METHOD AND APPARATUS FOR REMOTE PORTABLE WIRELESS DEVICE AUTHENTICATION

1 . A method for user authentication, comprising:

receiving a selected signal strength for smart card emulation authentication;

receiving a signal from a portable wireless device radio transceiver;

measuring the signal strength of the signal;

if the signal is at or above the selected signal strength, transmitting one or more signals to the portable radio device radio transceiver requesting user authentication, and if the signal is not at or above a selected signal strength, refusing a request to authenticate by the portable radio device radio transceiver; and

receiving one or more authentication response signals from the portable radio device in response to the request for user authentication, the one or more response signals including at least authentication information unique to a user.

2 . The method of claim 1 , further comprising presenting a user interface containing data representing a selectable proximity range for smart card emulation authentication.

3 . The method of claim 1 , wherein the one or more signals includes a request for a security certificate.

4 . The method of claim 1 , wherein the one or more response signals includes a security certificate.

5 . The method of claim 1 , wherein the one or more response signals includes a coded response to a challenge issued by the smart card reader emulation device, wherein the coded response is based at least in part on the challenge and one or more encryption keys.

6 . A method for user de-authentication, comprising:

receiving a selected signal strength for smart card emulation authentication;

receiving one or more response signals from the portable wireless device in response to a request for user authentication, the smart card reader emulation device radio transceiver receiving a signal; and

monitoring the strength of the signal, so that if the signal is at or below the selected signal strength, the smart card reader emulation device de-authenticates a portable wireless device associated with the portable wireless device radio transceiver.

7 . The method of claim 6 , further comprising presenting a user interface containing data representing a selectable proximity range for smart card emulation authentication.

8 . The method of claim 6 , wherein the threshold signal strength is set by a user.

9 . The method of claim 6 , wherein the threshold signal strength is set by one or more security policies.

10 . The method of claim 6 , wherein the smart card reader emulation device de-authenticates the portable wireless device by erasing one or more password values from memory associated with the smart card reader emulation device.

11 . The method of claim 6 , wherein the smart card reader emulation device de-authenticates the smart phone by locking an operating system associated with the smart card reader emulation device.

12 . An apparatus for user authentication comprising:

logic operable to:

receive a selected signal strength for smart card emulation authentication;

receive a signal from a portable wireless device radio transceiver;

measure the signal strength of the signal;

if the signal is at or above the selected signal strength, transmit one or more signals to the portable radio device radio transceiver requesting user authentication, and if the signal is not at or above a selected signal strength, refuse a request to authenticate by the portable radio device radio transceiver; and

receive one or more authentication response signals from the portable radio device in response to the request for user authentication, the one or more response signals including at least authentication information unique to a user.

13 . The apparatus of claim 12 , further comprising presenting a user interface containing data representing a selectable proximity range for smart card emulation authentication.

14 . The apparatus of claim 12 , wherein the one or more signals includes a request for a security certificate.

15 . The apparatus of claim 12 , wherein the one or more response signals includes a security certificate.

16 . The apparatus of claim 12 , wherein the one or more response signals includes a coded response to a challenge issued by the smart card reader emulation device, wherein the coded response is based at least in part on the challenge and one or more encryption keys.

17 . A computer-readable storage medium comprising executable instructions that when executed by one or more processors causes the one or more processors to:

receive a selected signal strength for smart card emulation authentication;

receive a signal from a portable wireless device radio transceiver;

measure the signal strength of the signal;

if the signal is at or above the selected signal strength, transmit one or more signals to the portable radio device radio transceiver requesting user authentication, and if the signal is not at or above a selected signal strength, refuse a request to authenticate by the portable radio device radio transceiver; and

receive one or more authentication response signals from the portable radio device in response to the request for user authentication, the one or more response signals including at least authentication information unique to a user.
