针对嵌入式计算机应用领域中越来越突出的信息安全问题。本文以uCOSII操作系统为基础,在其上增加了强制访问控制MAC模块。模块参照BLP安全模型,根据uCOSII特性设计出BLP修正模型,实现了对系统的强制存取控制。
Aiming at the increasingly prominent information security problems in the field of embedded computer applications. This article is based on the uCOSII operating system, which adds mandatory access control MAC module. BLP model is referenced to BLP model and the BLP correction model is designed according to uCOSII characteristics to achieve the mandatory access control to the system.
