Research and Analysis on Trusted Computing Chips

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 paper.
