Embodiment approach

[0031] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS, the second mesh network node detects the reception of the surrounding mesh network nodes by receiving beacon frames of the surrounding mesh network nodes, or the second mesh network node sends detection request frames. Signal Strength (Received Signal Strength, RSS) to discover the first mesh network node that has passed authentication, and use the first mesh network node as the authenticator to send a first access authentication request message to it.

[0032] S12: After receiving the first access authentication request message, the first mesh network node uses a private key to encrypt the certificate of the first mesh network node and the first access authentication request message together to generate a first certificate The authentication request message is sent to the authentication server;

[0033] S13. After receiving the first certificate authentication request message, the authentication server uses the public key o...

Abstract

The invention discloses an access authentication method for a wireless mesh network. In the method, a second mesh network node finds out a first mesh network node passing authentication by detecting a node signal existing peripherally, takes the peer-to-peer first mesh network node as an authenticator and sends an access request to the authenticator; and the peer-to-peer authentication among Mesh equipment is realized through ternary authentication among the authenticator, a requestor and an authentication server, and the requestor accesses to Mesh through the authenticator. By adopting the embodiment of the invention, a conflict problem between bidirectional authentication between the mesh network nodes, and MKD (Mesh Key Distributor) logic can be solved.

Description

Technical field [0001] The invention relates to the technical field of wireless mesh networks, in particular to a method for access authentication of wireless mesh networks. Background technique [0002] Wireless Mesh network (also known as wireless mesh network) technology is a new wireless mobile communication technology based on IP access, suitable for regional environment coverage and broadband high-speed wireless access. Each node in the wireless Mesh network can send and receive signals, and each node can directly communicate with one or more peer nodes. Each network node is connected in a wireless multi-hop manner through other adjacent network nodes, which can greatly increase the coverage of the wireless system. [0003] The wireless Mesh network includes four logical network devices, namely Mesh Point (MP), Mesh Access Point (MAP), and Mesh Point with a Portal , MPP) and user terminal (Station, STA). The wireless Mesh network architecture defined in 802.11s is as follo...
