Method and apparatus for remote portable wireless device authentication

1. A method, carried out by a first apparatus and a second apparatus, for user authentication comprising:

establishing a very short range wireless communication link between the first apparatus and the second apparatus; and

authenticating a user of the first apparatus by the second apparatus directly using a different and short range peer to peer wireless communication link between the first apparatus and the second apparatus in response to establishing the very short range wireless communication link.

2. The method of claim 1 wherein authenticating a user of the first apparatus by the second apparatus using a different and short range peer to peer wireless communication link comprises communicating user logon authentication information between the first and second apparatus using the established short range peer to peer wireless link and wherein link keys are exchanged over the very short range peer to peer wireless communication link for use with the short range wireless link.

3. The method of claim 1 wherein the very short range wireless communication link is a near field communication link and wherein the short range communication link has less than a 30 meter range and wherein the method comprises passing user authentication credentials from the first apparatus to the second apparatus.

4. The method of claim 1 wherein authenticating the user of the first apparatus by the second apparatus using a different and short range peer to peer wireless communication link comprises sending, without user intervention, by the second device a request to the first device for user authentication information and sending by the first device, a reply without user intervention, that includes a user certificate.

5. The method of claim 4 wherein establishing the very short range wireless communication link between the first apparatus and the second apparatus comprises a near field communication tap operation to initiate setup of the different and short range peer to peer wireless communication link.

6. The method of claim 1 comprising wherein authenticating the user of the first apparatus by the second apparatus using a different and short range peer to peer wireless communication link comprises sending, by the second apparatus, a user logon challenge to the first apparatus in direct response to the very short range wireless link being established and receiving a user logon reply from the first apparatus based on the user logon challenge using the short range peer to peer wireless link.

7. A system for providing user authentication comprising:

a first apparatus comprising:

a first very short range wireless transceiver;

a first short range peer to peer wireless transceiver; and

first logic operatively coupled to both the first very short range transceiver and the first short range peer to peer wireless transceiver;

a second apparatus comprising:

a second very short range wireless transceiver;

a second short range peer to peer wireless transceiver; and

second logic operatively coupled to both the second very short range transceiver and the second short range peer to peer wireless transceiver;

wherein the first and second logic are operative to:

establish a very short range wireless communication link between the first apparatus and the second apparatus; and

authenticate a user of the first apparatus by the second apparatus directly using a different and short range peer to peer wireless communication link between the first apparatus and the second apparatus in response to establishing the very short range wireless communication link.

8. The system of claim 7 wherein authenticating a user of the first apparatus by the second apparatus using a different and short range peer to peer wireless communication link comprises communicating user logon authentication information between the first and second apparatus using the established short range peer to peer wireless link and wherein link keys are exchanged over the very short range peer to peer wireless communication link for use with the short range wireless link.

9. The system of claim 7 wherein the very short range wireless communication link is a near field communication link and wherein the short range communication link has less than a 30 meter range and wherein the method comprises passing user authentication credentials from the first apparatus to the second apparatus.

10. The system of claim 7 wherein authenticating the user of the first apparatus by the second apparatus using a different and short range peer to peer wireless communication link comprises sending, without user intervention, by the second device a request to the first device for user authentication information and sending by the first device, a reply without user intervention, that includes a user certificate.

11. The system of claim 10 wherein establishing the very short range wireless communication link between the first apparatus and the second apparatus comprises a near field communication tap operation to initiate setup of the different and short range peer to peer wireless communication link.

12. The system of claim 7 comprising wherein authenticating the user of the first apparatus by the second apparatus using a different and short range peer to peer wireless communication link comprises sending, by the second apparatus, a user logon challenge to the first apparatus in direct response to the very short range wireless link being established and receiving a user logon reply from the first apparatus based on the user logon challenge using the short range peer to peer wireless link.
