Communication system, information processing apparatus, method and computer program

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.

AI Technical Summary

Benefits of technology

The present invention aims to make wireless communications easier and quicker, while ensuring security without needing additional hardware like RF tags or infrared modules. It allows for easy and quick start-up of wireless communications, and ensures security by preventing unauthorized devices from performing wireless communications.

Problems solved by technology

Therefore, although the RF tag, the infrared module, etc. are only for establishing the Bluetooth communications etc. by means of the wireless communication module provided in addition to them, it is necessary to prepare them for causing the Bluetooth communication etc. to start promptly only by bringing the devices into proximity to each other, which increases the cost accordingly.
