ABSTRACT:
A wireless LAN access authentication system capable of shortening the time required for an access authentication procedure of a radio terminal apparatus. In this wireless LAN access authentication system, when a radio terminal apparatus116of a user who has sent an access request is already registered through initial access, a gateway apparatus111searches for a WEP key assigned to the radio terminal apparatus116through a WEP key control section306and redistributes the WEP key registered beforehand to a new access point section124in the destination area and the radio terminal apparatus116. The radio terminal apparatus116and access point section124to which the WEP key has been distributed encrypt transmission/reception data in a predetermined radio section using the redistributed WEP key and carry out a communication.
