Authenticating method for short-distance radio devices and a short-distance radio device
First Claim
1. A wireless communication apparatus comprising:
- a communicating unit configured to communicate with another wireless communication apparatus included in a first coverage area,wherein the wireless communication apparatus is configured to execute instructions to;
process an authentication with the another wireless communication apparatus in a second coverage area that is smaller than said first coverage area, wherein the authentication processing with the another wireless communication apparatus is automatically initiated when the another wireless communication apparatus enters in the second coverage area, andswitch the coverage area of the wireless communication apparatus, prior to the initiation of the authentication with the another wireless communication apparatus, from the first coverage area to the second coverage area.

Abstract
The invention provides a method for making mutual authentication between short-distance radio devices automatically or after confirmation by users, and a short-distance radio device for realizing the method. In a condition where a plurality of radio devices exist, each of the radio devices comprising a data communicating unit for performing short-distance radio communication and an authenticating unit for performing authentication of the radio device, the authenticating unit performs mutual authentication between two radio devices automatically or after confirmation by users of the radio devices when the two radio devices come closer to each other to such an extent that coverage areas of radio waves generated by the radio devices overlap with each other.
