Abstract

A key information issuing device (1, 1A, 1B) issuing key information to a key information retaining device (2, 2A, 2B) includes an authentication module (14, 3) authenticating an issuer of the key information, an output module (13) outputting the key information to the key information retaining unit, and a recording module (11) recording a mapping of the issued key information to the key information retaining unit. The key information is issued in response to an indication of the authenticated issuer.

Claims

1. A wireless device wirelessly connected to another wireless device, comprising:

a key information input module inputting key information for encrypting information, the key information being generated by the another wireless device responsive to an operation of a user for an operation module of the another wireless device and input via a first communication path wirelessly connected to the another wireless device;

a recording module recording the key information;

an operation module detecting an operation of a user;

an encryption module encrypting user'"'"'s operation based input information with the key information; and

a transmission module transmitting the encrypted input information to the another wireless device wirelessly via a second communication path.

2. The wireless operation device according to claim 1, wherein said key information input module includes a near communication module incapable of performing communications beyond a predetermined distance and forming the first communication path within the predetermined distance.

3. The wireless device according to claim 1, further comprising a setting module setting an execution or non-execution of the encryption,

wherein said encryption module encrypts the input information when the execution of the encryption is set.

4. The wireless device according to claim 1, further comprising:

a confirmation module confirming whether there is a response signal from the another wireless device with respect to the transmitted input information,

wherein the transmission of the input information is stopped if the response signal is not obtained.

5. The wireless device according to claim 1, further comprising:

a simulated information generation module generating simulated information simulating the user'"'"'s operation based input information; and

wherein a transmission module transmits any one of the user'"'"'s operation based input information or the simulated information to the another wireless device.

6. The wireless device according to claim 5, wherein the simulated information is transmitted irrespective of whether the user'"'"'s operation is made or not.

7. The wireless device according to claim 1, wherein the operation module of the another wireless device is a button.

8. A device control method based on wireless signals, comprising:

inputting key information for encrypting information, the key information being generated by another wireless device different from the device responsive to an operation of a user for an operation module of the another wireless device and input via a first communication path wirelessly connected to the another wireless device;

recording the key information for the encryption;

detecting an operation of a user to an operation module of the device;

encrypting user'"'"'s operation based input information with the key information; and

transmitting the encrypted input information to the another wireless device through on the wireless signals via a second communication path.

9. The device control method according to claim 8, wherein inputting the key information involves inputting the key information via the second communication path in near communications impossible of communications beyond a predetermined distance.

10. The device control method according to claim 8, further comprising setting an execution or non-execution of the encryption,

wherein encrypting the input information involves encrypting the input information when the execution of the encryption is set.

11. The device control method according to claim 8, further comprising:

confirming whether there is a response signal from the another wireless device with respect to the transmitted input information,

wherein the transmission of the input information is stopped if the response signal is not obtained.

12. The device control method based on wireless signals, according to claim 8, further comprising:

generating simulated information simulating the user'"'"'s operation based input information;

wherein said transmitting includes any one of transmitting the user'"'"'s operation based input information to the device and transmitting the simulated information to the another wireless device.

13. The device control method according to claim 12, wherein the simulated information is transmitted irrespective of whether the user'"'"'s operation is made or not.

14. A readable-by-computer recording medium recorded with a program executed by a computer to implement device control using wireless signals, comprising:

inputting key information for encrypting information, the key information being generated by another wireless device different from the device responsive to an operation of a user for an operation module of the another wireless device and input via a first communication path wirelessly connected to the another wireless device;

recording the key information for the encryption;

detecting an operation of a user to an operation module of the device;

encrypting user'"'"'s operation based input information with the key information; and

transmitting the encrypted input information to the another wireless device through on the wireless signals via a second communication path.

15. The readable-by-computer recording medium recorded with a program according to claim 14, wherein inputting the key information involves inputting the key information via the second communication path in near communications impossible of communications beyond a predetermined distance.

16. The readable-by-computer recording medium recorded with a program according to claim 14, further comprising setting an execution or non-execution of the encryption,

wherein encrypting the input information involves encrypting the input information when the execution of the encryption is set.

17. The readable-by-computer recording medium recorded with a program according to claim 14, further comprising:

confirming whether there is a response signal from the another wireless device with respect to the transmitted input information,

wherein the transmission of the input information is stopped if the response signal is not obtained.

18. The readable-by-computer recording medium recorded with a program according to claim 14, further comprising:

generating simulated information simulating the user'"'"'s operation based input information;

wherein said transmitting includes any one of transmitting the user'"'"'s operation based input information to the device and transmitting the simulated information to the another wireless device.

19. The readable-by-computer recording medium recorded with a program according to claim 18, wherein the simulated information is transmitted irrespective of whether the user'"'"'s operation is made or not.
