architecture of the global security system,both the organization and the management of the global security system are very important.This paper presents three types of topologicalarchitectures(net topological,tree topologleal and combination topologcal)of the global security system. Onthe basis of the sets of objects and the sets of security policies,the characters of every type topologcalarchitecture are diseussed,and the construction conditions of the topological architecttires are presented inthis paper.The topological architectures are helpful for organzing and managing the global security system.
