Wireless　mesh　networks　(WMNs),　with　the　characteristics　of　rapid　deployment,　flexible　networking,　decentralized　planning,　etc.,　are　widely　used　for　emergency　services　such　as　police,　fire　and　emergency　medical　services　to　improve　the　efficiency　of　emergency　communication.　For　rapid　response　to　civil　aviation　emergency　incidents,　secure　and　effective　emergency　communication　becomes　particularly　important　for　better　decision　making　whether　to　save　lives　or　to　preserve　properties.　In　this　paper,　we　propose　a　mesh　network　architecture　adapted　to　civil　aviation　emergency　communication　and　a　user　admission　scheme　for　civil　aviation　emergency　mesh　networks　based　on　an　enhanced　elliptic　curve　signcryption.　The　results　of　security　and　efficiency　analysis　show　that　the　proposed　scheme　can　effectively　preserve　the　properties　of　confidentiality,　authenticity,　privacy　and　behavior　tracing　between　the　emergency　responding　personnel　and　the　emergency　command　center　and　lower　the　cost　of　computation　and　communication　by　20%　and　25%　respectively　in　comparison　to　user　admission　schemes　based　on　traditional　elliptic　curve　cryptography.
