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. |
