The　Trusted　Platform　Module　(TPM)　is　an　embedded　cryptographic　processor　and　non-volatile　storage　device　which　designed　to　be　tamper-proof.　There　are　many　sensitive　data　in　the　TPM.　We　present　a　sensitive　data　backup　and　recovery　mechanism　in　the　TPM　used　in　some　abnormal　situations　such　as　power　outage　to　ensure　the　data　consistency　and　analyze　the　feasibility　of　this　mechanism　in　detail.　Besides,　we　use　the　backup　stack　and　mark　zone　cyclically　to　avoid　hardware　malfunction　in　this　mechanism.　©　2011　IEEE.
