Abstract:
1. An authentication method for a wireless LAN (local area network) system, comprising: transmitting an authentication request from a STA (terminal station) to an AP (access point), wherein said authentication request comprises a request from said STA to connect with said LAN; requesting authentication of said authentication request from said AP to an authentication server, by converting said authentication request to a protocol adaptable to said authentication server; if no problem occurs at hardware or software of said authentication server, checking said authentication request at said authentication server based on a MAC (media access control) address of said STA; executing encryption authentication at said AP with said STA based on a designated encryption algorithm; and if no problem occurs at hardware or software of said authentication server, notifying an authentication completion from said authentication server to said AP, after said authentication server received a response of a completion of said encryption authentication from said AP, wherein said AP stores said MAC address said STA, and wherein, when a problem occurs in hardware or software of said authentication server said AP itself executes authentication of said STA based on said MAC address of said STA.
