摘　　要：文章借鉴可信计算思想,从可信支撑角度提出了一个基于通用计算平台的可信支撑框架(TSF)及原型的设计,并就该框架在通用计算平台上如何应用进行了研究,提出了一种实用的应用模式。该框架对TCG定义的TPM在概念和功能上进行了扩展,设计了独立于通用平台的可信支撑模块(TSM)。对比TPM,TSM更具实用性,且本质上并不降低其安全强度。文章提出的可信支撑的设计思想是从可信支撑角度对可信计算体系结构研究的一种尝试,具有一定的指导意义。Reference to the idea of trusted computing,this paper presents a trusted supporting framework and the design of its prototype from the point of view of the support of trust.Then the problem how to apply this framework on ordinary computing platform is researched and a practical application mode is proposed in this paper.The framework extends the conception and capability of the TPM defined by TCG,and designs the trusted supporting module,which has more practicability compare to the TPM and essentially doesn＇t degrade its security strength.The idea of supporting for trust presented in this paper has the guiding significance on the study of trusted computing architecture.It is an attempt from a standpoint of supporting of trust to establish the new architecture for trusted computing.
