Trust　platform　is　key　technology　of　trusted　computing.　How　to　verify　if　a　model　is　trusted　in　theory　is　a　signification　research　work.　In　this　paper,　a　trust　level　evaluation　method　of　trusted　computing　model　based　on　fuzzy　logic　is　presented.　By　the　similarity-based　weighted　fuzzy　reasoning　method,　the　fuzzy　trust　value　between　entities　which　have　no　direct　recommendation　in　trust　chain　can　be　gained　and　the　trust　level　of　trusted　models　were　evaluated　based　on　the　trust　value　calculated.　This　paper　provides　a　new　valuable　way　for　studying　trust　evaluation　of　trusted　computing　models.　©　2010　IEEE.
