A WEP key is generated from predetermined binary data and stored in an access point. The binary data is converted into an SSID using a predetermined conversion algorithm. The access point transmits the SSID in a beacon. A mobile game apparatus receives the SSID and recovers the binary data from the SSID using the predetermined conversion algorithm. Using the same algorithm as used for generating the WEP key, a WEP key is generated from the recovered binary data. Encrypted communication is performed between the access point and the mobile game apparatus using the WEP key.
