摘要： 提出了ODP环境的全局安全系统的格模型,给出了其中安全域的表示和构造;在这一格模型的基础上,导出了多安全级的全局安全系统的模型,该模型将安全系统中的安全域划分成了不同的安全级,并结合层次结构对安全系统进行组织和管理.

Abstract: A lattice model of the global security system is presented, and its expression and construction are discussed in this paper. Based on the lattice model, a global security system model with multiple security classes for ODP environment is derived, in which security domains are labeled as different security class, and the whole system are organized with multiple security classes and hierarchy.

Key words: open distributed processing (ODP), global security system, security object, security domain, security association, security classes, lattice, security policy
