摘　　要：当前,计算的安全性变得日益重要,而安全现状却变得越来越严重。为此,我们需要从计算机体系结构的层次尤其是在底层硬件基础上寻求更根本的安全解决方法。本文综合评价了若干有代表性的硬件支撑的安全体系结构,分析了其积极的效果和存在的问题。基于上述分析,提出了一种硬件支持的、独立于操作系统且由用户自我决断的安全体系结构。Currently, computing security becomes more and more important, but its status seems worse than ever. So we need to work at the level of computer architecture, especially at the hardware infrastructure, to search more essential solutions to security. This paper surveys and evaluates some typical hardware supported security architectures, and analyzes their positive effects and existing problems. Based on these descriptions and analysis, we propose a security architecture that is supported by hardware, independent of the operating system, and determined by users.
