A quantum signaling tree transmission system of multi-user is presented, and the transmission process of signaling is described. The damage model of Trojan horse attack to signaling in the transmission process and the repair necessity are studied. The idea of quantum key distribution is introduced to the safety of quantum signaling in direct communication, and non-orthogonal quantum states are analyzed to overcome the problem of Trojan horse attack that will improve the safety of the signal transmission. Quantum signaling tree transmission system of multi-user is improved, and a new general transmission model of multi-user quantum signaling tree topology is presented.The result shows that repair strategy of multi-user quantum signaling transmission system being attacked can effective detect the Trojan horse attack, and increases distance of security transmission, to ensure the signaling transmission process safely and effectively.
