Access　control　is　the　basic　of　information　security.　It　is　always　used　to　protect　sensitive　information　and　critical　resources　from　malicious　attacks.　But　the　traditional　access　control　models　are　more　adapt　to　closed　network　environment.　And　there　are　more　and　more　unknown　threats　and　attacks　in　the　open　networks,　especially　the　mobile　networks.　To　solve　this　problem,　we　propose　a　new　access　control　model　which　is　applicable　to　the　open　mobile　networks　by　using　non-zero-sum　game　theory　in　this　paper.　The　model　is　composed　by　six　modules:　access　evaluation　module,　access　permission　determination　module,　non-zero-sum　game　theory　analysis　module,　decision-making　module,　result　evaluation　module,　access　feedback　module　and　a　prior　information　database.　And　in　this　model,　the　subjects　will　choose　to　be　more　honest　when　they　make　access　requests　because　they　all　want　to　get　more　permission　next　time.　Then　we　do　some　experiments　to　prove　this　fact.　©　2015　SERSC.
