For　lacking　detailed　behavior　measurement　in　Trusted　Network,　current　measurements　are　mainly　based　on　identity　and　state　measurement,　in　this　paper　the　definition　of　network　behavior　and　description　of　behavior　adaptive　to　Trusted　Network　environment,　and　a　new　multi-dimensional　behavior　measurement　model　is　presented.　This　model　is　based　on　several　behavior　prosperities　such　as　individual　similarity　function,　group　similarity　function,　direct　trust　evaluation　function,　risk　assessment　function　finishes　trust　measurement　in　many　aspects,　and　is　dynamic,　fine-grained　and　adaptive　to　environment.　It　reduces　the　subjective　factors　of　behavior　measurement　through　the　establishing　of　categorization　weight　of　the　behavioral　prosperities　by　information　entropy.　The　experimental　results　indicated　that　the　model　presented　in　this　paper　is　more　effective　and　environmental　adaptable.
