Wireless switching network re-authentication method based on wireless LAN secure standard WAPI

Abstract

This invention relates to a re-authentication method for radio exchange network based on wireless LAN safety standard WAPI characterizing in transmitting basic key identification and session key generated by the access point connected to the terminal to a wireless exchange after applying WAPI for discrimination for the first time, which lists the identification and the session key to lists corresponding to each other and buffer-stores them, when the terminal roams to the next access point and sends an associated request including the basic key identification, said new access point sends a discrimination request and the wireless exchange audits that there is the basic key identification and sends the response packets including corresponding session key to it to communicate with the terminal with the session key, if the identification does not exist, then authentication will be done again.

Description

technical field [0001] The invention relates to a wireless network security application method, in particular to an application method of the wireless local area network security standard WAPI (WLAN Authentication and Privacy Infrastructure, wireless local area network identification and security infrastructure) in the wireless mesh network. Background technique [0002] In the next 10 to 15 years, with the proliferation of wireless and mobile devices, wireless technology will have a major impact on the development of next-generation Internet networks. Various new real-time streaming media applications in the wireless environment put forward new requirements for network roaming and handover capabilities. Research has found that re-authentication delay is a key factor affecting roaming handover delay. Therefore, in the application of wireless LAN authentication and security infrastructure WAPI In the wireless network, a pre-authentication mechanism is proposed to solve the pr...

Problems solved by technology

In a large-scale network, it will be very complicated for STA to generate and maintain this list, thus increasing the burden on STA;

[0009] (4) In a large-scale wireless network, the pre-authentication method cannot meet the fast moving needs of users, which is not conducive to the further expansion of the network
