Authentication Method and System for Wireless Mesh Network

摘要

The disclosure discloses an authentication method and system for a wireless mesh network. The method comprises: when a new node accesses a network and the node is a Mesh Point (MP), the MP selects one authenticated node from neighbor nodes as a father node, and a uniquely identified secure path exists between the father node and an AC; the MP uses the father node as an authentication point to perform authentication; and after being transmitted to the AC through the secure path between the father node and the AC, which then forwards an authentication message to an AS; similarly, a return message of the AS is forwarded by the AC to the father node through the secure path, and the MP is authenticated. The authentication message is saved on the AC at the same time, so as to facilitate the second authentication of the MP.

1. An authentication method for a wireless mesh network, comprising:
when a new node accesses a network and the node is a Mesh Point (MP), the MP selecting one authenticated node from neighbor nodes as a father node, and establishing a peer-to-peer link with the father node, wherein a uniquely identified secure path exists between the father node and an Access Controller (AC) to identify validity of the father node; the father node receiving an authentication request message initiated by the MP, transmitting the authentication request message to the AC through the secure path between the father node and the AC which then forwards the authentication request message to an Authentication Server (AS), and receiving an authentication response message fed back by the AS; and the father node transmitting an authentication state and key information carried in the authentication response message to the AC which then maintains authentication information of a valid node that has been authenticated.
