【Abstract】 A quantum key transmission model based on entanglement switch and teleportation was proposed. The model ensures the security and validity of the relay node in the quantum key relay transmission channel based on the network structure of the trusted control center.The method of quantum entanglement channel is used to ensure that the quantum key is not directly transmitted on the relay node and the quantum channel, so the security of the quantum key is guaranteed. Due to the quantum teleportation characteristics, the users which have quantum entanglement channel can directly access quantum key agreement, and jointly determine the final quantum secret key, while the quantum repeater node cannot obtain. This method effectively prevents the common attack patterns and ensures the security of the quantum shared secret key.Finally, the system performance and efficiency of the proposed model are analyzed. Research shows that, the quantum information transmission performance of the model increases along with the increase of the probability of success of the original quantum entanglement, and the original quantum key has high efficiency.更多还原
