【摘要】 系统保安是计算机科学研究中重要的领域，监控参照模式被公认为是一良好的系统保安结构模式，并被广泛应用于很多著名的操作系统中，如ＶＭＳ和ＵＮＩＸ均采用这一模式￣［１］。但是，这一模式在各系统中的实现却不尽相同。本文剖析了其在ＶＭＳ操作系统中的实现，从结构上对ＶＡＸ／ＶＭＳ系统保安进行了分析。更多还原

【Abstract】 System security is one of the important fields in computer science research.The reference monitor model is knows as an excellent one for system security structure and widely used in many well-known operating systems, such as VMS and UNXI. But its implementation is not all the same in different systems. The analyses on its implementation in VMS and VMS secuvity structure are presented in this paper.更多还原
