Software　Defined　Network　(SDN)　architecture　has　been　widely　used　in　various　application　domains.　Aiming　at　the　authentication　and　security　issues　of　SDN　architecture　in　autonomous　decentralized　system　(ADS)　applications,　securing　the　mutual　trust　among　the　autonomous　controllers,　we　combine　trusted　technology　and　SDN　architecture,　and　we　introduce　an　authentication　protocol　based　on　SDN　architecture　without　any　trusted　third　party　between　trusted　domains　in　autonomous　systems.　By　applying　BAN　predicate　logic　and　AVISPA　security　analysis　tool　of　network　interaction　protocol,　we　can　guarantee　protocol　security　and　provide　complete　safety　tests.　Our　work　fills　the　gap　of　mutual　trust　between　different　trusted　domains　and　provides　security　foundation　for　interaction　between　different　trusted　domains.
