This paper addresses the security WLAN protocol based on Quantum Greenberger–Horne–Zeilinger stats to overcome the flaws of wired equivalent privacy, temporal key integrity protocol, counter mode with CBC-MAC protocol, IEEE802.11i protocol, and ensure wireless communication information security. Our main theorem have two important corollaries. The first is an ingenious application of quantum mechanics to apply in wireless communication theorem. The second is the proof of the protocol that Eve invariably introduces errors within communication network if it wants to gain useful information. Here the novel idea is that quantum cryptography guarantees the security of wireless communication information.
