📝 Abstract

In this paper, the implementation of an operating system oriented RBAC model is discussed. Firstly, on the basis of RBAC96 model, a new RBAC model named OSR is presented. Secondly, the OSR model is enforced in RFSOS kernel by the way of integrating GFAC method and Capability mechanism together. All parts of the OSR implementation are described in detail.

和数据库。对于在操作系统中的实现研究比较少而且不完善 [2] [3] 。 本文在实施 RBAC 之前，针对操作系统的特点对 RBAC96 模型进行细化和扩展。然后， 采用 GFAC 和 Capability 机制相结合的办法在红旗安全操作系统内核中实现 OSR 模型。 2 扩展 RBAC96 模型 RBAC96 是一个模型族 [2] ， 包括 RBAC0、 RBAC1、 RBAC2 和 RBAC3 等模型， 其中 RBAC3 是前三者的综合(见图 1) 。RBAC3 包括以下内容：
