AUTHENTICATING METHOD IN RADIO LAN SYSTEM AND AUTHENTICATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide structure, capable of safely performing authentication by connecting many subscriber stations (STA) with an access point(AP) for an encipher authenticating method and an authentication device of a radio LAN system in compliance with IEEE 802.11. SOLUTION: An authentication request is transmitted from many STAs 1, consisting of a data terminal 10 and a radio LAN card 20, to the AP 2 (S1). A MAC address is transmitted to an authentication server (RADIUS) 3 by a protocol of the authentication server 3 (S8) by the AP 2. The authentication server 3 transmits a challenge text to the AP 2 (S10), after executing authentication of the MAC address (S9). Encipher authentication is performed with the STAs 1 (S2) to (S6) according to a processing of WEP algorithm determined by the IEEE 802.11 by the AP 2.
