Abstract

A system includes a transmit unit to transmit a signal including a data key, and a receiving unit to receive the signal. The receiving unit to determine an encryption key based at least in part on the data key and to decrypt encrypted data using the encryption key.

Claims

1. A method of securing data, the method comprising:

receiving a signal from a fixed location transmitter, the signal including a data key;

determining an encryption key based at least in part on the data key; and

decrypting encrypted data using the encryption key.

2. The method of claim 1, further comprising receiving an input, the method further comprising determining the encryption key based at least in part on the data key and at least in part on the input.

3. The method of claim 2, wherein the input is a password.

4. The method of claim 2, wherein the input is a receiving unit identifier.

5. The method of claim 2, wherein the input is a device identifier.

6. The method of claim 1, further comprising receiving a second signal from a second fixed location transmitter, the second sign including a second data key.

7. The method of claim 6, wherein determining the encryption key includes determining the encryption key based at least in part on the data key and the second data key.

8. The method of claim 1, wherein determining the encryption key includes determining the encryption key using a receiving unit, the method further comprising providing the encryption key to a device coupled to the receiving unit.

9. The method of claim 1, wherein decrypting the encrypted data includes decrypting data stored on the receiving unit.

10. The method of claim 1, wherein the signal includes status data, wherein a receiving unit prevents access to the encrypted data based at least in part on the status data.

11. The method of claim 1, further comprising transmitting a confirmation signal to fixed location transmitter.

13. The method of claim 1, further comprising denying access to the encrypted data based at least in part on an absence of the signal.

12. (canceled)

14. An apparatus comprising:

a receiver to receive a signal from a fixed location transmitter, the signal including a data key; and

a computational circuitry coupled to the receiver, the computational circuitry to permit access to data based at least in part on the data key.

15. The apparatus of claim 14, wherein the computational circuitry is to deny access in the absence of the signal.

19. The apparatus of claim 14, wherein the data key forms at least part of an encryption key and wherein the computational circuitry is to decrypt the data using the encryption key.

20. The apparatus of claim 14, further comprising an interface to a computational device.

21. The apparatus of claim 20, wherein the interface comprises a universal serial bus (USB) interface.

22. The apparatus of claim 14, wherein the receiver includes an infrared receiver.

23. The apparatus of claim 14, further comprising a radio frequency (RF) transponder.

26. A system comprising:

a transmit unit to transmit a signal including a data key; and

a receiving unit to receive the signal, the receiving unit to determine an encryption key based at least in part on the data key and to decrypt encrypted data using the encryption key.

27. The system of claim 26, further comprising a device coupled to the receiving unit, the device to store the encrypted data and to receive the encryption key from the receiving unit.

28. The system of claim 26, wherein the encrypted data is stored on the receiving unit.

29. The system of claim 26, wherein the receiving unit includes a universal serial bus (USB) interface.

30. The system of claim 26, wherein the receiving unit includes an IR receiver.

31. The system of claim 26, wherein the receiving unit includes an RF transponder.

33. The system of claim 26, further comprising a control and monitoring system in communication with the transmit unit.

35. The system of claim 33, wherein the control and monitoring system provides the data key to the transmit unit.
