For　the　identification　of　client　identity　issue　in　trusted　network,　in　this　paper　a　trusted　network　identity　identification　scheme　based　on　the　ID　is　presented.　It　adopts　public-key　cryptography　with　no　certificate　to　generate　the　private　key.　This　scheme　avoids　the　revocation　of　public-key　certificate　and　the　key　escrow　problems.　Meanwhile　in　this　paper　we　use　the　random　oracle　model　to　prove　the　security　of　the　scheme.　The　results　show　the　scheme　is　efficient　and　easy　to　implement.
