The　trusted　boot　is　a　hot　spot　in　trusted　computing　field.　User’s　identity　authentication　and　trusted　measurement　are　used　to　deal　with　security　threats.　But　it　is　difficult　to　implement　the　general　trusted　boot　based　on　hardware,　which　can　be　bypassed　easily　by　software.　In　order　to　solve　the　above　problem,　a　scheme　of　trusted　boot　is　presented　based　on　the　universal　smart　card.　It　does　not　change　the　hardware　and　the　firmware　of　the　smart　card　and　the　terminal　device.　The　core　method　combines　user’s　identity　authentication　with　trusted　measurement.　It　binds　user’s　identity,　smart　card　and　terminal　device　to　ensure　the　trusted　boot　of　terminal　device.　The　trusted　computing　mechanism　can　be　extended　from　power　on　to　the　application　layer.　Ultimately,　experiments　prove　the　security　of　boot　and　simplification　of　the　implementation.　©　Springer　International　Publishing　Switzerland　2016.
