摘　　要：为增强安全关键系统的高可信能力,在分析高可信保障机制现状的基础上,提出了一种多层次的高可信软件架构。该架构采用"时空分离"思想、虚拟机技术,为基于MLS的嵌入式安全关键系统提供了一种整体解决方案。基于该架构,研究了多层次的安全和防危策略管理方法、信息流控制机制、可信软件的评估和认证方法,为安全关键嵌入式系统提供可认证的安全服务。To improve the dependability of security/safety-critical systems, after analyzing status quo of high dependable safeguard mechanism, a multi-layered architecture based on the concept of separation and the VM is proposed, which supports applications with multi-level security. This paper researches multi-layered security/safety policy, the information flow control mechanism and the evaluation and certification for trusted software. This architecture can provide trustworthy services for the embedded security/safety-critical systems.
