Abstract

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.

Claims15

Dependent claims

A communication system including an access point apparatus connectable to a network and a communication terminal wirelessly communicable to the access point apparatus, wherein:

the access point apparatus comprises:
a connection information storage location for storing connection information for generating key information for performing encrypted communication with the communication terminal and the key information generated from the connection information using a predetermined generation algorithm;
and
transmission programmed logic circuitry configured to transmit the connection information;
and
the communication terminal comprises:
receiving programmed logic circuitry configured to receive the connection information;
key information generation programmed logic circuitry configured to generate key information from the connection information using the same generation algorithm as used for generating the key information stored in the connection information storage location;
and
connection establishing programmed logic circuitry configured to establish a connection for the encrypted communication with the access point apparatus using the key information generated by the key information generation programmed logic circuitry, wherein said key information is generated prior to performing any encrypted communication with the communication terminal.

7 more elements
