ABSTRACT:
In an encryption key setting system of the present invention, in response to an operation of a registration button127, an access point20restricts the coverage of radio wave transmitted from the access point20from a general radio communication area AR1to a narrower security communication area MR1.The access point20subsequently delivers a WEP key to a terminal50, confirms the successful delivery, and registers a MAC address of the terminal50. The terminal50sets the delivered WEP key in itself. This arrangement desirably allows for new enrollment of a terminal for a wireless LAN by a simple method, while effectively preventing leakage of data representing an encryption key.
