Abstract


Wireless LAN WLAN (wireless LAN) is the use of electromagnetic technology to replace the old underfoot composed of twisted-pair copper convenient data transmission system, to \Compared with the cellular network, WLAN has a higher data transfer rate, more suitable for government agencies, enterprises, national defense and other places. WLAN Because the data link layer of the media in the use of open, the message \Currently, WLAN security encryption protocol: Wired Equivalent Privacy (WEP), Temporal Key Integrity Protocol (TKIP), and Counter Mode Cipher Block Chaining Message Authentication Protocol (CCMP). This field of study and its extension for wireless LANs quantum network, a total of six branches. The first branch, in order to compensate for WLAN security flaws, including the introduction of quantum cryptography was proposed based on quantum technologies-GHZ state security key wireless LAN solutions. In the 802.1x authentication based on the use of classical and quantum key co-management model. In the four-step handshake process, the original key structural improvements for the quantization of the pairwise key hierarchy, so as to solve TKIP, CCMP protocol security shortcomings of poor, both compatible with the existing network protocols, but also for the network to provide higher security. The second branch of research, drawing on the concept of clusters in the Bluetooth network, expansion of network complexity. In the case of a quantum channel without noise, raised a number of key clusters multi-quantum network sharing agreement. Quantum build all nodes in the network cluster S, M, D, three nodes in the cluster of S1, S2, ..., Sn, M1, M2, ..., Mw, D1, D2 ..., Dm. S1, S2, ..., Sn-1 the key information is encoded and transmitted to the Sn. Sn optionally by a node in the cluster M M1, using GHZ state, then the key information to each node in the cluster D D1, D2 ..., Dm. Features: S, M, D, one or several nodes can not know the key, and only S, D in the agreement of all the nodes can share the key. The third branch of research, in-depth study of the development of the next generation network context and the practical application of quantum cryptography. In the case of a quantum channel without noise is proposed consisting of nodes N 1 star quantum network model, and the network is designed in two security protocols. The first protocol used by two 1 nodes. A master node, two from the node, respectively, with M, S1, S2 represents. Where M is the trusted node master node. S1 to S2 send quantum signature keys, three nodes share the 2N GHZ-like states, the use of GHZ-like states feature ensures the security of quantum signature key. A second protocol used consisting of 31 nodes quantum star network model, a master node, three from the node, respectively, with M, S1, S2, S3 that. Four-node shared by respectively Smolin states state, to ensure the security of the star network. Theoretical analysis shows that two protocols for eavesdroppers have a high security. The fourth branch, in the case of a quantum channel without noise is proposed 2N 1 nodes consisting of circular quantum network model and the network design key transport protocol. Quantum node t0 use CONT doors, H gate operation, the key to pass through t1 to t2, more jump sequentially through t3, ..., t2N-1 pass to quantum node t4, ..., t2N, the key passed to the final node. The protocol relies on EPR entangled pairs key security to protect. . The fifth branch of the actual situation in the quantum channel can not be without noise, quantum noise for a broadcast network, the reliability of the key issues, the design of a single cluster of multi-error correcting quantum key sharing protocol. Agreement from the primary node to any node in bulk and set the upper limit value data error, if it exceeds the upper limit value, the key data will be discarded. If, in the upper range of values, the node using quantum error correction code CSS reversed its position appears wrong, phase error, bit reversal and phase error correcting wrong three kinds of errors, to obtain the correct key data transmitted. The agreement resolves a key process in the mass errors generated due to noise, to achieve key data transmission reliability. The sixth branch, compared to classical networks, including quantum network proposed next-generation wireless networking concepts and associated elements. First, the analysis of next-generation wireless network research status, then propose including quantum networks in which the concept of next-generation wireless networks, and proposes a five-story quantum network protocols: heterogeneous physical layer, data link layer of quantum information, quantum information the network layer, the quantum and classical information message transport layer, application layer quantum software. Objective To construct the appropriate quantum network model to adapt to the development needs of the next generation network, to improve their network security.
