To　correct　the　problem　that　traditional　secret　sharing　scheme　can　not　take　precautions　against　cheat,　in　this　paper,　we　propose　a　rational　secret　sharing　scheme.　The　proposed　scheme　based　on　bilinear　pairing　is　verifiable　and　the　participants＇　cheat　can　not　work.　The　dealer　doesn＇t　need　a　secret　share　distribution.　Therefore,　the　scheme　greatly　improves　the　efficiency　of　secret　distribution.　In　addition,　the　trusted　party　is　eliminated　in　the　secret　reconstruction　phase.　The　gain　of　following　the　protocol　is　more　than　the　gain　of　deviating,　so　rational　player　has　an　incentive　to　abide　by　the　protocol.　Finally,　every　player　can　obtain　the　secret　fairly.　Moreover,　the　scheme　can　withstand　the　conspiracy　attack　with　at　most　m-1　players.　By　analysis,　we　find　the　scheme　is　secure　and　effective.
