Abstract:

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 archi   tecture, especially at the hardware infrastructure, to search more essential solutions to security. This paper surveys and evaluates some typical hardwa descriptions and analysis, we propose a s  ecurity architecture that is supported by hardware, independent of the operating system, and determined by users.

Key words: security, architecture, hardware, operating system
