摘　　要：可信计算芯片是可信计算的核心部件,承担着对可信计算平台软硬件系统的完整性度量、完整性报告和可信存储等任务。目前,国外可信计算芯片大多采用国际可信计算组织的可信平台模块TPM规范,而国内可信计算芯片依据的是可信平台控制模块规范。文中从芯片的主要功能、组成结构、接入方式和工作模式等方面,研究和分析了两类常见可信计算芯片,最后讨论了可信计算芯片面临的各种挑战。Trusted computing chip, as the core component of trusted computer, bears the responsibilities of completeness measurement, completeness reporting, and trusted memory. Nowadays, most of the trusted computing chips abroad adopt trusted platform module TPM from international trusted computing organization, while the trusted computing chips at home are based on TPCM. From main functions, constitutions, access mode and working mode, this paper treats of and analyzes similarities and dissimilarities of these two kinds of trusted computing chips. Finally, various challenges confronted with by trusted computing chips are also discussed in this pape r
