In　order　to　realize　trusted　measurement　of　the　running　states　of　operating　system　and　application　programming,　considering　multi-hop　feature　of　wireless　Mesh　network,　two　steps　were　carried　out　to　evaluate　the　system＇s　trust:　starting　states　and　runtime　states.　The　values　stored　in　PCR　(platform　configuration　registers)　were　used　to　measure　and　evaluate　starting　states,　and　grey　relevance　analysis　method　to　evaluate　runtime　states.　And　then　the　proposed　trust　evaluation　mechanism　was　implemented　in　trusted　network　connections　of　wireless　Mesh　networks.　Moreover,　in　network　simulations,　untrusted　nodes　can　be　detected　effectively　and　false　detection　rate　is　less　than　10%,　which　shows　the　performance　is　good.
