Currently　Software　Define　Network　(SDN)　architecture　has　become　a　hot　topic.　Aiming　at　the　authentication　security　issues　of　SDN　network　architecture,　we　introduce　an　authentication　protocol　based　on　SDN　network　architecture　without　any　trusted　third　party　between　trusted　domains.　By　applying　AVISPA　security　analysis　system　of　network　interaction　protocol,　we　can　guarantee　protocol　security　and　provide　complete　safety　tests.　Our　work　fill　the　gap　of　mutual　trust　between　different　trusted　domains　and　provide　security　foundation　for　interaction　between　different　trusted　domains.
