As Wireless Local Area Network (WLAN) become more widely deployed, WLAN security has become a serious concern for government, enterprises, national defense, military and other places. Generally, the security requirements for a WLAN include data confidentiality, integrity, mutual authentication, and availability.As we all know, WLAN apply the electromagnetic technology to replace the old twisted-pair copper wires, which constructed quickly transmission system and led to the ideal boundary "carry the information technology to facilitate the world". WLAN information is spread in the air.It is easy to cause illegal malicious attacks. The 802.11i specification defines two classes of security algorithms:Robust Security Network Association (RSNA), and Pre-RSNA. Pre-RSNA security consists of Wired Equivalent Privacy (WEP) and 802.11 entity authentication. RSNA provides two data confidentiality protocols, called the Temporal Key Integrity Protocol (TKIP) and the Counter-mode/CBC-MAC Protocol (CCMP), and the RSNA establishment procedure, including 802.1X authentication and key management protocols.The study fields are WLAN and its extension for quantum network.It includes six branches. In section 1, to compensate for WLAN security flaws, the quantum cryptography is introduced. Quantum technology on GHZ improved WLAN data security. This protocol required to use the classical and quantum key co-management model. In the four-way process on GHZ stats, the original key hieratchy was replaced by quantum Pairwise key, which solved TKIP, CCMP protocol shortcomings. This change adapted to existing network protocols and also provided a higher level of security.In section 2, this article uses the cluster concept in the Bluetooth network, and expands the network complexity. Suppose quantum channels without noise, we design a mutual quantum secure direct communication protocol, which shared a sequence of single photons and Greenberger-Horne-Zeilinger (GHZ states) in the quantum networks (cluster S, cluster M, cluster D). In this scheme,S1,S2,,...,Sn-1 members in cluster S directly encode their respective keys on the states of single photons, then generalize this situation transmit to the last one of the cluster. The Sn encodes the secret message directly on a sequence of particle states and transmits them to D1,D2...,Dm supervised via one of the cluster M by GHZ states, where it is a set of ordered maximally entangled three-particle states, initially established sharing by three separated parties with Sn, Mj and each of the cluster D. We also prove that it is unconditionally secure. This scheme is feasible with present-day techniques. The feature of this protocol is that the communication between two clusters depends on the agreement of the third cluster.In section 3, it continues to study the development context of next-generation network and practical application of quantum cryptography. Suppose quantum channel without noise, it proposed a star quantum network framework composed by N+1 quantum nodes and designed two types of security protocols. The first protocol is applied in simple star network framework with compose of 2+1 nodes. M is the master node and trusted node. S1 sends signature string to S2. M,S1,S2 are Sharing 2N GHZ-like states, ensure the legitimacy and security keys. The second protocol is applied in a star quantum network that 3+1 nodes share Smolin states.The four nodes respectively send code sequence to ensure network security. The protocol is proved that it is secure against three eavesdropper two eavesdroppers,one eavesdropper. Theoretical analysis shows that the two protocols for the eavesdropper have a very high security.Four, from the classical network to the quantum network across the network, the quantum mechanics will be more deeply applied to WLAN secure communication system. In the case of quantum channel without noise, a mutual quantum secure direct communication protocol which shared the EPR state in the multihop ring quantum networks is presented. The communication is based on Einstein-Podolsky-Rosen pairs (EPR pairs) and teleportation between the quantum nodes. After insuring the security of the quantum channel through Controlled-NOT (CONT) gate operations and Hadamard (H) gate operations on them., the sequence sent to t2 from t0 through t1, then multihop transmits them to t4,...,t2N supervised via t3,...,t2N-1.The protocol depends on EPR to guarantee the security.Five, the actual situation in the quantum channel can not be possible without noise. In this paper, a quantum information correction protocol using quantum CSS (Calderbank-Shor-Steane) codes is proposed. In the single cluster quantum network, the protocol aim to correct the three errors:bit reversal error, bit phase error, bit reversal and phase error. Master node and slave nodes verify and compare by CSS codes, obtain the correct date. Security of this protocol is based on the assumption that decoding general linear codes.Six, though contrast of classic network, this article proposed next generation wireless networks with quantum technology. First, analysis of the problems facing the next generation of wireless networks and the current research, followed by proposing the wireless network concept for next generation which is inclusive of quantum networks and also proposed cross-layer five quantum network protocols: heterogeneous physical layer, data on quantum information link layer, network layer of quantum information, quantum information and classical information transmission layer, the quantum software application layer. The purposes adjust the layers, adapt the development of next generation network needs and improve their overall performance.
