摘　　要：计算平台作为信息基础设施的基本组成单元,一直是黑客攻击的重点。随着国产处理器性能的逐年提高,在中美贸易摩擦加剧的大背景下,我国关键信息基础设施将越来越多的选用国产处理器。使用国产处理器构建自主可控的计算平台将是一大趋势。通过分析采用国产处理器后可信边界的变化,提出了一种基于国产处理器的可信计算平台体系结构,分别给出了基于国产龙芯和飞腾CPU的典型软硬件参考设计,达到了不增加额外硬件成本,安全防护与计算并存的效果。As the basic component unit of information infrastructure,computing platform is always the focus of hacker attacks.With the improvement of the performance of domestic CPU year by year,under the background of intensified trade friction between China and the United States,more and more domestic processors would be used in China’s key information infrastructure.It will be a big trend to build an autonomous and controllable computing platform with domestic CPU.By analyzing the changes of trusted boundaries after using domestic CPU,a trusted computing platform architecture based on domestic CPU is proposed.The typical reference designs of hardware and software based on the domestic Loongson and Phytium CPU are given respectively;this achieves the effect of coexistence of security protection and calculation without additional hardware cost.
