摘要： 操作系统结构化是目前安全领域的一大难题。以无干扰模型为基础，提出了一种基于分层隔离的进程环境安全模型，给出了进程环境安全的定义和条件。然后对系统结构化要求进行了形式化的描述，并证明通过提出的结构化方法可以获得安全的进程环境。最后结合经典无干扰理论，将本模型由进程环境扩展为适用于整个系统安全的模型。
关键词: 操作系统，结构化，无干扰，进程环境
Abstract: Structural protection of operating system is currently a difficult problem in security field. This paper studied a process execution environment model based on hierarchy isolation, and gave definition and conditions of process environment security. Then we formalized structural requirements of process environment, and proved that a secure process environment can be available by structured method proposed. Finally combined with classic non-interference theory, the security model was extended from process environment to the whole system.
Key words: Operating system, Structural protection, Non-interference, Process environment
