Quantum communication has an irreplaceable role in the confidentiality of information compared with classical communication. The entangled state was used in the quantum communication networks to transmit information, and quantum wireless multi-hop networks communication can be realized by using the quantum entanglement swapping, thereby ensuring that information can be transmitted over long distances. Based on the security problems caused by the direct use of entangled states in quantum communication, this paper verifies the GHZ state in the quantum wireless network communication, so as to ensure the GHZ state is the perfect entangled state originally prepared, thus ensuring the safety of quantum communication.
