Abstract

In one embodiment, the present invention includes a method to store data received at a wireless device from a remote location to a buffer via a security device within the wireless device. In certain embodiments, the data may be secure data sent using a remote direct memory access protocol.

Claims

1. A method comprising:

storing data received at a wireless device from a remote location to a buffer via a security device within the wireless device.

2. The method of claim 1, further comprising receiving the data while an applications processor of the wireless device is in a low power mode.

3. The method of claim 2, further comprising providing connection and buffer information to the security device from the applications processor.

4. The method of claim 2, further comprising performing a handshake between the applications processor and the remote location to receive remote direct memory access protocol information.

5. The method of claim 1, further comprising decrypting the data at the security device using a key provided by the remote location.

6. The method of claim 1, further comprising receiving the data while the wireless device is in a low power mode.

7. The method of claim 1, further comprising receiving remote direct memory access data while an applications processor of the wireless device is in a sleep mode.

8. An apparatus comprising:

a security device of a wireless device to directly store information received from a remote location to a buffer.

9. The apparatus of claim 8, further comprising an applications processor coupled to the security device.

10. The apparatus of claim 9, wherein the applications processor is coupled to provide connection and buffer information to the security device.

11. The apparatus of claim 10, wherein the buffer information identifies a location in the buffer.

12. The apparatus of claim 8, further comprising a network interface card coupled to the security device to divert the information from the remote location to the security device.

13. The apparatus of claim 12, further comprising a scalable link coupled between the network interface card and the security device.

14. The apparatus of claim 8, wherein the security device comprises a trusted module having at least one encryption mechanism.

15. The apparatus of claim 8, wherein the buffer comprises a flash memory.

16. The apparatus of claim 8, wherein the information comprises remote direct memory access data.

17. A method comprising:

directly storing data received from a remote source into a storage medium of a wireless device.

18. The method of claim 17, further comprising receiving and storing the data while the wireless device is in a low power mode.

19. The method of claim 17, further comprising receiving and storing the data while an applications processor of the wireless device is in a sleep mode.

20. The method of claim 17, further comprising using a security device within the wireless device to store the data to the storage medium.

21. The method of claim 20, further comprising pre-storing security information corresponding to the remote source in the security device.

22. The method of claim 19, wherein the applications processor provides an address in the storage medium to a security device before entering the sleep mode.

23. A system comprising:

a security device of a wireless device to directly store data received from a remote location to a buffer; and

a wireless interface coupled to the security device.

24. The system of claim 23, further comprising an applications processor coupled to the security device.

25. The system of claim 24, wherein the applications processor is coupled to provide connection and buffer information to the security device.

26. The system of claim 23, wherein the wireless interface comprises an antenna.

27. An article comprising a machine readable storage medium containing instructions that if executed enable a system to:

directly store information received from a remote source into a storage medium of a wireless device.

28. The article of claim 27, further comprising instructions that if executed enable the system to decrypt the information before storing the information.

29. The article of claim 27, further comprising instructions that if executed enable the system to use a security device within the wireless device to store the information to the storage medium.
