Wireless mesh network access security authentication method based on WLAN

Abstract

The invention disclose a security certificating method for the access of the wireless mesh network based on a wireless local area network in the technical field of wireless networks. When both certificating sides enter a PLM process used for exchanging security parameters after completing 802.11 open certification; a PLM state machine takes over the operation of a 802.11 state machine; the PLM process is composed of a pair of equivalent link requesting / equivalent link confirming messages respectively sent by both certification sides; a 802.11i / RSN security parameter and a 802.11s / MSA security parameter are mutually consulted, and a storage key used for pre-certification is selected, and the role of each during the following EAP certification stage is determined; the PLM state machine controls a mechanism for transceiving and retransmitting the message; and when the PLM process is over, the mechanism is recontrolled by the 802.11 state machine, and an internal event calling IOCTL is produced to notify an EAP user end to prepare to begin an EAP certification process and four times of handshake interaction. The method satisfies the new features such as the dynamical self-organization of a WLAN Mesh network, and has reliable safety performance.

Description

technical field [0001] The invention relates to an access security authentication method in the technical field of wireless networks, in particular to a wireless mesh network access security authentication method based on a wireless local area network. Background technique [0002] Wireless Mesh Network (Wireless Mesh Network) is an emerging wireless access technology. Because of its self-organization, easy expansion, low cost and other characteristics, it is widely used in municipal management, disaster relief, security monitoring, industrial management, medical emergency and other fields. In view of its main application fields, how to ensure the security of Mesh networks is one of the key issues for the successful application of this technology. [0003] Madwifi is a system driver developed for Atheros (Atheros Communications Corporation) 802.11 wireless network chip, which is mainly used for the functional interaction between the operating system and the wireless network...

AI Technical Summary

Problems solved by technology

Its disadvantages are also obvious: First of all, the number of messages in this authentication method is twice that of the ordinary 802.11i protocol, and the implementation will greatly reduce the network performance, which is unacceptable for wireless networks

Secondly, this solution cannot really solve the self-organization problem of Mesh nodes, because not all Mesh nodes have the function of providing authentication for other nodes, such an authentication method can easily generate a large amount of network overhead and then fail to authenticate

In the end, the document did not give the implementation details, and its specific implementation feasibility is also questionable.
