Abstract

A wireless apparatus including a button; a wireless communication interface; a processing unit to output encryption key information to another wireless apparatus using the wireless communication interface with lower transmission output than transmission output of information other than the encryption key information, responsive to detection of user'"'"'s operation for the button; and a memory to store the output encryption key information corresponding to the another wireless apparatus. The wireless communication interface receives wireless signals from the another wireless apparatus and the processing unit decodes the information contained in the wireless signals and encrypted with the encryption key information. Also disclosed is an encryption key information managing method of managing encryption key information and a non-transitory readable-by-computer recording medium recorded with a program executed by a computer to manage encryption key information.

Claims

1. A wireless apparatus, comprising:

a button;

a wireless communication interface;

a processing unit to output encryption key information to another wireless apparatus using the wireless communication interface with lower transmission output than transmission output of information other than the encryption key information, responsive to detection of user'"'"'s operation for the button; and

a memory to store the output encryption key information corresponding to the another wireless apparatus,

wherein the wireless communication interface receives wireless signals from the another wireless apparatus and the processing unit decodes the information contained in the wireless signals and encrypted with the encryption key information.

2. The wireless apparatus according to claim 1, wherein the wireless communication interface comprises a near communication module incapable of performing communications beyond a predetermined distance, the near communication module forms a communication path for outputting the encryption key information within the predetermined distance.

3. The wireless apparatus according to claim 1, further comprising a wire communication interface.

4. A encryption key information managing method of managing encryption key information, comprising:

detecting user'"'"'s operation for a button of a wireless apparatus;

generating encryption key information responsive to the detecting;

outputting the encryption key information to an another wireless apparatus using a wireless communication interface of the wireless apparatus with lower transmission output than transmission output of information other than the encryption key information;

storing the output encryption key information corresponding to the another wireless apparatus;

receiving wireless signals from the another wireless apparatus; and

decoding the information contained in the wireless signals and encrypted with the encryption key information.

5. The encryption key information managing method according to claim 4, wherein the wireless communication interface comprises a near communication module incapable of performing communications beyond a predetermined distance, and the outputting outputs the generated encryption key information through the near communication module.

6. A non-transitory readable-by-computer recording medium recorded with a program executed by a computer to manage encryption key information, comprising:

detecting user'"'"'s operation for a button of a wireless apparatus;

generating encryption key information responsive to the detecting;

outputting the encryption key information to another wireless apparatus using a wireless communication interface of the wireless apparatus with lower transmission output than transmission output of information other than the encryption key information;

storing the output encryption key information corresponding to the another wireless apparatus;

receiving wireless signals from the another wireless apparatus; and

decoding the information contained in the wireless signals and encrypted with the encryption key information.

7. The non-transitory readable-by-computer recording medium recorded with a program according to claim 6, wherein the wireless communication interface comprises a near communication module incapable of performing communications beyond a predetermined distance, and the outputting outputs the generated encryption key information through the near communication module.
