Abstract

The present invention provides easy and prompt initiation of wireless communications in which security is ensured requiring additional hardware. A connection button of a PDA or first device is operated and a connection request is broadcast. If the PDA and a portable phone are in near each other, and a reception intensity of the connection request is equal to or higher than a threshold value, a request of the PDA is granted by the portable phone. Then, an encryption key is newly generated by the portable phone, and is transmitted to the PDA. An encryption key and communication parameter transmitted from the portable phone are acquired. Encrypted communications using the encryption key generated by the portable phone are established based on the communication parameter.
