Abstract

Technologies are generally described for providing secured communications. In some examples, a method performed under control of a first device may include transmitting a jamming signal, receiving a mixed signal that includes the jamming signal and an information signal generated by a second device and obtaining the information signal by eliminating the jamming signal from the mixed signal.

Claims

1. A method performed under control of a first device, comprising:

transmitting, by the first device, a jamming signal;

receiving, by the first device, a mixed signal that includes the jamming signal and an information signal generated by a second device; and

obtaining, by the first device, the information signal by eliminating the jamming signal from the mixed signal.

2. The method of claim 1, further comprising:

identifying, by the first device, the jamming signal before transmitting of the jamming signal.

3. The method of claim 2, wherein the jamming signal is generated by the first device.

4. The method of claim 2, wherein the jamming signal is generated by the second device and provided to the first device.

5. The method of claim 1, wherein the information signal is transmitted from the second device while the jamming signal is transmitted from the first device.

6. The method of claim 1, wherein a signal power of the jamming signal is controllable by the first device.

7. The method of claim 1, wherein the obtaining of the information signal is performed based at least in part on adaptive noise canceling.

8. The method of claim 1, wherein the jamming signal includes a random signal.

21. The method of claim 1, wherein the jamming signal is generated by the second device and provided to the first device.

22. The method of claim 1, further comprising:

assigning, by the first device, an identifier to the jamming signal before transmitting of the jamming signal; and

storing, by the first device, the identifier in the first device.

9. A first device, comprising:

a jamming signal identifying unit configured to identify a jamming signal;

a transmitting unit configured to transmit the jamming signal;

a receiving unit configured to receive a mixed signal that includes the jamming signal and an information signal, the information signal being generated by a second device; and

a jamming signal canceling unit configured to eliminate the jamming signal from the mixed signal.

10. The first device of claim 9, wherein the jamming signal is generated by the jamming signal identifying unit.

11. The first device of claim 9, wherein the jamming signal is generated by the second device and provided to the first device.

12. The first device of claim 9, wherein the information signal is transmitted from the second device while the jamming signal is transmitted from the first device.

13. The first device of claim 9, further comprising:

a signal power control unit configured to control a signal power of the jamming signal.

14. The first device of claim 9, wherein the jamming signal canceling unit eliminates the jamming signal from the mixed signal based at least in part on adaptive noise canceling.

15. The first device of claim 9, wherein the jamming signal includes a random signal.

16. A non-transitory computer-readable storage medium having stored thereon computer-executable instructions that, in response to execution, cause a first device to perform operations comprising:

transmitting, by the first device, a jamming signal;

receiving, by the first device, a mixed signal that includes the jamming signal and an information signal generated by a second device; and

obtaining, by the first device, the information signal by eliminating the jamming signal from the mixed signal.

17. The non-transitory computer-readable storage medium of claim 16, wherein the operations further comprise:

identifying, by the first device, the jamming signal before transmitting of the jamming signal.

18. The non-transitory computer-readable storage medium of claim 17, wherein the jamming signal is generated by the first device.

19. The non-transitory computer-readable storage medium of claim 16, wherein the information signal is transmitted from the second device while the jamming signal is transmitted from the first device.

20. The non-transitory computer-readable storage medium of claim 16, wherein the operations further comprise:

controlling, by the first device, a signal power of the jamming signal.

23. The non-transitory computer-readable storage medium of claim 16, wherein the operations further comprise:

assigning, by the first device, an identifier to the jamming signal before transmitting of the jamming signal; and

storing, by the first device, the identifier in the first device.

24. A first device, comprising:

a jamming signal identifying unit configured to assign an identifier to a jamming signal and to store the identifier in the first device;
