Embodiment Construction

[0029] The embodiments of the present invention are described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following implementation example.

[0030] like figure 1 As shown, this embodiment includes the following steps:

[0031] 1) All existing legitimate wireless mesh network nodes in the wireless mesh network, including multiple infinite mesh network nodes (MA) and mesh network key distribution nodes (MKD), share a current pre-shared key Encrypt all data transmitted over the wireless channel. At the same time, the wireless mesh network nodes in the network ensure the connection between all nodes and the Internet through self-organization.

[0032] 2) A candidate wireless mesh network node (Candidate MP) hopes to join the current wireless mesh network, ...

Abstract

The invention relates to a safety communication method of a wireless mesh network which belongs to the technical field of network. The method comprises the following steps: requesting initial authentication, starting an initial authentication protocol procedure by an authentication server and performing enciphered data communication by a pre-shared key and other legal wireless mesh network nodes in the wireless mesh network to realize functions of the wireless mesh network. The method meets new requirements of dynamic self-organization of the wireless mesh network, also provides safety performance approaching to 802.11 standard requirements for the network. The method is based on a wireless network communication standard of 802.11 protocol family, and is applicable to the wireless mesh network established based on 802.11 link. The method provides simple frame and structure, ensures compatibility and flexibility, and is easily realized.

Description

technical field [0001] The invention relates to a method in the field of network technology, in particular to a wireless mesh network security communication method. Background technique [0002] Wireless Mesh Network (Wireless Mesh Network) is a multi-hop self-organizing wireless network structure completely different from traditional wireless networks. In a traditional WLAN, each client accesses the network through a fixed wireless link connected to an access point, and each access point is connected to the Internet through a wired network. In a wireless mesh network, any wireless mesh network node exists as an AP and a transit router at the same time. Several nodes are connected to the Internet through a wired network, and other nodes communicate with each other through a multi-hop wireless link through a wireless mesh network routing algorithm. Internet connection. The user can move within the coverage area of ​​the wireless mesh network signal and access the Internet t...
