Title:
METHOD AND APPARATUS FOR AUTHENTICATION IN WIRELESS LAN SYSTEM
Document Type and Number:
Japanese Patent JP3702812
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method and an apparatus for authentication in a wireless LAN system which can concurrently achieve delivery of an encryption key for maintaining concealment between only parties performing wireless communication and an authenticating procedure and can simplify each authenticating procedure to the same AP (a base station) performed by a S TA (a mobile terminal) completing initial authentication after releasing the authentication.
SOLUTION: The STA searches whether a MAC address of the AP intending to perform the wireless communication exists in an AP information managing table maintained by the STA. If the MAC address does not exist in the AP information managing table, a request for authenticating a public key is transmitted to the AP. If the MAC address exists in the AP information managing table, a request for re-authenticating the public key is transmitted to the AP.
