Abstract

A device includes a processor having a standby state, a control unit coupled to the processor to receive wireless identification information, and a storage device to store a processor wake policy. The control unit applies the policy to received wireless identification information to wake the processor.

Claims

1. A device comprising:

a processor having a standby state;

a storage device to store a processor wake policy;

a control unit coupled to the processor and arranged to;

receive wireless identification information; and

apply the processor wake policy to receive wireless identification information to wake the processor.

2. The device of claim 1 wherein the wireless identification information comprises RFID packets.

3. The device of claim 2 wherein the control unit validates encrypted and signed RFID packets.

4. The device of claim 1 wherein the control unit selectively discontinues receipt of wireless identification information.

5. The device of claim 1 and further comprising an RFID module having an antenna, circuitry, and a memory bank, the RFID module being coupled to the control unit to provide wireless identification information directly to the control unit, wherein the RFID module memory bank is not directly accessible to the processor.

6. The device of claim 5 wherein the wireless identification information comprises RFID packets that include a unique RF TAG ID, and wherein packets not having the unique RF TAG ID are rejected.

7. The device of claim 5 wherein the RFID module is directly coupled to the control unit via a secure connection.

8. The device of claim 1 and further comprising a context module to provide an interface to a user of the device to define the processor wake policy based on location of the device.

9. The device of claim 8 wherein the interface is provided to the user of the device to define the processor wake policy based on specific applications and types of applications.

10. The device of claim 1 and further comprising a cloud module to store the processor wake policy on remote storage.

11. The device of claim 10 wherein the cloud module encrypts the processor wake policy prior to storing the policy on remote storage.

12. A mobile device comprising:

a processor having a standby state;

a storage device to store a processor wake policy;

a touchscreen coupled to the processor;

an RFID module to receive RFID packets;

a control unit coupled to the processor and to the RFID module;

the control unit arranged to apply the processor wake policy to received RFID packets to wake the processor.

13. The device of claim 12 wherein the control unit validates encrypted and signed RFID packets.

14. The device of claim 13 wherein the control unit selectively discontinues receipt of wireless identification information upon receipt of a selected number of unauthorized RFID packets.

15. The device of claim 13 wherein only RFID packets that include a unique RF TAG ID are validated.

16. The device of claim 13 and further comprising a context module to execute on the processor to provide an interface to a user of the device to define the processor wake policy based on location of the device.

17. The device of claim 16 wherein the interface is provided to the user of the device to define the processor wake policy based on specific applications and types of applications.

18. The device of claim 13 and further comprising a cloud module to execute on the processor to store the processor wake policy on remote storage.

19. The device of claim 18 wherein the cloud module encrypts the policy prior to storing the processor wake policy on remote storage.

20. A method comprising:

receiving data at a mobile device via a wireless connection;

storing the received data on a computer readable storage device;

validating the received data;

comparing the validated received data to a policy specifying a context of the mobile device; and

waking a processor when the validated received data complies with the policy.

21. The method of claim 20 wherein a control unit performs the comparing independent of the processor and while the processor is not in an awake state.

22. The method of claim 20 wherein the computer readable storage device comprises processor secure storage that is not directly accessible to the processor.

23. A computer readable medium having instructions for causing a device to perform a method, the method comprising:

receiving data at a mobile device via a wireless connection;

validating the received data;

comparing the validated received data to a policy specifying a context of the mobile device; and

waking a processor when the validated received data complies with the policy.

24. The computer readable medium of claim 23 wherein a control unit performs the comparing independent of the processor and while the processor is not in an awake state.

25. The computer readable medium of claim 23 wherein the computer readable storage device comprises processor secure storage that is not directly accessible to the processor.
