【摘要】 本文描述基于微核心技术的国产操作系统ＣＯＳＩＸＶ２．０中文件系统服务器（ＦＳＳ）的安全性设计．通过对ＦＳＳ的结构和流程的研究，以及对安全属性表示方法这一基本问题的讨论，确立了一种在基于微核心的多服务器体系结构中ＦＳＳ安全性的设计方案．本文重点讨论了ＦＳＳ安全子系统的设计和实现，包括策略开关表和安全属性的不同表示法之间的转换等．更多还原

【Abstract】 This paper discusses the security design for the file system server(FSS) in micro-kernel based nationalized operating system (COSIX V2. 0). Based on the study of FSS and the discussion of security attribute representation methods, the security design scheme for micro-kernel based FSS is formed. The FSS security subsystem is discussed in depth, including security policy switch table, conversion between different security attribute representations, and so on.更多还原
