Trusted　computing　provides　an　efficient　and　practical　way　out　for　system　security　problems　based　on　a　trusted　hardware,　namely　the　root　of　trust,　e.g.,　Trusted　Platform　Module　(TPM),　Trusted　Cryptographic　Module　(TCM),　Trusted　Platform　Control　Module　(TPCM),　so　on　and　so　forth.　However,　current　applications　calling　for　trusted　functions　have　to　use　either　the　user-space　trusted　interfaces　(e.g.,　Trusted　Software　Stack　(TSS)　API)　or　to　implement　customized　APIs　on　top　of　the　trusted　hardware　driver;　both　of　them　are　well　known　of　steep　learning　curve,　which　indicates　error　prone　and　low-efficient　development　and　complex　maintenance　for　the　application　of　trusted　software.　This　paper　presents　a　new　trusted　encapsulation　architecture　and　the　proof　of-concept　system　with　the　aim　to　mitigate　the　gap　between　the　current　obscure　trusted　APIs　and　the　actual　trusted　applications　for　trusted　software　development.　Our　system　can　provide　high-level　and　much　simplified　trusted　transaction　interfaces　for　user　applications,　which　can　rapidly　reduce　the　development　and　maintenance　work　for　the　developers　and　users　without　too　much　performance　costs.　We　also　present　a　secure　remote　login　use-case　using　mainly　the　binding　and　unbinding　trusted　functions　of　our　trusted　encapsulation　architecture.　©　Springer　International　Publishing　Switzerland　2016.
