Abstract

One or more systems and methods are disclosed to securely authenticate one or more wireless communication devices using a subscriber identification mechanism provided by a wireless communication device. The subscriber identification mechanism provides one or more keys and algorithms used in the authentication of a wireless communication device. In one embodiment, the subscriber identification mechanism comprises a subscriber identity module (SIM) card capable of being easily inserted into a wireless communication device. In one embodiment, wireless signal transmission occurs over a GSM/GPRS/EDGE network.

Claims

1. A method to authenticate a first wireless communication device comprising:

receiving a value by said first wireless communication device from a wireless carrier; and

transmitting said value to a second wireless communication device, said second wireless communication device transmitting an output back to said carrier for authentication processing, said output generated using an algorithm, said value and a key.

2. The method of claim 1 wherein said value comprises a random numeric value.

3. The method of claim 1 wherein said key is stored in a subscriber identification mechanism of said second wireless communication device.

4. The method of claim 1 wherein said receiving a value from said wireless carrier occurs by way of a wide area air interface.

5. The method of claim 1 wherein said transmitting said value to a second wireless communication device occurs by way of a local area air interface.

6. The method of claim 1 wherein said second wireless communication device transmitting said output back to said carrier occurs by way of a first transmission to said first wireless communication device from said second wireless communication device and a second transmission from said first wireless communication device to said carrier.

7. The method of claim 6 wherein said first transmission occurs by way of a local area air interface.

8. The method of claim 6 wherein said second transmission occurs by way of a wide area network air interface.

9. The method of claim 5 or claim 7 wherein said local area network air interface comprises a 802.11, Bluetooth, 27 Mhz, or 900 Mhz air interface.

10. The method of claim 4 or claim 8 wherein said wireless wide area network air interface comprises a GSM/GPRS/EDGE, UMTS, WCDMA, or 3G air interface.

11. The method of claim 1 further comprising:

receiving an input sequence by said first wireless communication device; and

transmitting said input sequence to said secondary wireless communication device, said input sequence verified by said second wireless communication device, said second wireless communication device enabling access to a subscriber identification mechanism if said input sequence is correct.

12. The method of claim 11 wherein said sequence comprises a four digit number.

13. The method of claim 11 wherein said receiving an input sequence is performed to initialize automatic pairing of said first wireless communication device to said second wireless communication device.

14. The method of claim 1 wherein said first wireless communication device comprises a computer with wireless modem.

15. The method of claim 3 wherein said subscriber identification mechanism comprises a subscriber identity module (SIM) card.

16. The method of claim 11 further comprising inputting an unblocking sequence to facilitate input of said input sequence after said input sequence has been input incorrectly a specified number of times.

17. The method of claim 11 wherein said receiving is performed by a user inputting on a keypad of said first wireless communication device.

18. The method of claim 3 wherein said subscriber identification mechanism uniquely identifies a subscriber'"'"'s billing account.

19. A system for authenticating a first wireless communication device comprising a subscriber identification mechanism associated with a second wireless communication device, said second wireless communication device receiving a value originating from a wireless carrier, said subscriber identification mechanism generating an output using said value and a key, said second wireless communication device transmitting said output to said wireless carrier, said wireless carrier having an authentication center capable of said authenticating said first wireless communication device using said output, said authentication center enabling said first wireless communication device for call operation if said authenticating is successful.

20. The system of claim 19 wherein said second wireless communication device receiving a value occurs by way of a first transmission from said wireless carrier to said first wireless communication device and a second transmission from said first wireless communication device to said second wireless communication device.

21. The system of claim 19 wherein said first transmission occurs by way of a wide area air interface.

22. The system of claim 20 wherein said second transmission occurs by way of a local area air interface.

23. The system of claim 21 wherein said wide area air interface comprises a GSM/GPRS/EDGE, UMTS, WCDMA, or 3G air interface.

24. The system of claim 22 wherein said local area air interface comprises an 802.11, Bluetooth, 27 Mhz, or 900 Mhz air interface.

25. The system of claim 19 wherein transmitting said output occurs by way of a first transmission from said second wireless communication device to said first wireless communication device and a second transmission from said first wireless communication device to said carrier.

26. The system of claim 25 wherein said first transmission occurs by way of a local area air interface.

27. The system of claim 25 wherein said second transmission occurs by way of a wide area air interface.

28. The system of claim 26 wherein said local area air interface comprises an 802.11, Bluetooth, 27 Mhz, or 900 Mhz air interface.

29. The system of claim 27 wherein said wide area air interface comprises a GSM/GPRS/EDGE, UMTS, WCDMA, or 3G air interface.

30. The system of claim 19 wherein said first wireless communication device comprises a computer with one or more wireless modem cards or wireless PDA.

31. The system of claim 19 wherein said second wireless communication device comprises a cellular phone or smart phone capable of incorporating a subscriber identification mechanism.

32. The system of claim 19 wherein said subscriber identification mechanism comprises a subscriber identity module (SIM) card.

33. The system of claim 19 wherein said value comprises a random number.

34. A method for authenticating a first wireless communication device comprising generating an output by a second wireless communication device, said output generated using one or more algorithms, a value, and a key, wherein said value is received from a wireless carrier.

35. The method of claim 34 further comprising transmitting said output to said wireless carrier.

36. The method of claim 35 further comprising authenticating said output by an authentication center of said wireless carrier, wherein said authenticating enables operation of said first wireless communication device.
